A road body with functions of preventing cold and freezing

Abstract

The invention belongs to the field of roads and specifically relates to a road body with an anti-cold anti-freezing function. The road body comprises a damp-proof layer, a heat insulating layer, a heating cable layer, a pavement bed course and a pavement layer which are laid on a leveled and cleaned pavement base course successively from bottom to top, wherein the heat insulating layer is used for preventing downward transfer and loss of heat, and the pavement bed course is used for fixing and protecting the heating cable layer. The heating cable layer comprises multiple uniformly-distributed heating areas. There is a reinforcing fixing gap between two adjacent heating areas. A heating unit formed by cross arrangement of heating cables is at least arranged in each heating area. Each heating unit comprises four uniform heat areas formed by heating cable crossing. A temperature-sensing probe is arranged in at least one uniform heat area in each heating unit. According to the application, the icy pavement problem is thoroughly solved. By heating a pavement before the pavement is frozen, it is guaranteed that the pavement will not be frozen. Meanwhile, performance of the road body is raised, and the problem that performance of the road body is influenced and service life of the road body is shortened due to icing of the pavement is prevented.

Description

technical field [0001] The invention belongs to the field of roads, and in particular relates to a road body capable of preventing the road surface from freezing in cold weather and having functions of preventing cold and freezing. Background technique [0002] The existing commonly used road surface snow melting and deicing methods mainly include manual or mechanical removal method, snow melting agent method, etc. The effect of snow melting and deicing is not ideal, and snow can only be melted when there is ice and snow on the road surface, and it cannot be used when ice and snow accumulate on the road. Take precautions before pavement. The most commonly used deicing agent can also damage the performance of the existing pavement, and has problems such as slow snow melting speed, low intelligence, low efficiency, and high energy consumption. Contents of the invention [0003] The purpose of the present invention is to provide a high degree of intelligence to solve the abo...
