The invention discloses an anti-freezing wearing layer and a maintenance construction method of an asphalt pavement. The anti-freezing wearing layer comprises special aggregate for the anti-freezing wearing layer and special emulsified asphalt for the anti-freezing wearing layer, and the special aggregate for the anti-freezing wearing layer comprises basalt, a temperature-sensitive anti-freezing agent, filler, Portland cement and water; the special emulsified asphalt for the anti-freezing wearing layer comprises petroleum matrix asphalt, an emulsifier, a modifier, an emulsified asphalt charge regulator, an emulsified asphalt viscosity regulator and water. The special aggregate for the anti-freezing wearing layer is added with the temperature-sensitive anti-freezing agent, effective components can be normally released in a low-temperature environment in winter, the release rate of the effective components in high-temperature seasons in spring, summer and autumn is greatly reduced, the effect of the anti-freezing agent is guaranteed to the maximum extent, the service life is prolonged, meanwhile, the thickness of the anti-freezing wearing layer is small, the paving cost is relatively low, and the anti-freezing rigid requirement of the pavement in the service period can be met.
本发明公开了一种抗凝冰磨耗层及沥青路面的养护施工方法，其中抗凝冰磨耗层包括抗凝冰磨耗层专用集料和抗凝冰磨耗层专用乳化沥青，抗凝冰磨耗层专用集料包括玄武岩、温感型抗凝冰剂、填料、硅酸盐水泥和水；抗凝冰磨耗层专用乳化沥青包括石油基质沥青、乳化剂、改性剂、乳化沥青电荷调整剂、乳化沥青黏度调整剂和水。本发明抗凝冰磨耗层专用集料添加温感型抗凝冰剂，在冬天低温环境下可以正常释放有效成分，而在春夏秋高温季节有效成分的释放速率大大降低，最大限度地保证抗凝冰剂的作用，延长使用年限，同时抗凝冰磨耗层厚度薄，加铺成本相对较低，能够满足服务期内路面抗凝冰的刚性需求。
