Anti-freezing drainage asphalt road
An anti-freezing drainage asphalt road comprises a roadbed layer, a dense-graded asphalt mixture impervious layer and an anti-freezing drainage asphalt mixture surface layer, the dense-graded asphalt mixture impervious layer is laid on the roadbed layer, the anti-freezing drainage asphalt mixture surface layer is laid on the dense-graded asphalt mixture impervious layer, and the dense-graded asphalt mixture impervious layer is laid on the anti-freezing drainage asphalt mixture surface layer. A plurality of gaps are formed in the anti-freezing drainage asphalt mixture surface layer and are communicated with one another, and the void ratio of the anti-freezing drainage asphalt mixture surface layer is 15%-30%; compared with the prior art, the invention has the beneficial effects that the anti-freezing performance of the pavement can be effectively improved, the pavement structure is protected in a low-temperature environment, and the service life of the pavement is prolonged; the anti-freezing drainage asphalt mixture surface layer contains a plurality of gaps, and the void ratio of the anti-freezing drainage asphalt mixture surface layer is 15-30%, so that the road has the characteristics of drainage, skid resistance, noise reduction and the like, and has excellent service functions and economic benefits.
一种抗凝冰排水沥青道路，包括：路基层、密级配沥青混合料不透水层以及抗凝冰排水沥青混合料面层，所述密级配沥青混合料不透水层铺设于所述路基层上，所述抗凝冰排水沥青混合料面层铺设于所述密级配沥青混合料不透水层上，所述抗凝冰排水沥青混合料面层内含有若干空隙，若干所述空隙之间相互连通，且所述抗凝冰排水沥青混合料面层的空隙率为15％～30％；与现有技术相比，本发明的有益效果在于：可以有效提高路面的抗凝冰性能，在低温环境下保护路面结构，提高道路实用寿命；由于所述抗凝冰排水沥青混合料面层内含有若干空隙，且所述抗凝冰排水沥青混合料面层的空隙率为15％～30％，使得道路具有排水、抗滑、降噪等特点，具有优良的服务功能与经济效益。
