| 摘 要： | 反射裂缝是半刚性基层沥青路面和刚性基层沥青路面的主要病害之一,针对这一问题,提出了采用开级配大粒径沥青碎石混合料作为裂缝缓解层的方法.基于开级配大粒径沥青碎石缓解层沥青路面温度应力的计算原理,以通用有限元软件ABAQUS为基础,对开级配大粒径沥青碎石缓解层沥青路面的温度应力进行分析,探讨了其结构层参数对其温度应力的影响规律.结果表明:开级配LSAM缓解层模量、厚度、空隙率对其自身温度应力具有显著的影响作用,是开级配LSAM缓解层沥青路面结构设计的重要参数. |

| Abstract: | The reflective cracking is one of the main damages of semi-rigid base asphalt pavement and rigid base asphalt pavement.Aimed at this problem, a method that using open-graded large stone asphalt mixture (LSAM) as cracking relief layer was proposed.Based on the calculation principles of temperature stress of asphalt pavement with open-graded LSAM relief layer was introduced, the temperature stress of open-graded LSAM of asphalt pavement was analyzed, and the influence of pavement design parameters on temperature stress was discussed by using finite element analysis software ABAQUS.The result indicates that modulus, thickness and air voids of open-graded LSAM have the remarkable influence on its temperature stress and they are key parameters for the structural design of asphalt pavement with open-graded LSAM. |
