Asphalting of small areas. Methods and stages of work execution

The most common and practical waylandscaping - this is asphalting, thanks to which buildings, structures, as well as adjacent paths and areas acquire a well-groomed, completed look. Therefore, the asphalting of small areas is no less important than laying asphalt on large-sized objects. It has its own specifics of work, for which a special maneuvering (on caterpillar or wheeled chassis) road construction equipment is used.

Factors to be considered for asphalting

Before conducting asphalting of territories in small areas, it is necessary to take into account such basic factors:

• relief and configuration of the site;
• presence of buildings and fences.

On this depends on the time of the installation, and whatwill be on the asphalting price. Small areas require many different materials, the use of special equipment, as well as work related to circumvention of technical structures and plantings.

Materials used in asphalting

Asphalting of small areas is performed withusing a cast asphalt-concrete mixture. This road-building material has a high density, roughness of the coating, which does not require compaction after laying, which is possible at low temperatures. Work is carried out with a special mixture heated to 180 - 200 ° C. Asphalting of territories up to 5m² perform using cool asphalt.

Technology of asphalt paving

Asphalting of small areas by technologydiffers from the construction of intensive highways. The main difference is the way of laying the substrate for asphalt mixtures, because the load on such a coating is small in the future. Accordingly, asphalting of sites, garages, yards is conducted with less stringent requirements.

The basis for laying consists of a layer of rubble,sand or hard concrete. Given that the load on the surface will be negligible, you can lay only one layer of asphalt. Its optimal thickness for the sidewalks will be 3-4 cm, for the driveway to the house - 5-7 cm. Asphalt laying works end with compaction of its base. This is done by means of ramming, rolling, or vibration, using a plate compactor or a two-shaft hand roller.

When carrying out the work, the roller must be smooth andevenly move throughout the stacked area. To the asphalt mixture is not lapped to the device, it is moistened with water. To reduce the depth of the transverse joints and to seal them, additional layers of liquid bitumen or asphalt-concrete mixture must be applied. Asphalt laying is carried out using technology with the use of special equipment to ensure that the coating was of high quality, not subjected to cracks, failures, had a long service life.

Methods of laying the coating

When laying asphalt pavement on small areas, one of these methods is used:

• without the use of special equipment;
• mixed.

The first method is suitable for asphaltinginaccessible areas for asphalt equipment. Laying and leveling is carried out manually with special construction tools, the compaction is carried out by a plate compactor or road roller.

With a mixed method, most of the work is carried out with asphalt laying equipment. Difficult and difficult areas are asphalted using hand tools.

Stages of work execution

Access roads, sidewalks, platforms nearbuildings should be smooth, durable and beautiful. Asphalting of areas for children can be carried out with colored materials. It is necessary to correctly asphalt them, having executed such works:

1. Carry out soil preparation. To do this, remove the top layer, and trowel the trench with a roller. Further, a geosynthetic web is laid, which prevents the absorption of rubble by the soil.
2. Lay the foundation. It can consist of sand, gravel, gravel or concrete.
3. Carry out asphalt laying and leveling. Laying the first layer of coating (cold or hot), the thickness of which is 5-8 cm and is spread by shovels throughout the territory. More durable is cold asphalting, (its price is much higher than hot styling).
4. Seal with the help of mechanisms such as a plate compactor or a manual double-roller.

Asphalting of small areas can be accomplishedas with the involvement of specialists, and independently. The main thing is to observe the technology for laying the coating, so that with further use it will withstand all kinds of loads and have a long service life. The prices for such services depend on the complexity and the area of ​​work performed, the number of consumables, and the type of equipment to be used.
