Analysis of the effect of overloaded vehicles on asphalt pavement

In this paper, by using the analyzing program on elastic layer structure, the stress on a typical semirigid pavement structure is analyzed and the controlling standard is the strain on the bottom and the deflection on the surface of the pavement. With different kinds of fatigue equations and through the Minner method, the service life and required extending depth of the pavement based on the current traffic situation are gained. The presented results can be used in the design of the pavement's structure which is based on the axleload spectrum.
