INVESTIGATION OF THE EFFECT OF SHALE MINERAL POWDER ON THE PHYSICAL AND MECHANICAL PROPERTIES OF ASPHALT CONCRETE

Abstract

In the articleWork has been done to obtain shale mineral powder on the basis of local raw materials and develop technologies to improve the physical and mechanical performance and durability of asphalt concrete, thereby increasing the physico-mechanical performance and durability of asphalt concrete, the density of fine-grained hot dense asphalt mix with shale mineral powder. the water absorption index of the asphalt concrete mixture decreases, the strength increases and the transport performance of the road improves.
