The Different Road Surface Structure Combination Stress Contrast Analyse under the Axis Load

Abstract:

Based on the multi-layer elastic system theory , a large general used finite element software is used to analysis in the paper. To the asphaltum concrete surface layer pavement structure, the basic layer shares more load for surface layer along with the basic layer rigidity increasing. To the cement concrete surface layer pavement structure, the basic layer shares less load for surface layer along with the surface layer rigidity increasing. Whichsoever, the soil ground equivalent stress below subgrade 2m deep is almost not affected from the pavement structure layer rigidity change, but it will increase with the load increasing.
