不同沥青路面结构温度场研究

Reserch on The Temperature Field of Different Asphalt Pavement Structures

借助有限元软件ABAQUS对浙江杭千高速桐庐试验段组合式沥青路面结构进行温度场分析,并与现场路面实测温度场进行对比,发现采用有限元数值方法模拟沥青路面结构温度场是可行的。对选定的3种不同基层沥青路面结构,包括常规半刚性基层沥青路面结构、采用沥青稳定碎石和级配碎石的柔性基层沥青路面结构以及柔性基层与半刚性基层相结合的组合式基层沥青路面结构进行了温度场的对比分析。

Firstly, with the finite element software of ABAQUS, there was an analysis for the temperature field of the Composite Base asphalt pavement structure in the tong-lu test load of hang-qian highway in ZheJiang province, then a contrast to the road-test temperature field, The study indicated that the finite element was feasible in the analysis for the temperature field of asphalt pavement structure. Secondly, there was an analysis and contrast to the temperature field for the three chosen different asphalt pavement structures, included the general semi-rigid asphalt pavement structures, the flexible base asphalt pavement structure with asphah-stabilized stone or graded crushed stone as base, and the composite base asphalt pavement structure with composed of flexible base and semi-rigid base.
