摘 要: | 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。

Abstract: | Begining with the conception of Perpetual Bituminous Concrete Pavement,the layers of Perpetual Bituminous Concrete Pavement and the mechanics of fatigue-resistant layer are analyzed by the help of orthogonal analysis.The analysis shows that there are little influence of the thickness and modulus of fatigue-resistant layer on pavement deflection and tensile stress in the bottom of the fatigue-resistant layer,however,which greatly affect the change of the tensile strain in the bottom of the bituminous stability layer.It shows that there are great influences of the design of fatigue-resistant layer on pavement mechanics performance. |
