Abstract

The invention relates to the technical field of municipal road construction, in particular to a municipal road asphalt concrete pavement construction method. The municipal road asphalt concrete pavement construction method comprises the following steps: L1, laying a road, laying a road base layer, an air heating pipe mounting layer, a waterproof layer and an asphalt concrete pavement layer from bottom to top in sequence, wherein the air heating pipe mounting layer comprises an upper heat radiating layer contacting the waterproof layer and a lower heat insulating layer contacting the road base layer, the upper surface of the lower heat insulating layer is provided with an upper notch, the lower surface of the upper heat radiating layer is provided with a lower notch, the upper notch and the lower notch are matched to mount an air heating pipe, and an air inlet and an air outlet of the air heating pipe are exposed out of the road. By adopting the municipal road asphalt concrete pavement construction method, an ice and snow condition of a pavement can be automatically detected, the ice and snow are molten by automatically heating the pavement by virtue of warm air, a electric leakage phenomenon is avoided, and safety and reliability are realized.

Description

technical field [0001] The invention relates to the technical field of municipal road construction, in particular to a municipal road asphalt 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 asphal...
