摘要
在对季冻区多条公路调查的基础上,总结季冻区沥青路面早期破坏的主要类型:裂缝、龟裂、车辙、松散、沉陷、泛油、波浪和冻胀翻浆。同时结合季冻区的气候特点,详细分析沥青路面出现早期病害的原因。根据几种病害的成因,从设计、施工、管理和维修养护4个方面提出相应的防治措施。
Based on the data collected from several highways in the seasonal frozen region, several types of asphalt pavement premature failure in the seasonal frozen region were presented in this paper,which included crack,alligator crack,tracking,loosening,settlement,bleeding,ripple markings,frost-heaving,and frothing. Combining with the weather characteristics of the seasonal frozen region simultaneously,the causes of asphalt pavement early failure were detailed.According to the causes of early illnesses of the asphalt pavement,the corresponding preventing measures were proposed according to design,construction,management,and maintenance four aspects.
