Rutting Model Considering Shear Behavior of Asphalt Pavement

摘要

摘要: 为向路面结构设计和沥青混合料抗剪设计提供参考,用室内环道试验数据建立了基于抗剪性能的车辙预估模型,并与现有车辙预估模型进行了比较.为了标定该车辙预估模型,采用2条高速公路沥青路面现场实测数据,对车辙预估值和实测值进行了比较.结果表明:与现有车辙预估模型相比,除综合系数有差别外,其余参数值相差较小;当修正系数为0.361 3时,预估值和实测值吻合较好.

Abstract: To provide a reference for the design of asphalt pavement, a rutting model considering shear behavior of asphalt pavement was established using the observed data from a circular road test, and this model was compared with the current rutting models. To verify the established rutting model, data observed from two expressways was used to analyze the relationship between the predicted and observed rutting values. The comparison result shows that compared with the current rutting models, the established rutting model is more satisfactory, and when correction factor is 0.361 3, there is a good match between the predicted and observed rutting values in the two expressways.
