Evaluation of Comparative Damaging Effects of Multiple Truck Axles for Flexible Pavements
| 项目名称： | Evaluation of Comparative Damaging Effects of Multiple Truck Axles for Flexible Pavements |
| 摘要： | The objective of this project is to develop a strain measurement dataset that will allow revisiting pavement response under in-service traffic for the purpose of quantifying pavement damage under various truck/axle configurations. In addition, the pavement layer properties from the instrumented pavement site will allow comparing the measured versus estimated strains using conventional layer visco-elastic techniques. It involves installation of an instrumented site, laboratory characterization of the asphalt concrete properties at the site and finite element method (FEM) simulation of the pavement responses. The outcome will benefit pavement designers and road authorities that levy permit fees for commercial vehicles. |
