Place asphalt chips. Laying asphalt chips

Asphalt crumbs are a relatively inexpensive raw material that is obtained by crushing old, unusable asphalt pavement. This material, although its characteristics are inferior to full-fledged asphalt, is suitable for laying on roads and other objects with light loads. Most often used for the construction of temporary roads, sports grounds, adjacent areas and other objects that will not be subject to heavy loads.

Production of asphalt crumbs

It is a recycled product. There are two types of crumbs. The first type of this material is produced using a special cutter, which cuts off the old asphalt layer layer by layer. Old asphalt immediately after cutting it is crushed into small particles. Such crumbs have a finer fraction. This makes it better quality. Most often, asphalt chips, which are obtained using a milling cutter, are used immediately after their manufacture. If necessary, if it is necessary to increase the characteristics, bitumen or other additives are additionally added to it.

The second type is produced by crushing. Crushing is carried out using special crushing plants. Pieces of dismantled old asphalt are loaded into these installations. The output is asphalt chips of a larger fraction. Such crumbs are of lower quality. But it costs much less than the one obtained by milling.

Construction of roads from asphalt crumbs

Any road, no matter what kind of surface it has, needs to be followed certain rules. The construction of a road from asphalt chips can be divided into the following stages:

• Preparatory work include removing the top layer of soil along with all vegetation. This is done because in the future such vegetation will rot and the road may begin to sag. To prevent such subsidence, in places where road construction is planned, they remove upper layer soil. This is done using excavators.
• Arrangement drainage system - This is the construction of ditches or ditches along roads. This is done to ensure that water is drained from the road surface into the ditch as quickly as possible. The presence of a high-quality drainage system allows you to increase the service life of the road several times. The arrangement is carried out using mini excavators and.
• Geotextiles laid as the lowest layer. However, very often, to save money, this layer is neglected. But as practice has shown, geotextiles can significantly increase the service life of the road.
• Sand bedding is a uniformly distributed layer of sand. Sand is transported to road construction sites by dump trucks and leveled by excavators of various capacities. The sand layer should be at least 10 centimeters. After leveling it, the sand layer must be compacted. This must be done using . But due to the fact that mainly country or temporary roads are built from asphalt crumbs, compaction of the sand layer is very often neglected.
• Crushed stone layer– another layer of bedding, which consists of crushed stone. Ideally there should be two layers of crushed stone. The lower layer consists of coarse crushed stone, the upper layer consists of fine crushed stone. But under the road made of asphalt crumbs, only one layer of crushed stone of any fraction that is more accessible is almost always poured.
• Laying asphalt chips carried out manually. It is transported by dump trucks and leveled using excavators, backhoe loaders, etc. At this stage, they play an important role handmade. After all, the final leveling of this asphalt surface is carried out using an ordinary shovel.
  Asphalt crumbs, like regular asphalt, require compaction. But more often than not, it thickens this material under the pressure of cars passing over it.

Advantages of roads made of asphalt chips:

• 1. Cheapness. Due to the fact that it is a very cheap material, it can be afforded a large number of population. Very often, summer residents chip in on asphalt chips and build roads on their own. In addition, it can be laid on already filled crushed stone.
  2. Little demand. If you compare the level of demand with the amount of crumbs produced, you can almost always buy it in the warm season. This is due to the fact that a very large amount of old asphalt is removed and recycled. Recycled, it is used only for paving temporary roads, sidewalks and places that are not subject to heavy loads.
  3. High strength. Roads that are built from asphalt chips have the same strength as regular asphalt roads. The truth is that it has a much shorter service life.

Which is better, asphalt or asphalt crumbs?

If you think logically, then asphalt is new material, which is intended for road surfaces. Asphalt crumbs are a kind of waste from asphalt pavement. Everyone knows that waste cannot be of higher quality than the original raw materials. But in any case, it is worth noting that it has excellent properties that can turn a crushed stone road into a full-fledged asphalt road. And this is at a very reasonable cost. If cash do not allow you to build a road from full-fledged asphalt, then it will be an ideal material.

Material production technology for starting work

As has been said more than once, asphalt crumbs are produced by removing the top layer of the road surface. Road repairs are carried out in Moscow every year from April to October. To remove the coating, a special complex road mill is used, which crushes the surface, turning it into small particles. The fraction of the resulting material is 0-40 mm. While the cutter is operating, the produced crumbs are continuously loaded into dump trucks and transported to the construction site. The price of this material is much lower than even that of crushed stone, and the wear resistance is excellent.

To quickly calculate what is needed for your construction work amount of material, use a convenient asphalt crumb volume calculator. You can correctly determine the required volume of material if you have information about the length and width of your area where backfilling will be done.

Construction and filling of roads from asphalt crumbs

Next we will consider next stage, the most important thing is to do it right. After delivery to the work site, the laying of asphalt chips begins using the following technology. The dump truck dumps it in one or several piles, after which the excavator (and for small volumes up to 100 m3, working shovels) begins to evenly level the surface of the canvas. The layer of filling the road with asphalt chips is usually no more than 20 cm. The video above shows the whole process.

And finally road surface rolled with a roller to achieve greater density. We would like to note that for country roads it is not necessary to use a roller; compaction with the wheels of passing cars is sufficient. However, to create a high-quality canvas, we recommend not saving these small funds, but still tamping with a road roller. This will increase the service life of the coating, if only because it will reduce the formation of rutting in areas of greatest load.

To obtain maximum strength, the finished road surface is treated on top with a special bitumen emulsion; it binds the upper particles together, forming a film. This service is optional and is usually performed at the request of the client.

Asphalt crumbs began to be used in road construction relatively recently. This material has become especially popular in Lately, with the advent of the latest specialized equipment.

Asphalt crumb is a secondary raw material obtained by layer-by-layer cutting of old asphalt pavement and crushing it. Despite the fact that this material is relatively cheap, it is durable and easy to process.

In order to make sure that the material is available, you can follow the link http://vestteh.ru/catalog/asfaltovaya-kroshka.html, and how to lay this material is described in detail in this article.

Technology for laying asphalt chips

The most important advantage of this road-building material over others is that it is laid as tightly as possible, filling all the voids. Being compacted during operation by the wheels of vehicles, asphalt crumbs form sufficient durable coating, which is resistant to erosion.

Working with asphalt crumbs is extremely simple:

1. To begin with, it is necessary to clear the masonry surface, after which, lay a layer of brick, concrete and recycled crushed stone.
2. Next, the surface is carefully leveled using specialized equipment.
3. Asphalt crumbs are placed on special technology, leveling evenly around the entire perimeter.
4. Next, the surface lined with asphalt chips is compacted with special rollers. It is worth considering that their mass does not exceed fourteen tons.

After compaction with rollers, the asphalt crumb road can be used for its intended purpose.

Important nuances

Despite the ease of installation, working with asphalt crumbs has several features:

1. When arranging roads, asphalt crumbs are laid in two layers, and the thickness of each of them is 8-10 cm. The second layer is laid only after the first has been thoroughly compacted.
2. When strengthening roadsides, asphalt chips are placed and compacted in the same way.
3. If there are holes on the road, asphalt chips are used for filling, which saves money and ensures the safety of vehicle movement.

You can see how asphalt chips are laid in this video:

Simple and affordable way DIY arrangement of areas and paths near the house - laying asphalt chips obtained by recycling old asphalt pavement after its layer-by-layer cutting and crushing. This recycled material, unlike paving slabs, does not require preliminary calculations and complex installation activities, provides high density and uniformity of coverage due to the bitumen contained in the mixture. Often used for patching ordinary roads.

To cover 100 m2 you will need approximately 10 tons of material and a roller - manual or conventional. This consumption rate is sufficient to improve the area near the house. The created layer is 40 mm. Its service life is 7-10 years.

Work order

• Marking the site, removing 15-25 cm of soil while maintaining a slight slope for drainage of melt and rainwater.
• It is recommended to cover the bottom with geotextiles.
• Installation of borders and posts.
• Laying a layer of sand with a tamper, and then crushed stone, also with a tamper. For the home site, a 15 mm thick crushed stone layer is sufficient. The grain size of the material is 20-40 mm. In areas with high groundwater, larger fractions are used - 70-140 mm. They act as drainage.

How to lay asphalt chips?

In areas of up to 100 m2, work can be carried out independently; for larger areas, it is recommended to find helpers.

The technology is quite simple:

• the material is scattered around the perimeter and leveled;
• roll with a hand or large roller;
• To give additional strength and durability, the coating is filled with bitumen emulsion.

Self-laying asphalt chips near the house

The simplest and accessible method arrangement beautiful paths and the parking lot near the house is asphalted. It uses asphalt chips. Its installation does not require precisely calibrated calculations and lengthy installation, unlike concrete slabs and paving slabs. Even if you are new to construction, laying asphalt near your house will not be difficult. Let's consider the algorithm of actions preceding this operation, as well as the asphalt paving procedure itself.

Work begins with digging a pit. Its depth should take into account all elements: sand cushion, crushed stone and asphalt itself. The end result should be in line with the rest of the area. It is advisable to compact the bottom of the path base with a vibrating plate.

Spread in an even layer on the bottom required amount crushed stone and level it. For a home plot, a layer of 15 cm with a fraction with a diameter of 2-4 cm is sufficient. Larger fractions of 7-20 cm are required if groundwater come close to the surface. In this case, the crushed stone will serve as drainage. Do not forget to compact the crushed stone with special vibrating machines and rollers up to 6 times. It is at this stage that slopes are created (0.5 cm per meter of track) where the water will flow rainwater. Also at this stage they are laid decorative elements: fences, posts, curbs, hatches.

The final step is laying the asphalt. They place it at the rate of 1 ton per 10 square meters. This is enough for pedestrian paths and parking lots near the house with a thickness of 4 cm. Special machines and vibrating plates are used for compaction. If you plan to lay several layers, then bitumen is applied between them for adhesion. Periodically, the laid asphalt is watered with water for better compaction. Correctly completed stages of work will ensure impeccable service of the asphalt pavement for 7-10 years.

Laying asphalt chips

Once removed, worn-out road surfaces turn into recyclable materials. The crushed material is used in the production of asphalt, construction and landscape design. Its use reduces the load on Natural resources.

Composition of asphalt crumbs

The main components of the material are gravel, crushed stone, sand and bitumen. Concrete may also be present as a binder. The ratio of components depends on the brand of asphalt, the type and condition of the road surface during removal. On average, a crumb includes:

The concentration of the latter in crumbs is less than in asphalt - the binding component leaves the coating during the operation of the road, creating the need for its repair.

Specifications

The product is a crushed road surface. It is carried out at the repair site - asphalt paving equipment includes equipment that crushes the road surface. Grinding is carried out after removal. Pieces of asphalt are sent to granulate into crushers.

The result is crumbs 3–5 mm in size, differing, depending on the production method, in the following parameters:

Tiny may include different types asphalt - this affects the weight and other characteristics of the product. So, the mass is 1 cubic. m of crushed pavement varies between 1.5–2.0 tons. The heaviest is asphalt concrete; mixtures without cement have less weight due to the absence of fine fractions.

Disposal Alternatives

Initially, crushed asphalt paths were used as temporary routes in landfills. Otherwise, the material acted as waste that did not decompose in the environment. Without a solution to granulate the asphalt mixture and add it to new products, the debris left behind from road repairs would clutter landfills while increasing pressure on natural resources. Recycled bedding replaces primary components.

What is asphalt crumb good for?

Material used industrial enterprises and private individuals. Recyclable materials are included in new asphalt mixtures. Depending on the type of product (cold or hot), the waste coefficient in the new material is 0.25–0.6. That is, the share of crumbs reaches 25–60%.

The material is also used for the following works:

• local repairs - the crumb will reduce the consumption of primary asphalt when filling holes;
• preparing the base of the route;
• covering secondary and country roads with low level loads;
• strengthening artificial relief - recyclable materials can be used to fill the shafts of railway and highway tracks;
• improvement of domestic and public areas - laying of asphalt crumbs is carried out in parking lots, country roads, sports grounds and floors technical premises.

To work with recyclable materials, you will need equipment capable of compacting and melting the bitumen into the mixture. The last procedure is not necessary - you can put the crumbs without heat treatment - binder will bind particles together during compaction.

Technology for laying asphalt chips

The application process depends on the area of ​​application - when strengthening the relief, the mixture is scattered in an even layer (at least 20–30 mm) and leveled with a roller tool. In the case of laying paths, the site is first marked, and soil is excavated inside the contour of the future roadbed. Crumbs are poured into the recess and then compacted. The principle remains the same when creating secondary highways and landscaping the yard.

How to lay asphalt chips with your own hands

First of all, the required volume of raw materials is calculated.

Paths made of asphalt chips in the country will require a depth of 30–40 mm. With a width of 50 cm per 100 m of coverage, you will need 0.15 cubic meters. m of material. Or 0.23–0.3 tons of product, depending on density.

With a Kamaz carrying capacity of 6 tons, one vehicle is enough (almost 2 kilometers worth of raw materials) to mark routes in the yard and fill holes behind the gates.

1. Marking - a diagram of paths is drawn, which is transferred to the territory of the site.
2. Preparing the site - 30–40 mm recesses are dug in the marked contours - the basis of future paths; boards or a concrete window sill can be placed at the bottom of straight sections to strengthen the structure in loose soil. Instead, geotextile bedding can be used.
3. Filling the crumbs. If you plan to melt bitumen, you will need a tin barrel and thick gloves. A rake can be used for leveling.
4. Tamping. For large jobs, such as priming the road in front of a private house, a miniature skating rink is rented. Decorative and narrow paths inside the yard are compacted manually with a roller tool. Wait at least 24 hours for the material to cool or set before using a new route.

Laying asphalt chips with your own hands is easy. The presented algorithm is also suitable for improving technical premises: a barn or a garage. When creating the basis of a parking space, the weight of the vehicle is taken into account. A parquet SUV will require a thicker floor compared to a passenger model.

Alternative options

Road recyclables can be replaced with sand, crushed stone or mixtures of materials obtained from nature. Expanded clay is also used - a voluminous porous product of clay processing when high temperatures. These structures lose out to waste road repairs by cost, durability or need to use natural resources.

Pros and cons of using asphalt crumbs

Reducing the burden on the environment and utilities is one of the main advantages of the material. Lining with recycled materials leads to less use of gravel and bitumen - products of the mining and oil refining industries. The advantages of the decision to lay asphalt chips also include:

• pavement strength - a mixture from the highway will ensure the strength of your home driveway;
• weather resistance;
• aesthetic appearance - combines external characteristics gravel and asphalt surfaces.

Disadvantages of the product are considered to be color changes caused by weathering on the coating and inconsistent quality. The crumb composition can include different types of asphalt: from the classic mixture to concrete and sand variations. This makes it difficult to determine the final characteristics of the product. Residual traces of spills of oil, acid or other aggressive substances that occurred during the operation of the track can affect the health of users of the track made from recycled materials.

One of the most common recycled 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 crushing old asphalt pavement, removed during replacement or repair of the roadway, using cold milling. 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 of asphalt chips costs. 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 chips 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 on open fire V 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, along 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 less harmful effects due to the absence of bitumen in the composition. 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 convenience in styling and prefer to spend extra money on yourself and your loved ones, rather than on Construction Materials. For parking or driveway, sports ground or garage floor - this material will satisfy any of your needs!
