| Abstract: | The pavement surface was imitated by using sine curve, the vehicle vibration model was established, the calculation method of dynamic loads of driving vehicle on unevenness asphalt pavement and the estimating method of pavement evenness under dynamic load ware given. The calculated results were proved to be reliable throuch comparing with actual measured results. This method provides a theory basis for analyzing developing tendency of pavement evenness, and gives a technical supporting for the appreciation of performance and maintenance of asphalt pavement. |
| Keywords: | vehicle dynamic loads pavement evenness permanent deformation estimation |
