摘要
结合《公路沥青路面设计规范》(JTGD50-2017)对交通荷载参数的要求,通过收集安徽省多条高速公路主线收费站称重数据,采用均值法确定车辆类型分布系数、满载车比例、当量设计轴载换算系数等参数的当地代表值,并通过对比三个水平对路面结构损伤的影响,证明代表值选取的合理性。
Combining with the requirements of traffic load parameters in Code for Design of Highway Asphalt Pavement (JTG D50-2017), the local representative values of vehicle type distribution coefficient, full-load vehicle ratio, equivalent design axle load conversion coefficient and other parameters are determined by means of collecting the weighing data of toll stations for several principal lines of expressways in Anhui Province, and the influence of three levels on the pavement structural damage is compared, so as to prove the rationality of representative value selection.
