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。这表明抗疲劳层的设计对于整个路面的力学特性影响很大。
Based on the concept of long-life pavement, the function of each layer of long-life pavement is analyzed. The mechanical properties of anti-fatigue layer are analyzed by orthogonal analysis method. After calculation and analysis, the effects of anti-fatigue layer thickness and modulus on pavement deflection and The anti-fatigue layer bottom tensile strain has little effect, but it has a great influence on the tensile tensile strain of the asphalt stabilized base layer. This shows that the design of the anti-fatigue layer has a great influence on the mechanical properties of the entire road surface.
