Abstract
Through a finite-element model developed in the ANSYS (engineering simulation software) platform, the stress-strain properties of concrete pavement under dynamic loads were studied and the affecting laws of different speeds on the stress-strain properties of concrete pavement were determined in this paper. Analysis results indicate the significant difference between static loads and dynamic loads on concrete pavement performance and deterioration. Vehicle speed has a significant effect on the stress-strain properties of concrete pavement. Furthermore, slower vehicle speed has a greater effect than faster vehicle speed. This research finding can provide a more accurate grasp of the actual working conditions of concrete pavement, and provide some guidance to the structural design of concrete pavements.
