不同半刚性基层参数对沥青路面的影响分析

Study on the Effect of Different Parameters of Semi-rigid Base Course on Asphalt Pavement

利用有限元法,研究分析不同半刚性基层参数对沥青路面的影响。结果表明:适当增加半刚性基层厚度、底基层厚度和底基层模量,可以提高路面的力学性能和使用寿命。所得结论对实际的工程施工有一定的指导作用。

With the finite element method, the effect on asphalt pavement with changing the thickness and modulus of semi-rigid base course was studied. The results show that the mechanics function and the using life of asphalt pavement can be improved through properly increasing the thickness of semi-rigid base course and increasing the thickness and modulus of bottom base course. The conclusions are helpful to practical construction.
