重载车辆对沥青路面结构响应及设计方法的影响

Influence of heavy vehicles on asphalt pavement structure response and design method

通过对重载作用下沥青路面破坏机理的分析,总结出重载车辆作用的路面受力特点、路面结构材料的非线性性质以及重载车辆对路表弯沉及层底拉应力的影响规律;对沥青路面结构的设计方法进行了研究,提出了路面的设计指标,交通参数、土基以及材料参数的选取方法,拟定了重载作用下典型路面结构型式。

Through analysis the asphalt pavement damage mechanism under heavy load, this paper summed up the mechanical characteristics of the road surface and road construction materials nonlinearity under heavy vehicles, the effection of heavy vehicles on surface deflection and layer bottom stress of law ; and study asphalt pavement structure design method , proposed road design specifica- tions, traffic parameters, soil base and material parame- ters selection method, developed under heavy load typical pavement structure type.
