Quite often lately the question arises when, finally, we will have good roads. Is it really so difficult at least once to build a normal solid road that would not be repaired every year. How nice it is, probably, to drive a car with a breeze, not being afraid to run into a huge hole, and then send the car for repair. Maybe you just need to follow all the rules when building roads. How are roads actually built? Of course, road construction is a rather laborious and complicated process. At first glance, it seems so simple. In order to build a road, you need to do the following work:
Instructions
Step 1
Carry out a survey of the soil on which the road will run, this is necessary in order to avoid sinkholes or subsidence of the soil after the road has already been laid. Next, carry out the development of the soil (a special deepening is made in the soil, the soil is compacted and compacted) using special machines, in rare cases this work is carried out manually.
Step 2
Lay a gasket from a new material - geotextile, this is necessary so that the crushed stone that will be brought by trucks does not fall into the ground, since it will not withstand the weight of a loaded vehicle. Then lay the dump slag and lay a granite shield on it, this is necessary to connect all layers with the base of the road.
Step 3
Lay a layer of crushed stone, but not just in bulk, but using a special technology, first coarser crushed stone, then finer crushed stone, which rolls and seeps into the cracks between large rubble, while clogging up the voids. After that, the foundation of the future road becomes more dense, stable and resilient.
Step 4
Lay asphalt on top of all these layers, which also lay in several layers, depending on the type of road and the load on the roadbed. Naturally, each road has its own type of asphalt, it can be coarse-grained, dense, porous, fine-grained.
Step 5
Tamp the asphalt with the help of special machines, under pressure the asphalt adheres more firmly to all the previous layers of our road. An important role in the construction of roads is played by its foundation, or, in other words, the foundation. If the foundation is solid, reliable and durable, then the road itself will serve us for more than one year. However, it is worth applying and introducing new developments and technologies into road construction, and then, perhaps, we will achieve a solution to road problems.
