Laying asphalt chips with your own hands: technology

A simple and affordable way to arrange playgrounds and paths near your house with your own hands is to lay asphalt chips obtained by recycling old asphalt pavement after its layer-by-layer cutting and crushing. This secondary material, unlike paving slabs, does not require preliminary calculations and complex installation measures, and provides high density and uniformity of the coating due to the bitumen contained in the mixture. Often used for pothole repair of ordinary roads.

Preparation for laying asphalt chips

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.

Asphalting

After creating a crushed stone base, you can begin laying. For this purpose, material of different grain sizes is used. It is difficult to prepare a high-quality resinous mixture at home, so it is better to purchase it. The advantages of using a factory mixture include:

• saving time in production;
• use of quality material.

To lay asphalt in your yard, you need to use a fine-grain material. It is laid in one layer 5–7 cm thick.

When creating an access road, the material is laid in several layers. Fine asphalt is placed below, and coarse asphalt is placed on top. The coating is compacted with a roller and filled with bitumen to better connect the layers.

Self-laying asphalt chips near the house

The simplest and most affordable method of arranging beautiful paths and parking near the house is asphalting. 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.

Pour the required amount of crushed stone onto the bottom in an even layer 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 will be required if groundwater comes 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 rainwater will flow. Also at this stage decorative elements are laid: fences, posts, curbs, hatches.

The final step is laying the asphalt. They lay 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.

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:

• crushed stone - 25–45%;

• natural and artificial sand - 50–60%;
• bitumen - 3–7%.

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:

• The concentration of the bitumen component is that there are more binding substances in the crumbs, which are produced on site, than in the removed waste sent for recycling.

• Requirements for operating conditions - material from the road is recommended to be used in summer; it must be heated to activate the bitumen and is suitable for completely replacing the sheet. The product obtained from raw materials delivered to the production site is suitable for cold seasons. Due to the lack of binding components, it is recommended to use it to eliminate local defects.
• Price. A cubic meter of material from a cutter, on average, costs 800–1000 rubles. For a similar volume of crumbs from a crusher they charge 600–800 rubles. The cost depends on the buyer's area of ​​residence, as it includes delivery costs.

The crumbs may include different types of 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.

What else is important to pay attention to

Now that you know how to install cut asphalt, we will provide some recommendations to help you select the material and install it.

What is important to pay attention to:

• Cut color The quality of the material directly depends on its color: the darker the cut, the better it is. This means that the asphalt has not been in use for long, and this mixture also contains more bitumen. And the more bitumen, the better the particles will subsequently adhere to each other. The lighter the cut, the higher the likelihood that when it was received, crushed stone and sand from the road cushion also entered the crusher.
• Compacting cuttings with a car We have already said above that if you don’t have a vibrating plate at hand, you can compact the coating with a car: the heavier the vehicle, the better. Just keep in mind that you need to drive on the rolled material extremely carefully. Under no circumstances should you skid on material that has not yet been compacted!
• Using a gas burner If you are laying the cuttings in cold weather, it is best to warm them up additionally. This will improve particle adhesion. To do this, before compacting the material, use a regular gas burner. This way you will melt the bitumen and improve the quality of your future coating.

What is asphalt crumb good for?

The material is used by industrial enterprises and 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 traffic levels;
• strengthening artificial terrain - recyclable materials can be used to fill the shafts of railway and highway tracks;
• improvement of household and public areas - laying of asphalt crumbs is carried out in parking lots, country roads, sports fields and floors of 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 lay the crumbs without heat treatment - the binder will bind the particles together during the compaction process.

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.

conclusions

Asphalt crumbs (asphalt granulate) are one of the most popular materials for the construction of hard road surfaces and pedestrian areas. Of course, granulated asphalt is less durable than asphalt itself, but its cost is much lower. In those places where there is no need to use fresh asphalt concrete, asphalt crumbs are the best option. Having high performance characteristics, this material is superior to other coating options in its class. In other words, granulated asphalt, in comparison with analogues, is the highest quality and durable material for the construction of village or temporary roads, as well as parking lots, sidewalks, adjacent areas and other small areas. The only exceptions are roads that involve heavy traffic. Asphalt crumbs are made from asphalt that has been crushed. The composition of asphalt crumbs depends on what the asphalt concrete from which it was made consisted of. If the asphalt granulate was produced from a high-quality asphalt coating, then the performance characteristics of the crumb itself will be high. At the same time, fresh asphalt granulate, which is milled immediately after removing the asphalt layer and immediately delivered to the customer, will have the best quality. If asphalt crumbs have been stored in a warehouse for some time, their characteristics and cost are reduced.

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 from 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 the external characteristics of gravel and asphalt pavement.

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.

Reviews

Users rate the material positively. Reviews show that recyclable materials are suitable for designing passenger transport routes. Quotes taken from reputable construction forums.

Leonid: “Trucks left ruts on the crumb road, especially in the summer. The material is perfect for passenger cars - we filled it up 5 years ago until we observed any chipping or pushing through.”

Oksana: “We used it to design paths between the beds. There are no complaints - it doesn’t slip, doesn’t retain rainwater, doesn’t crack in the cold and looks neat.”

Mikhail: “We thought about buying crushed stone, but crushed asphalt was almost 2 times cheaper - the highway was being repaired next to the site. It falls asleep and compacts easily; after 2 years there are no complaints.”

Asphalt crumbs are useful recyclable materials. The material is used in various industries and is suitable for landscape design. With its help, durable courtyard paths and public routes with low traffic flow are created.

How to lay asphalt chips

Asphalt crumbs began to be used in road construction relatively recently. This material has become especially popular recently, 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 https://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. When compacted by vehicle wheels during operation, asphalt chips form a fairly durable coating that 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 chips are laid using a special technology, leveling evenly along 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.
