长寿命沥青路面抗疲劳层力学特性分析

从长寿命路面的概念出发，分析了长寿命路面的各层功能，并利用正交分析方法分析了抗疲劳层的力学特性，经过计算分析，抗疲劳层的厚度和模量对路面弯沉和抗疲劳层层底拉应变影响不大，但是对沥青稳定基层层底拉应变影响很大，从而论证抗疲劳层的设计对于整个路面的力学特性影响很大。

Mechanical characteristic analysis of anti-figure layer in long-term asphalt pavement

The paper commences on concept of long-term pavement, analyzes all layers＇ function of long-term pavement, and analyzes the mechanical characteristic of the anti-figure layer based on the orthogonality analysis method, according to the calculation and analysis, results prove that the thickness and the modulus of the anti-figure layer has little influence on pavement deflection and the layer bottom tensile strain of the anti-figure layer, but has large influence on asphalt stabilizing foundation bottom tensile strain, thus proves that the design of the anti-figure layer has large influence on the mechanical characteristics of the whole pavement.
