| Abstract: | In view of the pavement roughness, different mathematical models for various forms of moving vehicle load are described, and by regarding the pavement roughness as a sine function and simplifying the vehicle to a two DOF vibration system, the dynamic component of vehicle load caused by pavement roughness and the dynamic amplification factor are analysed. They can serve as basic references for highway pavement design and vehicle pavement dynamic interaction analysis. |
