为探讨高模量沥青混凝土在路面结构中的设置及使用情况,该文利用Bisar3.0软件对高模量沥青混凝土路面结构进行力学响应分析,进而得到了高模量沥青混凝土的合理设置层位与回弹模量。结论表明:高模量沥青混凝土可以有效地提高路面抗车辙性能,并建议设置在中面层,回弹模量取值在2 500~3 500 MPa范围之内,同时,在设置高模量沥青层的基础上不建议缩减面层厚度。
In order to investigate the setting and usage of high modulus asphalt concrete in pavement structure, this paper uses Bisar3.0 software to analyze the mechanical response of high modulus asphalt concrete pavement structure, and then obtains the reasonable setting of high modulus asphalt concrete And rebound modulus. The conclusion shows that the high modulus asphalt concrete can effectively improve the anti-rutting performance of the pavement, and it is recommended to set it in the middle layer with the modulus of rebound in the range of 2 500 ~ 3 500 MPa. Meanwhile, Layers are not recommended to reduce the thickness of the surface.
