摘要:

采用移动荷载下黏弹性层状体系动力学模型,分析加厚式半刚性基层结构、改进型半刚性基层结构、倒装式路面结构和全厚式路面结构等4种典型沥青路面结构在标准荷载工况和超载100%工况下的动力响应,研究各种路面结构之间差异.结果发现,面层底部水平剪应变对路面结构使用寿命影响最为严重.

Abstract:

The dynamic response of four typical asphalt pavement structures, including thickened semi-rigid base structure, improved semi-rigid base structure, flip-mounted pavement structure and full-thickness pavement structure, under standard load conditions and overload 4% working conditions was analyzed by using the dynamic model of viscoelastic layered system under moving load, and the differences between various pavement structures were studied. The results show that the horizontal shear strain at the bottom of the surface layer has the most serious impact on the service life of the pavement structure.
