摘要
根据载货车辆占交通量比例数据统计分析,目前宁夏运输车辆超载对路面损坏程度日趋严重.通过汽车超载对路面设计弯沉值、层底拉应力及其他方面的分析,论述了超载车辆对沥青路面的影响及路面早期破坏的成因,提出在路面设计中应注意采用优化路面设计;在施工中应保证路面的压实度,并应加大对超载车辆的治理力度.
By analyzing the statistics of proportion in overloading vehicles in Ningxia road transportation at present, due to overloading, the damage to the road surface increases at geometric series times, and this is also the main reason for forepart damage of the asphalt road surface. Through studying the designed road surface curve and sink value, bottom stress and other aspects due to overloading, the paper found the effect of overloading to the road surface, and brought forward several reasonable suggestionsas follows： to optimize the road surface design, guarantee the compress degree of road surface, and to strengthen the management of overloading vehicles, etc.
