Active snow melting and deicing pavement structure and paving process thereof

Abstract

The invention discloses an active snow melting and deicing pavement structure comprising a roadbed, a plastic base layer is laid on the roadbed, a steel plate layer is laid on the plastic base layer,and an asphalt mixture surface layer is laid on the steel plate layer; a heating cable and heat-conducting metal are arranged between the plastic base layer and the steel plate layer, one end of the heat-conducting metal is located between the plastic base layer and the steel plate layer, and the other end extends into the roadbed; a temperature sensor is buried in the bituminous mixture surface layer and used for collecting the temperature of the bituminous mixture surface layer and sending the collected temperature to a controller, and the controller is used for comparing the temperature ofthe bituminous mixture surface layer with a preset freezing point temperature threshold value and controlling whether the heating cable is put into work or not according to the comparison result. Snowand ice on the road surface can be rapidly removed, road smoothness and driving safety are guaranteed in time, a large number of manpower and material resources are saved, the road performance and durability are good, the structure is reasonable, and durability is achieved.

Description

technical field [0001] The invention belongs to the technical field of road engineering pavement pavement, and in particular relates to an active snow-melting and deicing pavement structure and a paving process thereof. Background technique [0002] In the early spring and winter, the roads in northern my country have very common snow and ice phenomenon, and the roads in most southern regions also frequently experience ice condensation. Document 1 (Shen Chaoping, Lv Jianliang, Ma Guoqing, etc. Preliminary study on maintenance technology [J]. Highway Traffic Science and Technology, 2008, 25 (4): 239-242.) The research shows that the adhesion coefficient of the road surface is reduced by 60%-75% due to the existence of snow icing and icing, which leads to vehicle damage. The stability of braking and steering operation is significantly worse. In this case, road vehicles will often have brake failure, direction loss of control, skidding, deviation, etc., which are unfavorable to n...

Problems solved by technology

However, the current active snow-melting and ice-melting methods still have some shortcomings, mainly as follows: in the self-stress elastic pavement snow-melting and ice-melting technology, the road compaction is insufficient, and there are durability problems; With the extension of time, the ice capacity has a certain attenuation in its performance; the energy conversion snow melting and ice melting technology is difficult to maintain and repair
