不同沥青路面结构抵抗车辙性能理论计算分析

Theoretical Calculation and Analysis on the Rutting Resistance performance of Different Asphalt Pavement Structure

车辙是沥青路面早期损坏主要形式,特别在陡坡及超载的条件下,沥青路面车辙病害更为突出。文章拟定了5种沥青路面结构组成,建立有限元模型计算了各种沥青路面结构的力学参数,对各种路面结构抵抗车辙的性能进行了分析对比。

Rutting is the major damage type on asphalt pavement in early stage.And the rutting defect on asphalt pavement is particularly outstanding under steep slope and overloading condition.In the Paper,five asphalt pavement structures have been assumed,and the mechanics parameters of various asphalt pavement structures have been calculated by establishing finite element model.On the other hand,the rutting resistance performance of various pavement structures has also been analyzed and compared.
