semi-rigid base course asphalt pavement 半刚性基层沥青路面
As primary stiffness, poor water permeability, reflective cracking of pavement surface layer. Traditional semi-rigid base asphalt pavement are easy to premature fatigue cracking phenomenon.
传统的半刚性基层沥青路面，由于基层刚度大、透水性较差，面层反射裂缝多，路面易过早发生疲劳开裂现象。
Firstly, the paper analysed the formation mechanism of the fatigue crack in asphalt pavement with semi-rigid base.
首先，论文分析了半刚性基层沥青路面疲劳裂缝的形成机理。
Unbound aggregate base can efficiently retard the reflexion of cracks to asphalt pavement surface, which is aroused by the shrinkage crack of semi-rigid base in the inverted structure.
半刚性基层沥青路面作为过渡层时，可以有效改善半刚性基层收缩裂缝的反射裂缝的发生。
