摘要
介绍半刚性基层沥青路面反射裂缝的形成机理,综述半刚性基层沥青路面反射裂缝与各影响因素间的变化规律。影响反射裂缝的因素可分为路面结构材料特性、路面结构温度场特性、路面结构荷载特性、路面结构层之间结合状态和反射裂缝长度等。
Introduced the formation mechanism of reflective cracking in semi-rigid base asphalt pavement, overview the variety regulation of each impact factor of reflective cracking in semi-rigid base asphalt pavement. The factor that influences to reflect crack can be divided into the pavement structures＇ material characteristic, the pavement structures＇ temperature characteristic, the pavement structure＇s load characteristic and the pavement structures＇ built-up to combine appearance and the crack length etc.
