ROAD STRUCTURE

摘要

FIELD: construction.SUBSTANCE: road structure placed on an earth work having a rated longitudinal inclination and a transverse inclination from 10 ppm to 50 ppm (from 10? to 50?), includes a drainage layer, a base and a coating. At the same time in case of longitudinal inclinations of the earth work above 10? the transverse inclination of the soil base of the road surface is increased from more than 50? to 70?.EFFECT: provision of stable strength and durability of the road structure during periods of overwetting by reduction of a water filtration path in a drainage layer and the time of the soil base moistening.2 dwg
