Anti-freezing asphalt pavement structure and construction method thereof
The invention discloses an anti-freezing asphalt pavement structure, and belongs to the field of design and construction. The structure includes low-temperature phase-change cement paste prepared by the method can absorb heat at a high temperature and release heat at a low temperature, so that the phenomenon of insufficient skid resistance of a pavement caused by icing of an asphalt pavement is effectively inhibited. A technical scheme is as follows: the asphalt pavement structure comprises a pavement base layer, a thin paste sealing layer, a pavement lower surface layer, a pavement middle surface layer and a pavement upper surface layer from bottom to top; wherein the pavement base layer is a cement stabilized macadam base layer, the slurry seal layer is a mixture of emulsified asphalt and aggregate, wherein the pavement lower surface layer is common asphalt concrete, and the pavement middle surface layer and the pavement upper surface layer are made of asphalt concrete mixed with low-temperature phase-change cement paste. According to the anti-freezing asphalt pavement structure provided by the invention, the waterproof performance of the asphalt concrete is improved; the anti-icing asphalt pavement structure can effectively prevent the pavement from icing.
