| 摘 要： | 为探讨沥青路面车辙问题,建立沥青路面三维有限元模型,通过分析高模量沥青混凝土设置在不同结构层位的力学响应,确定出高模量沥青混凝土的设置层位,并进一步分析高模量沥青混凝土中面层模量大小及其厚度对路面结构受力的影响。结果表明:高模量沥青混凝土可显著抑制车辙的产生,并推荐模量控制在2000MPa~2500MPa,厚度控制在5cm~7cm为宜。

| Abstract: | In order to explore rutting at asphalt pavement,this paper establishes a three-dimensional finite element model of asphalt pavement,and determines the set layer of high modulus asphalt concrete by analyzing the mechanical response with its setting layer in different structures.At the same time,it further analyzes the stress influence of modulus and thickness to pavement structure,which is in the middle layer of high modulus asphalt concrete.The results show that high modulus asphalt concrete can significantly inhibit the generation of rutting,and recommends that its control module should be from 2000MPa to 2500MPa,thickness from 5cm to 7cm. |
