Problems solved by technology

However, this invention also cannot solve the situation that concrete is penetrated by rain and snow, resulting in electric leakage; and it is equally heated for all snow accumulations, and different heating methods cannot be used for different degrees of snow accumulations

Abstract

The invention discloses a method for constructing road surfaces.The method includes steps of (1), carrying out paying off and leveling; (2), arranging basement layers and leveling the basement layers; (3), arranging heat-insulation layers on the basement layers; (4), laying electric heating materials on the heat-insulation layers; (5), paving concrete bottom layers on the heat-insulation layers; (6), spraying epoxy asphalt waterproof bonding layers on the concrete bottom layers; (7), paving concrete top layers on the waterproof bonding layers.The electric heating materials are numbered when laid and are divided into first arrays and second arrays; the heights of the electric heating materials of the second arrays are lower than those of the electric heating materials of the first arrays when the electric heating materials are laid.

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 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 does not hav...
