Abstract

The invention relates to a pavement construction method which comprises the following steps: (1) paying off and leveling; (2) arranging a base layer and flattening the base layer; (3) arranging a heat insulating layer on the base layer; (4) laying electrical heating material on the heat insulating layer; (5) paving a concrete bottom layer on the heat insulating layer; (6) spraying an epoxy asphalt waterproof adhesive layer on the concrete bottom layer; and (7) paving a concrete top layer on the waterproof adhesive layer.

Description

technical field [0001] The invention relates to a pavement construction method, in particular to a snow-melting concrete pavement construction method. Background technique [0002] Most areas in my country belong to ice and snow areas, and the problem of snow and ice on road surfaces (ie, asphalt concrete road surfaces) is relatively common. Especially in the early winter and early spring seasons, under the effect of temperature changes and vehicle loads on the snow on the road surface, thin ice is easily formed on the road surface, which affects road traffic safety. According to the analysis, ice and snow greatly reduce the adhesion coefficient and adhesion force of the road surface, and the braking stability and steering operation stability of the vehicle will all become worse. The driver's vision is blurred, which leads to frequent traffic accidents, and the traffic accident rate in ice and snow days increases significantly. [0003] The current asphalt pavement itself ...
