Application of asphalt crumbs. High-quality laying of asphalt chips Technology of laying asphalt chips

Asphalt chips are classified as recycled building materials, the advantage of which is their attractive cost. When compared with crushed stone, the price of crumbs is almost three times lower. At the same time, in some areas it becomes a full-fledged substitute for crushed stone, and sometimes even surpasses its qualities.

We are counting required quantity and lay it down
Asphalt crumbs are laid either manually using shovels or with an excavator. A dump truck first delivers it to the installation site and pours it out in several portions evenly over the site that will be paved. The territory must be prepared in advance - cleared, removed all unnecessary, leveled as much as possible.

The layer should be approximately 15-20 cm - this is enough to form a dense coating. The final stage is rolling. If the crumbs are laid on country roads, they do not resort to the help of an excavator - compaction by the wheels of passing cars is enough.

Quantity required material It is calculated very simply: the area of ​​the road to be filled needs to be multiplied by 0.2. The resulting figure shows the quantity cubic meters material to create a layer 20 cm thick. It must be borne in mind that the thickness will be halved after rolling and will become 10 cm, so there is no point in saving and making the initial layer less than 15 cm. It is important to take into account the so-called errors - holes, potholes, irregularities, backfilling of which will require additional crumbs. Therefore, to the obtained result you need to add a little more material as a reserve.

Working with crumbs is so simple that you can do it without large quantity people to pave the roadway. Of course, provided that the area of ​​the plot is not huge - up to 100 m2. The skating rink can be rented, and it is easy to operate it yourself. It is necessary to roll the crumbs until they harden. If possible, it is advisable to fill the top with a bitumen mixture.

Advantages over crushed stone and sand
In summer when high temperatures air, asphalt chips rolled into a monolith together with bitumen inclusions form a very strong bond. In addition, it does not cause harm to the car body, even if it flies out from under the wheels, which cannot be said about crushed stone.

Another advantage over crushed stone and sand is stronger compaction. After some time, the asphalt crumbs become similar to the asphalt of city roads - as if appearance, and by quality characteristics. It’s not for nothing that it’s called cold asphalt or black crushed stone. In addition, the susceptibility to the destructive effects of water is very small, so the service life of such a coating is long.

The use is gaining momentum, especially among owners of private houses with their own driveways. According to some forecasts, such popularity may provoke an increase in price by 20-30%, but so far the price remains the same low.

One of the most common recycled materials obtained through recycling is asphalt chips, also known as asphalt granulate and used in wide range construction and repair works.

It turns out this material by cold milling the old asphalt surface removed during replacement or repair road surface. Thus, asphalt chips consist of particles of bitumen and small crushed stone from three to five millimeters in diameter, and may also contain traces of sand or other elements.

Using asphalt chips

Due to inexpensive prices, ease of operation, as well as the fact that crumbs, as a processed product, cause 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 widespread use of this material, as well as the presence of many other options on the market, consumers, trying to find the most suitable option for themselves, often ask the question of how much a cube costs asphalt crumbs. Below, in abstract form, are the main reference characteristics of this material, including answers to questions such as how much 1 cube of asphalt chips weighs and how many cubes fit in a KAMAZ or dump truck.

• The average price of asphalt crumbs in Moscow is $12-14, in the regions it starts from $10;
• 1 cube of asphalt crumbs 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 crumb consumption per m2 with a layer thickness of 20 centimeters is approximately 400-600 kilograms.

Laying technology

1. First of all, prepare the base for the asphalt chips. The area is leveled, large debris is removed: cobblestones and scrap metal. It is quite possible to skip this point if the terrain conditions are acceptable for this purpose.
2. Variably, the surface is 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 crumbs on the surface, compacting the laid layer. This can be done either with specialized equipment or independently. It is worth remembering that the compaction coefficient of asphalt crumbs, depending on the composition, reaches a value of 2 units, which means that when rolling, the thickness can be reduced by up to two times and be sure to include this factor in the calculations!
4. Impregnation of bitumen emulsion of asphalt crumbs. This will further strengthen it and increase its service life. Consumption is about 0.5 liters per m2.

Laying asphalt chips 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 using shovels, and roll it away with cars. Difficulties may arise with how to melt asphalt crumbs: without the use of technology, this is not only labor-intensive, but also flammable. You can melt the crumbs over an open fire in a metal container of sufficient size. Be sure to have a fire extinguisher with you to put out a possible fire!

Pros and cons of using asphalt chips

First, let's mention the environmental aspect of using asphalt chips. Many people, from among those who will ennoble country cottage area Having children and animals in the family, I am wondering whether asphalt crumbs 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 on the farm is more environmentally friendly than in the case of asphalt of the same volumes.

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

1. Wide range of applications covering most areas economic activity person;
2. Affordable price, which makes asphalt crumbs stand out against the background of crushed stone or gravel and, due to similar properties, has recommended the crumbs as a suitable replacement for them;
3. Long service life when used in suitable conditions: secondary roads and short paths and sports complexes;
4. Easy to install. To do this, it is not necessary to prepare the surface in advance, and rolling asphalt chips does not necessarily require the 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 chips, like any other material, exist:

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

However, all the shortcomings are completely offset by its numerous positive qualities.

Alternative options

In addition, consumers often ask the question: which is better, asphalt chips or crushed stone? There is no definite answer to this, since these materials, including sand and broken brick and concrete, as a rule, 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. So you need to make a choice based on circumstances and personal preferences.

Let's sum it up

Thus, asphalt crumbs will become ideal option if you value simplicity and ease of styling and prefer to spend extra funds on yourself and your loved ones, and not on Construction Materials. For parking or driveway, sports ground or garage floor - this material will satisfy any of your needs!

Many people have seen how they put asphalt on the roads with the help of . But there is technology cold styling, which allows you to lay asphalt on top of an existing surface. This coating can be made from old concrete or asphalt, which has already cracked and lost its original appearance.

If you do it on top using a special tamper, then this is a rather long and labor-intensive process of work. Therefore, experts recommend laying the asphalt surface in at least two layers using vibrating plates. This is precisely the reason why professional renovators do not advise laying asphalt on bare ground.

Special material for laying cold asphalt is sold in bags that are packaged at twenty-five kilograms. One bag is enough for square meter, if we take a thickness of no more than two tens of centimeters. To prime the old coating, bitumen emulsion is used, which can also be purchased at a hardware store.

Of course, before starting work, you need to tidy up the surface - the old coating. This is where bitumen emulsion is needed. Using a special brush, it is applied evenly over the entire surface. Then all the cracks and dimples that lead to unevenness are sealed. In this state, the surface should be left for a couple of hours so that the entire coating dries.

The next stage is opening the bags and pouring asphalt onto the prepared surface. Use a rake to level it evenly.

Of course, you cannot immediately fill the entire required area with asphalt, so it is better to divide it into parts and fill it one meter at a time. At the same time, we should not forget that everything needs to be compressed using a tamper. If lumps have formed, you need to crush them using a shovel or the back of a rake.

When filling the area, each square meter must be measured using a level. This will make the surface more even and avoid the formation of puddles, which can lead to cracks and holes.

To compact the asphalt, you can use a special garden tool. ice rink. To avoid unevenness, it must be sprayed with water.

Finally the path is ready. You can walk on it literally the same day, but it is better to carry heavy loads on it a few days after laying asphalt.

Roads are an eternal problem and the Achilles heel of our country. There are a lot of roads in Russia, and the road network includes not only federal highways, but also local roads, all kinds of rural roads and temporary roads, on the site of which it is only planned to build a permanent highway.

Every year huge amounts of money are allocated for the construction and repair of roads, and every year we hear that this is just a “drop in the ocean.” Road repairs are inevitable, but you need to approach them wisely, because even a small budget can be spent so that the price-quality ratio is optimal. It’s not for nothing that they say that “savings should be economical.” This means that you need to treat everything you have with care. For example, old asphalt, which is removed during road repairs in order to put a new road surface in its place, can be reused by making asphalt crumbs from it http://vikko-td.ru/. This material began to be actively used not so long ago, but has already become popular and in demand.

The VICCO company specializes in the supply of recycled materials in St. Petersburg and the region. Among the range of recycled materials supplied by the company, there is asphalt chips. In this article, specialists from the VICKO company http://vikko-td.ru/ will tell you what asphalt crumbs are, and will also share several tips on laying this material.

Asphalt crumbs are modern material, which is a recycled product asphalt pavements and suitable for road construction different quality. In addition to construction, asphalt crumbs can be used to fill roads in the internal territories of holiday villages. Such roads are subject to less stringent requirements than roads with high traffic loads, so asphalt chips will perform their function properly.

It must be said that the asphalt crumb itself, as well as its installation, will cost much less than laying a new asphalt surface, and the quality will be lower. high level. All this is due to the fact that asphalt crumbs retain almost all the basic properties of an asphalt pavement. In particular, the composition asphalt crumbs includes bitumen, which is a binding and at the same time a sealing element that extends the life of the road.

The undoubted advantage of asphalt chips is that, if desired, it can be laid on our own, without hiring a whole team of workers for this, however, if we are talking about small area, because otherwise it would be better to entrust the work to professionals, for example, contact the VICCO company. If you nevertheless decide to carry out the work of laying asphalt chips yourself, then adhere to the following plan.

To begin, determine the area of ​​work and order asphalt chips; the approximate consumption of this material will be about 15 tons per 100 sq.m. You will also need a roller whose weight will not exceed 10-14 tons. Such a skating rink, as a rule, can be rented from companies that supply asphalt crumbs. Now you can proceed directly to the process itself.

Before laying asphalt chips, it is necessary to carry out preparatory work, in particular, leveling holes, cutting down bushes, if any, removing grass and foreign objects. The leveled soil layer can be shed bitumen mastic, this will help increase the adhesion of asphalt chips to the road surface, but you can do without it.

Asphalt crumbs are laid evenly, and it is better to lay them in two layers of 8-10 cm each. After laying the first layer of asphalt chips, it must be compacted, and only then proceed to laying the next one. Moreover, if you use asphalt chips to arrange a sidewalk, then you can use a vibrating plate for compaction, and if you use a roadway or platform, a roller. Once the compaction is completed, the work can be considered complete.

Thus, laying asphalt chips can be done on your own; it is interesting that over time, the asphalt crumb coating only gets better, as more and more cars roll it over. Of course, asphalt crumbs still retain a relatively loose structure, so they are inferior in their operational characteristics asphalt, however, it is noticeably superior to the coating of crushed stone and sand.

The VICCO company will supply you with asphalt crumbs in the required volume and in the shortest possible time. We work with both corporate and private developers, and are also ready to advise you on all construction issues. Contact us!

Crumb asphalt consists of crushed materials. Often the material is used in various areas related to road construction. It has become most widespread in modern times, thanks to the advancement of technology, namely after the introduction of a special unit that is capable of removing layers of long-term coating without damaging the base of the “cushion”. In this article we will describe in detail how to lay asphalt chips with your own hands.

Asphalt crumbs contain bitumen and recycled construction crushed stone. Depending on the classification, the fraction does not exceed a few cm. Multi-raw material crumbs, formed from the composition of crushed stone, sand, bitumen, and concrete, are also found. Experience shows that multi-raw material crumb behaves most optimally under our conditions.

The crumb goes through a certain preparatory cycle before it turns into the finished product. The cycle consists of several stages at once:

• removal of old coating;
• removal to the factory;
• splitting up;
• sorting and dispatch.

Where is this material used?

The use of asphalt crumbs can be found in many areas. To a greater extent it occurs when:

• Construction of roads, highways;
• Construction of small sites near country houses;
• When sprinkling stadiums and play areas in parks and outdoor entertainment centers.

As you can see, it can be used in many areas; it is not uncommon to find crumbs in forested areas of parks, where bicycles and pedestrian paths. When constructing new highways, asphalt chips are used to strengthen exits and shoulders, protecting the new road surface from deformation and vibrations. Interesting feature recent years- this is what many construction companies use crumbs to sprinkle the top layer of the base before laying the finished floor. This serves as additional insulation from the damp foundation.

Today, crumbs have become popular among summer residents because of their relatively low cost. Modern village roads are built from crumbs. Indeed, in comparison with similar crushed stone or concrete roads, it has significant differences:

• It is highly resistant to moisture and various weather conditions;
• Durable;
• Not washed away by floods;
• Significantly lower in cost, given the low production costs.

Technology for laying asphalt chips

This technology began to be used in road construction relatively recently, but in a short time it has fully confirmed its advantage. As mentioned above, asphalt chips are a secondary product, more precisely a consequence of multi-layer removal of the old road surface followed by crushing. Despite the low cost of production, the material is distinguished by its significant strength and can be processed.

One of the main advantages of this material is considered by many to be the ability to densely fill all voids and cracks in the coating. Even with time and gradual compaction with the help of cars, such a coating only becomes stronger and more durable. Due to the dense laying, the road is practically not subject to erosion.

Working with such material is incredibly simple; the main thing is to know the basic cycle and laying technology, which includes several successive stages:

1. The first thing to do is to clear the masonry area as efficiently as possible, and then lay the so-called “cushion”. In each specific case, it may differ depending on the specification of the future road. For example, you can use crushed stone, concrete or broken brick. In some cases, it is justified to lay several layers of the listed materials.
2. After this, the surface must be carefully leveled using special road equipment.
3. Next, pour out the material of the future coating and level it over the entire plane.
4. The last stage includes compaction with rollers. After all the above stages, the road is ready for use.

Note: here it is necessary to note the peculiarity that for such coatings it is not recommended to use rollers weighing more than 10 tons. And if you pre-fill the canvas with bitumen, you can achieve better strength and impermeability of the coating.

Considering the main advantage of such a material, such as low cost, more and more people are filling the roads in their areas with crumbs. In addition, it is gradually replacing classical materials such as paving slabs and paving stones used for arranging playgrounds and park areas.

At self-installation manually it is necessary to similarly preserve the technology and stage-by-stage work in order to achieve a positive result.

Note: Special attention pay attention to the route of communications. Take into account the fact that sooner or later you will have to change pipes and the like, which will accordingly lead to the destruction of the canvas.

When we have determined the size of the plot, we order about 10-12 tons of asphalt chips per 100 square meters. Consider the amount of work. If the area is really large, it is better to rent a small skating rink. As a rule, the factory selling the material will be happy to lend its equipment for use, of course for an additional fee.

When the material is ordered, you can begin preparing the site, namely removing the top layer of soil. Keep in mind that you will have to remove at least 20 cm. As a result, a characteristic trench will form. If desired, you can put a layer of geotextile on the bottom, it will prevent soil subsidence.

A mound (cushion) of crushed stone and sand is laid on top of the geotextile or earth. Each layer is at least 3-5 cm. In principle, if the site is not planned high pressure, you can do without these materials.

Note: the volume of soil is large, so take care of removing the soil in advance.

After all preparatory work You can safely start pouring out the crumbs; you need to do this sequentially. For convenience, you should get a couple of assistants, because it will be difficult to cope with such a volume of work alone. The crumbs are poured out in small “batches” to avoid the formation of voids. If the area is large, it is better to use a roller. There is nothing complicated in managing it, but at the same time you will save a lot of time and effort. To achieve coating strength, bitumen emulsion should be applied first. Thanks to bitumen, it will only be stronger and will also become resistant to temperature changes during the cold period.

The technology for laying on roadsides and ramps is identical and is carried out according to the same scheme. The material is considered the best alternative to crushed stone and sand, but in comparison with the classic coating it does not have enough strength; after all, the crumb is loose in structure.

Important points

Working with asphalt crumbs is easy, but you need to know certain points. Asphalt crumbs must be placed in several layers - this mandatory requirement for major roads. The first layer of at least 7 cm should sink well after compaction. After which only the second “cake” is poured, also at least 7 cm. If the material is placed in parks or in local areas, such as entrances to a house or garage, then it is permissible to use one layer, but not less than 10 cm.
