摘要
针对沥青路面早期的破坏问题,通过对西柏坡高速公路高庄至北沟段平山连接线路面的破损状况与病害特征进行调查,并基于马歇尔试验、层间剪切试验、抽提试验以及无侧限抗压强度试验,对原有路面结构性能进行测试与评价,在此基础上系统研究沥青路面早期破坏原因,为确定合理的道路养护方案提供可靠依据。
For the problems of asphalt pavement＇s early damage, the damage condition and disease characteristics of an actual project located in Hebei Province were surveyed. The Marshall test, interlayer shear-strength test, extraction steam turbine test and unconfined compression test were conducted to evaluate the structural performance of pavement, based on which the reasons of early damages shown on asphalt pavement were studied, which provides a reliable basis for scheduling reasonable road maintenance.
