Stress Response Analysis of Asphalt Pavement under Measured Tire Ground Pressure of Light Vehicle

Currently, it is very different from actual condition, in the most research and calculation of pavement mechanics, that mode of tire ground pressure is assumed, especially when it is simplified as circular and uniform load. In this paper, the mechanics response of asphalt pavement under different tire type of light vehicle with different air pressure and loads were calculated using the measured date by the author. Results of this study show that the tire ground pressure is non-uniform distribution obviously which is different with the different of tire type, tire texture, tire air pressure, tire load, and age of tire and that the stress response caused by the difference should not be neglected.
