At first glance, laying asphalt is quite easy.

But it seems so only from the outside.

So, just to lay the asphalt should be in dry weather.

Before laying it must be cleaned of dirt and leveled the ground.

During the paving of hot air mixture must be heated above + 5 ° C in the spring or summer and above + 10 ° C? autumn. But that's not all the nuances.

Read on.

instructions

1

For 3-5 hours before laying the foundation processbitumen or bitumen emulsion. If the foundation is constructed with the processing of organic materials or binders of freshly laid asphalt layer bottom, it is not necessary to handle it with bitumen. To the asphalt had no seams need paver equipped with special equipment, heating edge previously laid asphalt strips. You can arrange the joint laying on the edge of the board.

2

Compacted asphalt from heat and hot mixin two stages: first, the pre-compacted asphalt, driving through it 5-6 times a light road roller at a speed of about 2 km / h. Then a final compacted heavy road roller passing through it 4-5 times at a speed of about 5 km / h.

3

If an asphalt coating before the rink is notformed waves and imprinted marks from the drum, then compacted asphalt successfully. After a couple of aisles easy roller should be checked with the help of a three-meter rack and cross slope flatness pattern. It is necessary to establish the right number of passes roller in one place using the test rollers. Compacted asphalt in places that are inaccessible to rollers, you should use the hot metal compactors.

4

It is necessary to seal the asphalt as long as the followingrammer from bumps on the surface of the coating will not disappear completely. Arranging asphalt covering, check the temperature of the mixture during the laying and compaction, as well as the thickness and evenness of asphalt laid. Do not forget also about the adequacy of sealing mixture as a coupling edge of asphalt strips, respecting the design parameters.

As you can see, the paved roadalone is difficult enough, but still, this task is feasible. This means that the satisfaction of work done, you get incredible. Thus, the road paving is part of a complex accomplishment territory. Therefore, the final result depends precisely on the quality of the laid web. Performance and durability of expensive quality also depends on the equipment used in the process of laying asphalt.
