Develop quickly along with the keeping on national economy and science technical progress, the high grade asphalt road have already got more and more extensive application as the main form of the road structure. But follow of, the problem that the overload, and the asphalt road broke early is more and more obvious. The overload have become the important factors of shortened the road life.This text makes the simple introduction to calculating and basic development in mechanics of asphalt road general situation and finite element methods first, expatiating the research purpose and meaning.Then the text uses the different asphalt road parameters: the modulus, the pavement thickness and asphalt road responds: establishes the cartwheel models of load and the asphalt road models of finite element. Apply the finite element theories to the research of respond in the vehicle and the road .And research the distribute regulations of the asphalt road stress and strain under the non-uniform distribution over-load .Then calculating the pavement deflections, the roadbed underside stresses, the sub-roadbed underside stresses, analyzing the asphalt road regulations to the influence of each pavement parameters .Finally,through a textual research to explain the over load has increased the mechanics. The over load have a greater bending deformation and compaction deformation. These deformation of the comprehensive would damage the process accelerated, greatly shorten the life of road.
