The construction of roads is the most important industry in general. After all, only thanks to good roads can passengers enjoy travel.
It turns out that roads have a different type of road clothing. Road clothing are different combinations of building materials with which the road is made. On which material it will be made on and its strength, durability and even load will depend.
Clothing for the road can be from the simplest to complex. Let’s start with the simplest. Additional materials do not need such clothing, it is built from what is. For such roads, all irregularities are cut off, hollows are covered and a ditch is made on the sides to drain water. And that’s it, but there are shortcomings in such a road. This road is not intended for intensive movement. Slightly best gravel roads. Such roads can serve for a long time, but they need to be close in time in cases of irregularities.
Modern asphalt roads are made from many layers and different combinations of road construction materials. The thickness of the road clothing here depends on the alleged load on the road and the properties of the soil. But, the asphalt coating should not be completely smooth. Here we need a small roughness -this is for better grip of the wheels with road coverage.
Road surface can also be laid from several layers of different crushed stone. Such roads are called macadam. such a road requires a strong base, all crushed stone is rolled up by rollers. And for better strength, the surface of such a road is also impregnated with bitumen.
