Quality aggregates for pavements are becoming in short supply and new techniques to evaluate the behavior of these materials is needed. This project will develop a realistic structural response model for granular pavement layers. The model will be based on conditions at near failure stress states. Laboratory experiments will be performed dynamically and the behavior of the pavement granular layered sections will be studied to correlate the mathematical model.

用于路面的优质集料正变得供不应求，需要新的技术来评估这些材料的性能。该项目将开发一个现实的颗粒状路面层的结构响应模型。该模型将基于接近破坏应力状态的条件。室内试验将动态进行，并将研究路面颗粒状分层路段的行为，以关联数学模型。
