Processing of asphalt crumb. Utilization of scrap asphalt and asphalt concrete pavements. Asphalt scrap and granulate

The asphalt concrete pavement of the autobahn is constantly exposed to mechanical loads from.

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

Internal stress and strain roadbed 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.

To ensure that the quality of the roadway meets safety requirements traffic(art. 12 federal law dated December 10, 1995 No. 196-FZ as amended on July 26, 2017 "On Road Safety"), road construction organizations are removal of worn and damaged layers asphalt concrete pavement (APC) and replacing them with new layers.

The volumes of annually removed old ABPs in each major city of the Russian Federation amount to tens of thousands of tons, and in general, for Russian highways, annually over a million tons dismantled asphalt concrete.

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

The regeneration of the dismantled ABP is aimed at restoring and improving the technical and operational characteristics of the asphalt concrete material in order to reuse it for asphalting autobahns or other road repair work.

After the expiration of the service life of the pavement in its composition up to 90% of useful weight is saved 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 it up.

Road pavements with ABP are the most common designs of autobahns of all categories.

Above is scheme of the so-called "road pie"- multi-layer pavement with a mandatory asphalt concrete pavement with a thickness of at least 15 cm.

GOST 9128-2013“Asphalt concrete mixes…” defines the composition of asphalt concrete mixtures (clause 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 rolling with rollers.

It is necessary to distinguish between concepts asphalt and asphalt concrete used in road construction practice:

1. Asphalt is astringent organic matter natural or artificial origin 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 oil fractions and is little different from ordinary tar, for which the ancient Greeks called it mountain tar.
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 traditional asphalt pavement.

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

This gave grounds half a century ago, on the basis of extensive research in the USA, the USSR, European countries and China, to adopt the concept of 100% suitability road asphalt concrete pavement for recycling and reuse.

Modern technologies for the regeneration and recycling of asphalt concrete pavements represent the processing of ABP worn out during operation, bringing its technical indicators and physical and chemical characteristics to the required level.

The use of dismantled old asphalt concrete allows you to do this with minimal consumption of new binders and inert fillers.

Removing end-of-life material

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

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

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

So far in small areas use manual ways opening and removing asphalt using tools such as:

• impact pneumatic tools;
• cutting installations;
• crowbars;
• kylo;
• sledgehammers;
• picks.

On large areas Removing the UPS without specialized equipment is no longer enough. Brigades with jackhammers and shovels were replaced by mini excavators with hydraulic breakers.

Serious competition to traditional methods of removing the roadway is presented by modern road milling cutters, equipped with rotating milling drums to cut through the old asphalt concrete to the required depth.

The width of the cut lane on the road when the coating is removed depends on the width of the drum and varies from 350 mm to 2200 mm.

The steel teeth of the drums cut off the required 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 concrete mixture or reclaimed asphalt concrete.

Layer milling The roadbed is performed in two different ways:

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

Each milling method has its advantages and disadvantages.

Hot milling

This method for removing ABP was introduced before cold milling was introduced.

With the help of mobile infrared burners running on gas (propane-butane mixture) or on kerosene, asphalt warms up and softens.

This helps to reduce the amount of effort that must be expended to destroy the dismantled coating.

disadvantages hot milling are the following circumstances:

• high cost of used fuel resources;
• the risk of fire of equipment and the risk of burns to personnel;
• the destroyed asphalt material sticks together, making it inconvenient to re-use;
• when stored in piles at the asphalt plant warehouse, pieces of milled asphalt cake in hot weather, which forces them to be poured with sand or mineral powder.

When choosing hot milling, the priority motive is repair work speed, because the heated ABP is cut 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 hard state.

Benefits this technique are the following factors:

• the invariability of the coating structure, which makes it possible to use the removed material as part of the prepared asphalt concrete mixture;
• when stored in piles, pieces of milled asphalt concrete do not cake;
• economy of the milling process.

Asphalt scrap and granulate

The dismantling of the old ABP leads to the formation of pieces of asphalt concrete of various sizes, called asphalt concrete scrap.

The composition of such waste - scrap - remains the main components of asphalt and asphalt concrete pavement - crushed stone, sand and bitumen residues.

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

Piece sizes asphalt are not standardized, however, in the practice of separating asphalt blocks usually divided into three conditional groups:

• small waste, the size of which does not exceed 20 cm;
• average scrap with element sizes of 15-40 cm;
• large blocks larger than half a meter.

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

• strength to mechanical static and dynamic loads;
• resistance to atmospheric moisture and chemically active substances;
• resistance to sudden temperature changes;
• the possibility of further grinding 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 receive asphalt concrete granulate(hereinafter - ABG) and asphalt baby which are in high demand. Average density ABG - from 2100 to 2200 kg / m3.

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

Due to the growing demand for ABG in road repair work 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 road pavement.

On Russian market building materials scrap asphalt price varies between 100-300 rubles / cu. m, while the secondary ABG is offered at a price 500-1500 rub. per ton.

Recycling and regeneration

In the world practice of road construction works on the reconstruction of autobahns, 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 together the end results of completely different technological concepts in their essence.

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."

With regard to the reconstruction of highway pavement regeneration means the restoration of their technical and operational qualities:

• continuity,
• traffic,
• accident and safety coefficients, etc.

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

Among these properties:

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

Reuse of the material of the old UPS, experts call English word"recycling", meaning recycling- reuse, return to circulation, rework / processing for useful use.

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

ABP recycling algorithm

For the technical implementation of the recycling of old asphalt concrete in order to use it as the top layer of the road surface the following work is being done:

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

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

1. For a new asphalt mix obtained from a recycling process, preliminary design is required 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 regimes, preventing the start of evaporation of light fractions from the binder composition and its burnout, which can occur when the flash point of bitumen is exceeded (180-220 degrees C for viscous and 45-110 degrees 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.

Ways to reuse asphalt concrete waste

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

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

Depending on the heating application asphalt concrete during 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 ABP dismantling, in the process of restoring the plastic properties of old bitumen and when mixing granulate with fresh components in the manufacture of asphalt concrete mix for laying instead of the removed canvas.
2. Cold processing methods ( cold recycling), in the implementation of which there are no thermal effects on old stuff and on the components of the fresh mix.

The reality of road repair practice is that most commonly used combined options named methods.

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

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

Cold milling, used in mobile plant cold recycling techniques, has successfully "migrated" to process flows used in stationary asphalt plants.

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

As an alternative to the traditional technology for the restoration of ABP according to the formula "milling and re-asphalting" are hot and cold regeneration techniques at the roadworks site.

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

The work involved a set of thermal profiling equipment, consisting of an asphalt heater, a hot recycler, also called a thermal profiler, and smooth rolled rollers.

Principles of operation of asphalt concrete plants

Process flow asphalt concrete processing at asphalt concrete plant comprises following steps:

Hot processing at the asphalt plant has the following advantages:

• the possibility of constant 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 possibility of using up to 80% of the old material without reducing the prescription properties of the fresh asphalt mix.

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

• high costs for the transportation of the dismantled coating;
• high energy consumption of drying and heating components of the asphalt mix;
• 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 repair site roadbed.

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

• heating of the upper layer of ABP;
• loosening of the heated layer;
• mixing loosened components;
• re-laying.

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

On-Site Asphalt Concrete Hot Processing 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 on one lane without obstructing traffic on the other lane;
• reduction in the cost of repair and installation work;
• increase the service life of the coating;
• reducing the time for repair work by almost two times.

The disadvantages of the "hot" method include:

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

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

Of the merits cold recycling on site note:

• low energy consumption;
• ecological purity of technology;
• maintaining the integrity of the soil, the absence of its deformation;
• high-quality regeneration of the coating.

The disadvantages of this technique are the following:

• 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.

Asphalt (asphalt) crumb is recycled asphalt. The crumb is similar to crushed stone, it is used for backfilling of the road, parking, platforms. Asphalt crumb is obtained by cutting off the asphalt pavement using a road milling machine. The bitumen particles that are present in the asphalt crumb make the surface more durable after compaction. Due to the large amount of bitumen and crushed stone in the composition of the crumb, it is very well rolled by a road roller, vibrating plate or car wheels. A road, a parking lot made of asphalt crumb will last longer than crushed stone because asphalt crumb is less exposed to precipitation, is not washed out by rain, and does not form dust, such as crushed limestone. Asphalt crumb is also used as a base under asphalting, patching roads, for overhaul roads, backfilling of roadsides. Our company "MskDor" offers to buy asphalt crumb at a low price per m3 from under the cutter or from under the crusher (crushed crumb), it is possible with delivery and pickup from the site, sale in Moscow and the Moscow region.

Asphalt crumb sizes: from 0.5 cm - 4.5 cm, small enough to fill roads for cars or paths in the country.

Asphalt crumb application:

• Road construction, for cottages and country roads
• Parking device, car parking
• Laying asphalt crumbs on the road, in the garage
• Backfilling of roads and roadsides with asphalt chips
• Repair of a country or country road, backfilling of paths in the country

Before laying asphalt crumb or a road in the country, you must first understand how much asphalt crumb is needed. To do this, you need to calculate the area of ​​\u200b\u200bthe road and multiply by the thickness of the layer.

Transport infrastructure is one of the most important systems of any state. With its help, goods are exchanged between cities. This is how the products most likely arrived at your nearest store. Therefore, keeping the road in the best possible condition is necessary to meet all transport needs.

The first builders of roads under the understanding that we know today were the Romans. During the time of the Roman Empire, they were concerned about the need to build trade routes to their capital from all over the empire. There is a saying that confirms this: "All roads lead to Rome." This can be seen on the historical map.

It is worth noting that they approached this issue thoroughly, even after thousands of years there are well-preserved sections of it. We need to thank the designers who pointed out the need to create a strong foundation. It provided reliability for ages. From above, either smooth slabs or a scattering of small stones were usually placed.

In our time, the process of building roads has become more technologically advanced. This is done both to give a smooth surface and increase the life of the blade. Engineers calculate all the factors that affect the service life. This must be taken into account, since serious loads act on the road surface around the clock. In summer high temperatures they simply “melt” the asphalt, as a result of which a track from the wheels appears. During the first frosts, the water that penetrated the cracks freezes and turns into ice, and, as is known from school course Physics ice has a larger volume than water. Therefore, the water literally tears the road apart. Another advantage of modern roads is the speed of repair. A defective place can be repaired in just one hour.

The process of sorting asphalt concrete scrap

During the repair work with the replacement of the roadway, asphalt concrete waste is generated different size. This sometimes complicates the recycling process, since not all construction machines able to grind large blocks of asphalt. For this, a conditional classification of sizes was invented. It is called conditional due to the fact that in GOST there is no column with an exact indication of the values. There are usually three groups of pieces of recycled asphalt:

• Small fragments - up to 150mm;
• Medium debris - up to 400mm;
• Large scrap - from 400mm.

Perhaps these conventions were not documented due to the fact that most often the workers themselves have to grind the fragments to the required size on the site of the repair work.

Natural asphalt is a mixture of bitumen with various minerals.

Recycling and further use of asphalt scrap

The concept of recycling asphalt scrap implies only its processing. The material is very durable, it has no limit on the number of reuses. So just throw away old asphalt to a landfill would not be the most rational solution.

Use in construction

Asphalt scrap is a fairly versatile material in construction. With it, you can strengthen roads that do not have a hard surface or simply fill in holes.

Much more right decision there will be a reuse of the old material in the laying of a fresh roadbed. To achieve this goal, a special installation called a recycler is used, inside which asphalt is processed. More specifically, it heats the mixture and mixes it until it is homogeneous. Approximately, as a concrete mixer. To achieve the most quality product must be strictly observed temperature regime. Externally, the installation has an unremarkable appearance: a barrel painted in Orange color, which is installed on the chassis from the trailer. There are many models of such stations, up to self-propelled ones, but the type described is the most common. This allows it to be mobile enough that it can be used in the narrow streets of the city.

Prices for asphalt concrete scrap

Asphalt production waste has a fairly low cost in the construction market. For example, one ton of raw waste will cost only 200 rubles. By this is meant only the removed lumpy asphalt, usually large sizes. Asphalt crumb is much more expensive, about 1000 rubles. This is logical, since it is already a full-fledged repair and construction material.

There is also the concept of asphalt granulate, it differs from crumbs in more thorough preparation in the form of crushing, as well as screening in specialized installations. All information is prescribed in detail by GOST R55052-2012.

Keep in mind that the supplier may vary the price of granulate, both up and down, depending on such factors:

• seasonality;
• Volumes of purchased material;
• The quality of the product provided.

Another cost line is the transportation of freshly acquired material to the place of work. This fact once again proves the wisdom of recycling old asphalt into new one.

Conclusion

Thus, we found out the importance of recycling and reuse waste. Especially if this process is quite simple and does not require the infusion of a large amount Money. We can only hope that in the near future this practice will be extended to other industries.
