摘要
过量超载的车辆是造成山区公路沥青路面开裂、凹陷、唧泥、使用寿命骤减的主要原因。以S216线和田～布雅段(K70～K90)为例,对该路段沥青路面进行路况调查、钻芯取样试验、实际交通量分析、路面各层弯拉应力、剪应力验算,并提出防止损坏的措施。
The excessive amount of overloading of vehicles is the main reason why the mountain road asphalt pavement had cracks,dents,mud pump and service life decrease sharply.The paper took Hetian-Buya section（K70 - K90） of Line S216 as an example and traffic surveys,core sampling tests,analysis of actual traffic volume,road bends all levels of tensile stress and shear stress check were carried out and the paper suggested some measures to prevent damage.
