沥青路面反射裂缝养护与防治技术

Research on maintenance and prevention technology of reflective crack in asphalt pavement

结合半刚性基层特点,分析了沥青路面反射裂缝的形成机理,从环境因素、原材料质量、施工过程和养生管理等方面分析了反射裂缝的成因,并重点阐述了反射裂缝养护修补技术,提出了防治措施。

Based on the characteristics of semi-rigid base layer,the formation mechanism of reflective cracks on asphalt pavement is analyzed.The causes of reflective cracks were analyzed from the aspects of environmental factors,raw material quality,construction process and health management,and the reflection crack repair and repair technology was elaborated,and the prevention and control measures were put forward.
