What can be cooked from squid: quick and tasty

The asphalt concrete road surface of the Autobahn is constantly exposed to mechanical loads from.

In addition, it is influenced by weather conditions and soil-hydrological factors.

Internal stress and strain roadways caused by these influences, accumulate, which leads to the appearance of defects and destruction of the upper layer of the pavement in the form of cracks and potholes.

In order for the quality of the roadbed to comply with the road safety requirements (Article 12 of the Federal Law of 10.12.1995 No. 196-FZ as amended on 26.07.2017 "On Road Safety"), road construction organizations carry out work to remove worn and damaged layers asphalt concrete pavement(ABP) and replacing them with new layers.

The volumes of old UPS removed annually in each large city RF make tens of thousands of tons over a million tons dismantled asphalt concrete.

Modern technologies for processing old asphalt concrete are resource-saving in nature, since the reclaimed pavement is successfully used in the process of creating a new ABP.

Regeneration of the dismantled ABP is aimed at restoring and improving the technical and operational characteristics of asphalt concrete material in order to reuse it for asphalt paving of highways or other road repair works.

At the end of the service life road surface in its composition retains up to 90% of the useful mass asphalt concrete material suitable for further use.

To make the methods of processing used asphalt more understandable, let's take a closer look at the structure of the pavement and the properties of the main elements that make up it.

ABP road garments are the most common designs of all autobahn categories.

The above is the scheme of the so-called "road pie"- multilayer pavement with obligatory asphalt concrete pavement at least 15 cm thick.

GOST 9128-2013"Asphalt concrete mixes ..." defines the composition of asphalt concrete mixes (p. 3.1) as rationally selected mixtures of crushed stone, gravel, sand and mineral powder with bitumen, mixed in a heated state. At the same time, it is customary to call asphalt concrete (clause 3.2) an asphalt concrete mixture (hereinafter referred to as ABS) in a compacted state after being rolled with rollers.

Distinguish between concepts asphalt and asphalt concrete used in road construction practice:

1. Asphalt is astringent organic matter natural or artificial with different content of bitumen in its composition(from 13% to 75%). It is a mixture of bitumen with sand and gravel. Real natural asphalt consists of heavy petroleum fractions and is little distinguishable from ordinary resin, for which the ancient Greeks called it - mountain resin.
2. Asphalt concrete - the result of technological mixing of bitumen with inert materials- crushed stone, gravel and sand, which significantly increase the strength characteristics of the asphalt concrete mixture. In other words, asphalt concrete is a modified version of the traditional road asphalt pavement.

In ABP, bitumen is only 4.5-6.0%, the rest is crushed stone, gravel and sand.

This gave rise to the adoption of concept of 100% suitability road asphalt pavement for recycling and reuse.

Modern technologies for the regeneration and recycling of asphalt concrete pavements are the processing of an ABP worn out during operation, bringing its technical parameters and physicochemical characteristics to the required level.

The use of dismantled old asphalt concrete allows you to do this when minimum consumption of new binders and inert aggregates.

Removal of waste material

A kind of starting point for starting the processing of old asphalt concrete is the dismantling of the asphalt concrete road.

It is carried out taking into account the state of the layer of the canvas, the type of coating and a number of other factors.

Asphalt pavement removed by layer-by-layer removal of material of the worn-out roadbed, while dismantling either over the entire thickness of the road surface, or only the material of local damaged areas is removed.

In small areas so far use manual ways opening and removing asphalt using tools such as:

• percussion pneumatic tools;
• cutting installations;
• crowbars;
• pick;
• sledgehammers;
• pickaxes.

In large areas removing the UPS without specialized equipment is no longer possible. The teams with jackhammers and shovels were replaced by mini excavators with hydraulic breakers.

Serious competition traditional ways removal of the roadway represent modern road milling cutters equipped with rotating milling drums for cutting old asphalt concrete to the required depth.

The width of the cut strip on the road when removing the pavement depends on the width of the drum and varies from 350 mm to 2200 mm.

The steel teeth of the drums cut off the necessary layer of ABP and cut shallow grooves on the base of the pavement to improve the adhesion of the remaining base material to the new layer of asphalt mixture or reclaimed asphalt concrete.

Milling layers the roadway is carried out in two different ways:

• hot milling, carried out in conditions of preheating of the ABP;
• cold milling, in which work begins without warming up.

Each of the milling methods has its own advantages and disadvantages.

Hot milling

This method for removing ABP was introduced earlier than cold milling was introduced.

With mobile infrared burners fueled by gas (propane-butane mixture) or kerosene, asphalt heats up and softens.

This helps to reduce the amount of effort required to break the pavement to be dismantled.

Disadvantages hot milling are the following circumstances:

• high cost of used fuel resources;
• the risk of equipment fire and the risk of burns to personnel;
• destroyed asphalt material sticks together, making reapplication inconvenient;
• when stored in stacks at the warehouse of the ABZ, pieces of milled asphalt are caked in hot weather, which forces them to be sprinkled with sand or mineral powder.

When choosing hot milling, the priority motive is speed of repair work because the heated UPS shears off quickly and with minimal effort.

Summarizing the above, it can be noted that the hot method is costly, but fast.

Cold way

Cold milling requires more effort and is more time consuming because the pavement layer is removed in its natural solid state.

Benefits of this technique are the following factors:

• invariability of the structure of the coating, which makes it possible to use the removed material in the composition of the prepared asphalt concrete mixture;
• when stored in stacks, pieces of milled asphalt concrete do not cake;
• cost-effectiveness of the milling process.

Asphalt concrete scrap and granules

Dismantling the old UPS results in the formation of pieces of asphalt concrete of various sizes, called asphalt concrete scrap.

As part of such waste - scrap - the main components of the asphalt and asphalt concrete pavement remain - crushed stone, sand and bitumen residues.

The thickness of the removed layers is from 5 to 15 cm.

Piece sizes asphalt is not standardized, however, in the practice of separating asphalt blocks it is customary to divide into three conditional groups:

• small waste, the size of which does not exceed 20 cm;
• average scrap with dimensions of elements 15-40 cm;
• large blocks more than half a meter in size.

Asphalt scrap, being in the status of a secondary resource, is an excellent construction and repair material... The following qualities are considered the advantages of asphalt scrap:

• resistance to mechanical static and dynamic loads;
• resistance to atmospheric moisture and chemically active substances;
• resistance to sudden temperature changes;
• the possibility of further crushing by crushing with a jackhammer;
• low cost.

The average volumetric weight of asphalt scrap is 1800-2200 kg per 1 m3, while for asphalt concrete this parameter is slightly higher - from 2000 to 2450 kg or, respectively, 2-2.45 tons per 1 m3.

Depending on the crushing method pieces of old asphalt concrete get asphalt concrete granulate(hereinafter - ABG) and asphalt crumb which are in great demand. The average density of ABG is from 2100 to 2200 kg / m3.

Standard STO NOSTROY 2.25.35-2011 “Roads. Construction of pavement foundations ”, ABG is defined as crushed old asphalt concrete (clause 3.2), which is allowed to be used in the manufacture of pavements and pavements.

Due to the growing demand for ABG in road repair works introduced GOST R 55052-2012“Granulate of old asphalt concrete. Specifications ", which regulates the requirements for this material by analogy with the European standard for asphalt concrete granulate EN 1310808.

This will raise the bar for the use of ABG as a high quality material for pavement.

In the Russian building materials market, the price of asphalt concrete scrap varies within the range of 100-300 rubles / cubic meter. m, while the secondary ABG is offered at a price RUB 500-1500 per ton.

Recycling and recovery

In world practice, road construction works on the reconstruction of autobahns are successfully used regeneration methods and recycling of used pavement materials, allowing save on the purchase of new building materials.

Quite often, information sources on this topic incorrectly interpret the concepts of regeneration and recycling of asphalt concrete, mixing into one heap the final results of completely different in essence technological concepts.

Let us clarify the features of these processes associated with their names. The term regeneration is taken from the Latin language - "regeneratio" means "rebirth, restoration".

Applied to the reconstruction of motorway pavements regeneration means the restoration of their technical and operational qualities:

• continuity,
• passability,
• accident and safety rates, etc.

And for the ABP itself - restoration of physical and mechanical properties and quality indicators.

Among these properties:

• roughness;
• wear resistance;
• shear stability;
• crack resistance.

Experts call the reuse of the old UPS material English word"Recycling" meaning recirculation- reuse, return to circulation, alteration / processing for useful use.

Recycling of the old pavement can be carried out without regenerating its properties, for example, in the case of using granulate of asphalt scrap to strengthen road shoulders, there is no need to restore the plasticity necessary for the asphalt concrete mixture when it is reused in the road surface.

ABP recycling algorithm

For the technical implementation of the recycling of old asphalt concrete in order to use it as a top layer of the road surface the following works are in progress:

1. Removing the damaged layer hot or cold milling coatings.
2. Manufacturing ABG by crushing the layer removed by milling to the size of crushed stone fractions.
3. Heating the granulate in a special furnace without an open flame to restore the binding and plastic properties of old bitumen in the composition of removed asphalt concrete.
4. Adding a portion of fresh bitumen for adjusting the binding and plastic properties of the asphalt mixture in accordance with the recipe.

When carrying out work on the processing of old asphalt, the following requirements must be observed, aimed at ensuring the quality of the new asphalt concrete pavement:

1. For new asphalt mix obtained from the recycling process, it is necessary to carry out preliminary design its composition, in which the formulation of the new asphalt concrete mixture, the grain composition of the inert components, the viscosity of bitumen and its content in the old asphalt concrete, the processing technology and the type of mixing plant, the amount of old asphalt concrete in the composition of the regenerated mixture are determined.
2. When heating granulate in ovens, it is necessary to observe temperature conditions , preventing the beginning of evaporation of light fractions from the composition of the binder and its burnout, which can occur when the flash point of bitumen is exceeded (180-220 deg. C for viscous and 45-110 deg. C for liquid bitumen).

Quantitative indicators for the content of granulate and additives in new asphalt concrete should be determined by laboratory methods in accordance with GOST, TU and other regulatory documents.

Recycling methods of asphalt concrete waste

By venue recycling technological measures distinguish two ways of processing removed road building material:

• regeneration of old asphalt concrete in stationary conditions at an asphalt concrete plant (ABZ), which involves preliminary dismantling of the road surface and sending asphalt concrete scrap to the ABZ for processing;
• recycling of ABP directly at the site of the reconstruction of the canvas, which involves re-laying the pavement using special road equipment - remixers, recyclers, asphalt heaters, etc.

Depending on the application of heating asphalt concrete in its processing recycling technology subdivide into two large groups:

1. Hot recycling, which cannot do without heating the old asphalt concrete material to the softening temperature of the old bituminous binder. Heating is used at the stage of dismantling the ABP, in the process of restoring the plastic properties of old bitumen and when mixing granulate with fresh components in the manufacture of asphalt concrete mixture for laying instead of the removed canvas.
2. Cold processing methods ( cold recycling), during the implementation of which there are no thermal effects on old stuff and the components of the fresh mixture.

The realities of road repair practice are such that most often combined versions of the named methods are used.

For example, hot processing of asphalt concrete not so long ago was identified with work in stationary plant conditions in an area with a developed industrial infrastructure (warehouses, transport routes for the delivery of asphalt scrap and export of prepared asphalt concrete mixture, containers with bitumen, etc.).

With the advent of mobile ADPs, asphalt processing is carried out directly on the road being repaired, ensuring that all the necessary technological operations inherent in hot recycling.

Cold milling, used in the methods of cold recycling of mobile plants, has successfully "migrated" into the technological streams used at stationary ABZs.

Instead of warming up in mixers crushed pieces of ABP or granules from road milling can be mixed with emulsion additives or foamed concrete, after which they are considered fit for styling.

As an alternative to the traditional technology of ABP recovery according to the formula "milling and re-asphalting" on-site hot and cold regeneration techniques.

The first of them uses the reclamation of asphalt concrete at a stationary or mobile type plant, and the second - loosening the pavement material, processing it on site, improving the properties and laying it in the pavement pavement.

A set of thermoprofiling equipment is involved in the work consisting of an asphalt preheater, a hot recycler, also called a thermal profiling machine, and smooth-drum rollers.

Working Principles of Asphalt Concrete Plants

Process flow processing of asphalt concrete at the ABZ comprises next steps:

Hot processing at the ABZ has the following advantages:

• the possibility of continuous quality control of the components of the old UPS;
• regulation of the formulation of the mixture, taking into account the composition of the used granulate;
• the ability to use up to 80% of the old material without reducing the prescription properties of the fresh asphalt mix.

Of the shortcomings hot processing under stationary conditions, the following factors are noted:

• high costs of transportation of the dismantled coating;
• high energy consumption of drying and heating of asphalt concrete mixture components;
• the presence of carcinogenic hydrocarbons and mineral dust in smoke emissions.

Features of hot and cold methods at the work site

Hot way, also called thermal profiling of asphalt, is carried out directly at the place of repair roadbed.

For all technologies thermal profiling is characterized by the following operations:

• warming up the upper layer of the ABP;
• loosening the heated layer;
• mixing of the loosened components;
• re-styling.

Depending on the specific hot recycling technology at various stages of the technological process, operations for adding bitumen, adding plasticizers or fresh asphalt concrete mixture, etc. can be used.

Hot Onsite Asphalt Recycling Technologies have the following advantages:

• high physical and mechanical properties of reclaimed asphalt concrete;
• ease of use of technology;
• minimal wear of the cutting tool;
• preservation of the existing geometry of the coating;
• the ability to work in one lane without interfering with traffic in another lane;
• reduction in the cost of repair and installation work;
• increase in the service life of the coating;
• by almost half the time for repair work.

The disadvantages of the "hot" method include:

• environmental problems - when heated, vapors of old bitumen evaporate;
• deterioration of bitumen plasticity when the heat treatment temperature is exceeded;
• difficulties in organizing work, since the entire machine complex used in work must be in "combat" readiness.

Cold recycling works held on site, are performed in the following sequence:

Of the merits cold recycling in place note:

• low power consumption;
• ecological purity of technology;
• preservation of the integrity of the soil, the absence of its deformations;
• high-quality regeneration of the coating.

The disadvantages of this technique are as follows:

• high cost of equipment (emulsifiers, etc.);
• the need for a clear organization preparatory work and constant monitoring of the technical condition of the equipment used.

Conclusion

The use of resource-saving technologies for the use of reclaimed old asphalt concrete materials makes it possible to create an adequate replacement for a certain part of the components of the asphalt concrete mixture in compliance with the basic requirements for the quality of road surfaces.

At the same time, it is essential costs are reduced for the purchase of bitumen, energy resources and materials are saved.

With us, each client can comfortably place an order and be sure that his goods will arrive on time and in full!

Secondary building materials have a significant economic advantage over primary ones. It should also be noted that the advantages of recyclable materials are technical and aesthetic characteristics. If you are deciding the issue of inexpensive land improvement, we recommend buying asphalt crumb with delivery in Moscow, the price of which is the lowest of a number of road decks.

There are three types of this secondary material: from under the cutter, from under the crusher and asphalt chips. All three types are in approximately the same demand in the secondary building materials market. Asphalt crumb price, which compares favorably with asphalt, is an irreplaceable material in road construction. This material is used very widely in the arrangement of road surfaces that do not have strict strength requirements, such as for federal highways. Very often, a road made of asphalt crumbs can be seen at a dacha, in a garden partnership, a cottage village or in an industrial area. MSK Region is a qualified supplier of building materials. Our company has its own specialized vehicle fleet for the transportation of bulk building materials. Therefore, no matter where you need to deliver the asphalt crumb - to Moscow or in the Moscow region, we will do it quickly and efficiently.

Asphalt crumb cube prices

The above table shows the cost of material with delivery. Asphalt crumb price per cubic meter. meter with delivery in Moscow is usually purchased in bulk (in bulk). The cost of delivery of asphalt chips in Moscow and the Moscow region (Domodedovo, Mytishchi, Shchelkovo, Stupino, Podolsk, Chekhov, Lyubertsy, Odintsovo, Pushkino, Solnechnogorsk and others settlements) is calculated individually and depends on the delivery address.

Before ordering asphalt crumb or buying it for use in Moscow, Podolsk, Khimki, Dolgoprudny or elsewhere, further information will be useful.

Why is the cost of asphalt crumb so cheap?

Because dear and necessary materials have already been paid for to create the initial coverage. Pricing is based on the cost of removing, transporting and recycling the old coating. As a rule, processing and crushing occurs directly when it is removed from the road. Therefore, the price of asphalt chips is several times cheaper than the real cost of the components (crushed stone, bitumen, granite screening and sand). In addition, using this product, you effectively solve the problem of recycling building materials, which is of global importance today.

Characteristics of the constituents of asphalt crumb:

• Crushed stone for road surfaces is most often used in fine and medium fractions (up to 45 mm). Long-term operation and bringing to marketable condition leads to additional grinding of stone grains. This contributes to a good compaction.
• Bitumen is a polymerized substance obtained from petroleum products that has thermal, electrical and waterproofing qualities. Having no melting point, bitumen softens with a certain heating, after cooling it hardens and becomes solid. The most important properties for road surfaces are high adhesion and hydrophobicity of recycled asphalt and bitumen.

Granite screening (screening of crushed stone with a grain size of 0 to 5 mm) and sand.

For any business executive, a reasonable price-quality ratio plays an important role. The density of the coating with the crushed substance is much higher than that of the original components. The high resistance of crushed stone and sand is enhanced by the adhesion of bitumen. Summer heat and sunshine provide additional formation of strong bituminous bonds. This all determines the maximum durability, weather and wear resistance. The crushed compound, distributed on the road, takes the required shape, fills in holes and irregularities. The compacted secondary crushed stone and bitumen help to resist erosion and cracking of the road. When vehicles are driving, rubble, flying out from under the wheels, hits cars and creates noise. The baby does not have such disadvantages.

Application of asphalt crumb

Before ordering a car asphalt crumb at a low price (with delivery) in Moscow, you need to determine how it can be used? There are two main directions.

The first is construction. This is the construction of pedestrian and driveways, sports grounds, parking lots, zoning of the territory. The scope in this direction is limitless: courtyards, summer cottages, country roads, school and non-professional stadiums, parks and squares. Quite often it serves as a material for road repair: filling holes and cracks, strengthening roadsides.

The second is the design landscape design... Ornate paths created from this material will perfectly decorate your private property. In addition, paths made of fine asphalt are much more comfortable than gravel or crushed stones. Silver-black chips are effective in framing and highlighting flower beds, shrubs, creating an alpine slide.

How to calculate the correct amount of material required?

The material is rolled twice, that is, if 20 cm is poured, after ramming it will turn out to be 10 cm. The value of the purchased material is equal to the area of ​​the covered surface multiplied by 0.2. The result is the number of required cubic meters... Additionally, possible parameters are laid for holes and cracks.

Summer time of the year is chosen for road construction works. A dry and dense base is the key to a good road. But covering with recycled material does not imply the use of structures for loads similar to main lines. Therefore, the season is determined by the owner, but in any case not at the time when the soil (base) is frozen.

One of the most common recycled materials is asphalt chips, also known as asphalt granulates, and are used in a wide variety of construction and refurbishment jobs.

This material is obtained by grinding the old asphalt pavement removed during the replacement or repair of the roadway. Thus, asphalt crumb consists of bits of bitumen and fine crushed stone from three to five millimeters in diameter, in addition, it may contain traces of sand or other elements.

Use of asphalt crumb

Due to the inexpensive price, ease of use, as well as the fact that the crumb, as a product obtained by processing, causes relatively less harm to the environment, the range of its use is extremely wide and includes almost all spheres of human economic activity:

Due to the widespread use of this material, as well as the availability of many other options on the market, consumers, trying to find the most acceptable option for themselves, often ask the question of how much a cube of asphalt chips costs. Below in the abstract form are the main reference characteristics of this material, including answers to questions such as how much 1 cubic meter of asphalt crumb weighs and how many cubes fit in a KAMAZ or dump truck.

• The average price of asphalt chips in Moscow is $ 12-14, in the regions it starts from $ 10;
• 1 cube of asphalt crumb can weigh from 1500 to 1900 kilograms, depending on its composition;
• Accordingly, about 12 cubic meters will fit into the body of an average KAMAZ;

The consumption of crumbs per m2 with a layer thickness of 20 centimeters is approximately 400-600 kilograms.

Laying technology

1. First of all, the base for asphalt crumb is prepared. The terrain is leveled, large debris is removed: cobblestones and scrap metal. It is quite possible to skip this point if the terrain condition is acceptable for this purpose.
2. Optionally, the surface is primed using a bitumen emulsion of asphalt crumbs for better adhesion in the future. Its consumption is about one liter per square meter;
3. Laying crumbs on the surface, compaction of the laid layer. This can be done both with specialized equipment and independently. It is worth remembering that the compaction coefficient of asphalt crumb, depending on the composition, reaches a value of 2 units, which means that during rolling, the thickness can be reduced by up to two times and it is imperative to include this factor in the calculations!
4. Impregnation of bitumen emulsion of asphalt crumb. This will further strengthen it and increase its service life. Consumption of about 0.5 liters per m2.

Laying asphalt chips with your own hands is not too different from the technology described above. The only difference is that you will have to lay it out yourself with the help of shovels, and roll it up with cars. Difficulties may arise with how to melt asphalt crumb: without the use of technology, this is not only laborious, but also flammable. You can melt the crumb over an open fire in a metal container of sufficient size. Be sure to have a fire extinguisher with you to extinguish a possible fire!

Pros and cons of using asphalt chips

To begin with, let's mention the environmental aspect of the use of asphalt crumb. Many people, from among those who will ennoble country cottage area, having children and animals in the family, is interested in whether asphalt crumb is harmful. Despite the fact that it contains bitumen - a product of oil refining, which, accordingly, causes more harm to the environment than good, the use of crumbs in the household is more environmentally friendly than in the case of asphalt of the same volume.

According to the documentation, asphalt crumb has a hazard class 4, on a par with household waste such as old clothes and shoes.

1. A wide range of applications, covering most of the spheres of human economic activity;
2. Affordable price, which favorably distinguishes asphalt crumb against the background of crushed stone or gravel and, due to similar properties, has recommended crumb as a suitable replacement for them;
3. Long service life when used in suitable conditions for this: secondary roads and short paths and sports complexes;
4. Ease of styling. For this, it is not necessary to prepare the surface in advance, and rolling of asphalt crumbs does not imply the obligatory participation of special equipment; in order to save money, it can be done with the help of passing cars;
5. High resistance to adverse weather conditions.

The disadvantages of asphalt crumb, like any other material, exist:

1. More harmful effects on environment in comparison with crushed stone or sand;
2. The need for periodic updating of the canvas.

However, all the shortcomings are fully covered by its numerous positive qualities.

Alternative options

In addition, consumers often ask the question: which is better, asphalt crumbs or crushed stone? There is no definite answer to it, since these materials, including sand and broken bricks and concrete, usually perform the same functions. But the price of the crumb is lower, and the crushed stone has a less harmful effect due to the absence of bitumen in the composition. So the choice must be made based on circumstances and personal preference.

Summing up

Thus, crumb asphalt will be the ideal option for you if you value simplicity and ease of installation and prefer to spend extra money on yourself and your loved ones, rather than on Construction Materials... For a parking lot or driveway, playground or garage floor, this material will meet your every need!

Asphalt crumb is a material used today in road construction and road repair work. The popularity of this material is growing day by day, due to its properties and affordable cost. Asphalt crumb is obtained by artificial crushing of the asphalt pavement. Moreover, as a rule, the old, worn out asphalt surface, which is no longer suitable for driving, is subjected to grinding.

To remove old asphalt pavement, use special equipment, which is called a cutter. This is a road technique that, under the control of specialists, cuts the top asphalt layer from the road, and immediately crushes it, turning it into asphalt crumbs. This process is called road milling and it is very relevant when overhaul road or its restoration.

In fact, asphalt crumb is a secondary raw material, as it is the result of recycling old asphalt pavement. This can explain its low price.

Perhaps the main advantage of asphalt crumb is that it has all the properties of asphalt. Its small particles are easy to work with, and asphalt chips are easy to compact and tamp. And the bitumen particles that it contains make it possible to create additional lighting on the roadway at night, due to its ability to reflect the headlights of cars passing along the road.

Our prices.

The cost of asphalt crumbs from 955 rubles m3 with delivery in Moscow.

Currently, much attention is paid to the improvement of the territory, for example, asphalting roads. At the same time, preference is often given to the most economical options.

The secondary material used in road construction - asphalt crumb - is formed by crushing cracked asphalt with a special machine. In this case, the method of cold milling or crushing of the removed road surface is used, which is called asphalt scrap. The result of these procedures is a mixture, which includes crushed stone, sand, bitumen residues. The technological value of asphalt crumb is due to the presence of bitumen in it, which enhances intergranular bonds, thereby improving the physical and mechanical characteristics of the roadway, in the construction of which this material was used.

Ways of using asphalt crumb:

• Production of cold AGB-mixes (asphalt-granulo-concrete mixes) - asphalt crumb is a part of this material, which is used in cold regeneration. It should be noted that this technology involves the restoration of damaged roads by milling outdated pavement;
• The production of hot AGB-mixtures - asphalt crumb, which can be ordered from our company, is involved in the hot regeneration process. Distinctive feature This technology is the preheating of asphalt concrete before milling. This way you can update the top layer of the road;
• Construction of a base characterized by low strength properties - this procedure is performed if necessary to asphalt a small area;
• Creation of temporary road surfaces, technological passages and other structures, which are characterized by a low traffic load. In this case, the material used retains a loose structure throughout the entire operational period.
