Processing of asphalt crumb. Use of recycled asphalt concrete for road construction. The use of asphalt chips

Owners of suburban areas know for sure how terrible the road is often outside the city. For example, not in all even cottage settlements, builders equip high-quality roadbeds. 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 the same 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 must have certain positive sides as well as cons.

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 gravel, not to mention more expensive coverage from asphalt concrete.
   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 convenient 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.

In the field of repair and reconstruction of the roadway, the effectiveness of the use of secondary asphalt concrete. Due to the content of bitumen, stone, plasticizers in such material, asphalt regeneration is expedient not only from an economic, but also from a technical point of view. Additionally, such an event saves energy and resources. Secondary materials attracted the attention of builders because the cost of the bitumen and mineral components used in them is quite high.

Stages of application of asphalt concrete:

• specialized equipment removes the worn layer from the base;
• transportation of the obtained material to the asphalt concrete plant;
• heating the secondary product, in some cases it is mixed with a fresh portion of bitumen or other raw materials.

This process can take place not only in the conditions of a stationary technical base of the plant, but also when using mobile equipment. The described process of hot processing of recycled materials is not the only one, it is also widely used. cold way. To do this, at the factory, individual pieces or other material obtained after milling the roadway are carefully crushed and mixed with fresh emulsion. The resulting material is used to create roads with a low level of congestion, for example in villages.

In our country, it is hot processing that is widely used, which is carried out using equipment from various foreign manufacturers. Such batch plants are often produced mobile, which reduces the cost of resources and time, excluding the participation of the plant from the process.

ABZ "Bernardi" with a system

asphalt recycling

Particularly noteworthy is the Italian company BERNARDI, which creates state-of-the-art recycling facilities. With the help of its advanced dryer, it is possible to regenerate up to half of the worn mixture. At the same time, costs remain very low. The technology used in this unit is called "RED" and over the years of use has proven itself to be one of the best.

Another technology is used by the Chinese brand D&G Machinery. This company uses time-tested classical technologies for the regeneration of waste road construction materials. All installations produced by the brand can be divided into two main categories. The first is equipment with a parallel drying element, which guarantees the processing of a large percentage of recyclable materials (50% or more). This technique requires a significant investment. The second option is a recycling ring, which is an order of magnitude cheaper, but it can be used to recycle no more than 35% (usually even less) of asphalt concrete.

Before loading into such units, the raw material is crushed in impact rotary, jaw or cone units (more details). To simplify the task of grinding high-strength material and speed up this operation, it is saturated with water. It is preferable to carry out crushing in a cold or moderately warm environment, the temperature of which does not exceed 15 degrees Celsius. If we are not talking about lumpy material, but obtained by milling, it is not necessary to grind it - just add it to fresh, thoroughly dried mineral raw materials in a special drum.

Technologically, the asphalt recovery process proceeds as follows:

• fresh mineral base is dosed and placed in a drum-type heater;
• old materials are loaded into the same container: asphalt dust, bitumen fragments, crushed lumpy raw materials;
• all this is heated to strictly defined temperatures (to avoid the rapid aging of the mixture) and mixed with a fresh portion of bitumen or plasticizer;
• after preparation of the mixture, it is unloaded into a skip-type lifting device, transported to the bunker of finished materials.

The installation is controlled by a trained operator at all stages of the restoration of the building mixture. In addition to the heater, the same equipment is involved in this process as for other types of asphalt concrete complexes. This makes it easy to set up the process of regeneration of asphalt concrete.

One of the most common recycled materials is crushed asphalt, also known as asphalt granulate, which is used in a wide range of construction and repair jobs.

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.

Do-it-yourself asphalt crumb laying 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 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 open fire V metal container 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. To do 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 harmful effect on environment compared to gravel 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 be an ideal option for you if you value simplicity and convenience in laying and prefer to spend extra money on yourself and your loved ones, rather than on Construction Materials. For a parking lot or driveway, sports field or garage floor, this material will meet your every need!
