| 摘 要： | 基于重载,通过室内试验,采用考虑运动车辆与不平整路面相互耦合作用的更加符合实际的汽车动载模型而建立起来的具有较高精度的车辆动力作用下沥青路面车辙计算与预估的方法,对大碎石柔性基层的抗车辙性能进行研究;并通过试验路的跟踪观测对试验成果和三维动载数值计算结果进行了验证.结果表明,重载作用下车辙主要是由横向剪切引起的,采用低标号沥青、压碎值小的优质集料和合理级配的大碎石柔性基层路面的抗车辙能力并不比传统的半刚性基层沥青路面差. |

| Abstract: | The rut-resistance properties of large-stone flexible bases are studied,taking into consideration heavy loads and using computer simulation and numerous indoor tests.In computer simulations of large-stone flexible bases,a calculation method was formulated for predicting asphalt pavement rut under dynamic loads.The method was based on the coupling of vehicle dynamic loads and pavement surface unevenness.The results of indoor testing and three-dimensional numeric calculation under dynamic loads are confirmed ... |
| Keywords: | large-stone flexible base rut heavy loads computer simulation dynamic loads test road |
