Asphalt crumb with delivery. Utilization of scrap asphalt and asphalt concrete pavements

Owners of suburban areas know for sure how terrible the road is often outside the city. For example, not all cottage settlements, builders are equipping a high-quality roadbed. As a rule, everything is done with ordinary rubble or even just a compacted dirt road. In this article, we will try to talk about how to lay asphalt crumb.

Using recycled asphalt?

Asphalt crumb, you can often find the name asphalt granulate - the most optimal material in terms of quality and cost, in comparison with a similar type of crushed stone in a gravel layout. This material is used in the repair of road bases and coatings, the production of which is associated with the milling of old roads, where bitumen and crushed stone are included.

Undoubtedly, such material should have certain positive aspects, as well as disadvantages.

Pros:

1. It has long been confirmed by experts that roads paved with crumbs are more durable and resistant to stress than the classic pavement made of ordinary crushed stone with gravel.
   2. The cost is an order of magnitude lower than the cost of shipping crushed stone, not to mention the more expensive asphalt concrete pavement.
   3. Simplicity of works. Crumbs do not require bulky equipment, such as road rollers. The granulate rolls perfectly under the weight of passing cars, but it should be understood that in this case waves may appear. Therefore, it is worth carefully ramming so that ruts do not form over time.

Minuses:

Taking into account all the features, only one negative side comes to mind, this is that over time, such a coating requires periodic backfilling or leveling with a special grader. Such a coating has certain features, it also breaks down during a period of temperature difference and excessive moisture ingress.

Proper laying of asphalt granulate

Those who have decided to restore or build a road to their home or simply make a comfortable platform in front of the gate should understand some important features. These features directly determine how long your road will last before the first repair.

1. Determine the minimum tonnage of vehicles that will move along your section of road.
2. Consider in advance what type of foundation will be laid under the asphalt crumb. For example, the choice may consist of sand, cement slabs, gravel, crushed stone. Also determine the current state of the canvas, whether there are potholes, pits, cracks, ridges, waves.
3. Calculate the amount of money that you are willing to donate to the road, taking into account all subsequent costs for possible repairs.

Asphalt laying technology

Before directly laying the crumbs, you need to take care of the masonry surface itself.

1. We determine the area of ​​work and carry out high-quality marking, taking into account, among other things, the location of communications, the growth of plants, trees, etc.

2. We buy material, here it is worth adhering to such parameters based on your site, given that per 100 sq. m. you will need about 14 tons of the crumb itself.

3. It is advisable to take a skating rink, usually companies involved in the production and delivery of crumbs practice the provision of related equipment rental services.

4. It is desirable to remove a soil layer of about 30 cm, with a slope of 5-6 mm per meter. This will avoid flooding adjacent areas during rains. After removing the soil, it is recommended to lay geotextiles.

Important. Geotextiles will help to avoid asphalt subsidence, this is especially applicable to roads on which heavy equipment will periodically move. In addition, geotextiles in rural road conditions help to reduce the use of crumbs.

5. We immediately process the edges of the dug ditches, you can also install curbs, if provided for in the estimate.

6. After the work done, you can start laying the crumb itself directly.

Advice. Wanting to save money, you can buy a crumb in advance, for example, from October to April, when the cost of the material is much lower.

How to lay asphalt granulate correctly

The laying process itself is incredibly simple and even the most distant person from construction affairs can handle it. It is only important to get a couple of three assistants who will be useful in this matter.

The process consists of several stages:

1. It is necessary to scatter the crumb approximately evenly over the area. Consider in advance how many layers of crumbs are expected based on your conditions.

Advice. It is better to make two separate layers, each of which will be 6-8 cm. They need to be individually rammed, in between you can use a lining, or you can not, depending on the expected loads.

2. After the crumb has been leveled, you can start tamping. Of course, it is better to use a skating rink, it is simple to operate and does not require special skills. Compaction should be until complete hardening.

3. The last step can be omitted, but it serves as an additional guarantee of the durability of the coating. This is pouring crumbs with bitumen emulsion, of course, these are additional costs, but they are offset by a delayed future repair.

Sale of asphalt crumb from 500 rubles. for 1 m3. Asphalt, otherwise asphalt crumb, is a loose material for the road, similar to crushed stone, which is cheap, after compaction it looks like asphalt. According to its characteristics, asphalt crumb is even superior to other materials somewhere, as it is perfectly rolled and compacted by a roller.

Asphalt crumb is obtained as a result of a cut of old asphalt from the road. The use of asphalt crumbs is very diverse: to equip a drive - an exit to a house or a plot, to raise and lay out a road from crumbs in the country, for laying and backfilling roads in SNT, territory, parking for a car. You can buy asphalt crumb in Moscow, the Moscow region both with delivery and with laying, possibly for self-delivery: for giving, parking, paths in the country, roads, garages, leveling the road, filling driveways and the street. To order delivery, please contact our company "RossDor" - you can buy fresh crumbs from under the cutter in the morning or at night of your choice.

Asphalt crumb price for 2019

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 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

Dismantling of the old ABP leads to the formation of pieces of asphalt concrete 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. The advantages of asphalt scrap are the following qualities:

• 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 concrete 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 conditions , 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 at the asphalt 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.

In contact with

One of the most common secondary materials, obtained by processing, is asphalt chips, also known as asphalt granulate and used in a wide range of construction and repair work.

This material is obtained by grinding the cold milling of the old asphalt pavement taken during the replacement or repair of the roadway. Thus, asphalt crumb consists of particles of bitumen and small gravel from three to five millimeters in diameter, in addition, it may contain traces of sand or other elements.

The use of asphalt

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

Due to the wide use of this material, as well as the presence of many other options on the market, consumers, in an attempt to find the most suitable option for themselves, often ask how much a cube of asphalt chips costs. Below, in the thesis form, the main reference characteristics of this material are given, including answers to such questions as how much 1 cube 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 chips can weigh from 1500 to 1900 kilograms, depending on its composition;
• Accordingly, about 12 cubic meters will fit in the body of an average KAMAZ;

The crumb consumption per m 2 with a layer thickness of 20 centimeters is approximately 400-600 kilograms.

Laying technology

1. First of all, the base for the asphalt crumb is prepared. The area is leveled, large debris is removed: cobblestones and scrap metal. This item may well be skipped if the condition of the terrain is acceptable for the purpose.
2. The surface is variably primed using a bitumen emulsion of asphalt chips for better adhesion in the future. Its consumption is about one liter per sq.m.;
3. Laying out crumbs on the surface, compacting the laid out layer. This can be done both with specialized equipment and independently. It is worth remembering that the compaction coefficient of asphalt chips, depending on the composition, reaches a value of 2 units, which means that during rolling, the thickness can decrease up to two times and be sure 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 is about 0.5 liters per m 2.

Asphalt paving with my own hands 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 with cars. Difficulties may arise with how to melt asphalt chips: 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 chips. Many people, from among those who will ennoble country cottage area, having children and animals in the family, is interested in whether asphalt chips are 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 economy is more environmentally friendly than in the case of asphalt of the same volumes.

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

1. A wide range of applications, covering most of the areas 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 the crumb as a suitable replacement for them;
3. Long service life when used in suitable conditions for this: minor roads and paths of short length and sports complexes;
4. Ease of installation. For this, it is not necessary to prepare the surface in advance, and the rolling of asphalt chips does not imply the mandatory 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.

Disadvantages of asphalt crumb, like any other material, exist:

1. More environmental impact than 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.

Alternatives

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

Summing up

Thus, asphalt crumb will become for you ideal option if you value simplicity and convenience in styling and prefer to spend extra money on yourself and your loved ones, and not on Construction Materials. Whether in a parking lot or driveway, sports field or garage floor, this material will meet your every need!
