Novel anti-freezing pavement
The invention belongs to the field of roads, and particularly relates to a novel anti-freezing pavement. The pavement comprises a damp-proof layer, a heat insulation layer, a heating cable layer, a pavement cushion layer and a pavement layer. The damp-proof layer, the heat insulation layer, the heating cable layer, the pavement cushion layer and the pavement layer are sequentially laid on a leveled and cleaned pavement foundation layer from bottom to top. The heat insulation layer prevents heat from conducting and being lost downwards, and the pavement cushion layer and the pavement layer are used for fixing and protecting the heating cable layer. The heating cable layer comprises multiple evenly distributed heating areas, and each heating area is formed in the mode that at least one heating cable is distributed on the heat insulation layer. Reinforcing and fixing gaps are reserved between adjacent heating areas. A temperature sensing probe is arranged between the heating cables of each heating area. Heat uniforming gaps are reserved between the temperature sensing probes and the heating cables. A cooling layer used for evenly dispersing heat generated by the heating cable layer is further disposed between the heating cable layer and the heat insulation layer. The structure completely solves the pavement freezing problem, a pavement is heated before the pavement is frozen, and it is guaranteed that the pavement can not be frozen; meanwhile, the performance of a road body is improved, and the situation that road performance is affected and the service life of the road body is shortened due to pavement freezing is prevented.
