摘要
沥青路面通车使用后,会受到车辆荷载和温度的大量重复作用,当达到一定次数后,就会产生疲劳开裂。本文在对于北方某高速公路的交通情况及气温变化进行调查分析的基础上,对沥青路面的荷载疲劳裂缝和温度疲劳裂缝的形态进行实地调查,对路面结构的受力状态、疲劳性能、影响因素进行分析,分别从材料、结构、交通等方面提出防治对策。
Asphalt pavement will produce cracking owing to be exposed to repeated loading and varidble temperature after putting in use. In this paper, survey was done on types of Loading and temperature fatigue cracking based on the investigation of traffic and temperation varation in one of North china＇s expressway, and the force tender Loading, fatigue performance and affevting fattors of surface strutture were analyzed, the preventing and control measures were put forward according to constmution materials, structure and communication.
