You can see different roads built in different technologies and the most known one is asphalt road, The road asphalting is usually done with granular sand, stone dust and asphalt mixture. The mixture is heated to a certain temperature, than melt liquid asphalt is transported in special vehicles to the road sector, and leveled with special mechanisms and equipments. The asphalt cover usually consists of 5-7 cm thick layers of mixture asphalt, with amount of equally taken gravel, sand, stone powder and melted asphalt.
High-quality asphalting must be made on a reliable basis, which is usually made of gravel basis and 2-6sm asphalt layers: The bottom layer is spread with large gravel, which contributes the strength and economizes while the upper layer is spread with smaller gravel, which provides surface water tightness and longevity.
The total thickness of the road hangar depends on the ground bear ability and supposed transport overloading.
