Construction method using water resistance layer and stone mastic asphalt

摘要

In the present invention, a waterproof layer is formed on an auxiliary layer, a base layer or a bridge surface of a general asphalt pavement layer, and a stone mastic asphalt is laid on the base layer or pavement. By adding a modified mixed material and a filler mixed material to the waterproof layer, It is possible to improve the waterproof function of tack coat or prime coat and to improve the bonding strength with the waterproof layer by forming a stone mastic asphalt using the same modifying admixture and filling admixture as the waterproof layer on the upper part of the waterproof layer, To a packaging structure for improving the durability of packaging by using interlocking. In addition, the upper part of the stone mastic asphalt is provided with a porous aggregate to improve the resistance to freezing and thawing.
