机械经验建模和设计解决方案已被常规用于传统的柔性路面，最近通过AASHTO设计软件的发行进入主流设计实践。最近的工作已经完成，将与土工合成材料的基础加固机制纳入机械经验建模和设计。本文的目的是研究使用这项工作的机械经验建模的钢筋未铺装道路，使用相同的模型组件用于铺装道路，并纳入新的组件，占路基中产生的孔隙水压力的显着影响。未铺设路面测试路段的测试结果用于校准和比较模型的预测。该模型提供了合理的预测车辙行为的试验路段车辙发展是稳定的，稳定的定义为车辙率，随着交通量的增加而减少。过量孔隙水的重要性
AbstractMechanistic-empirical modeling and design solutions have been routinely used for conventional flexible pavements and have recently entered mainstream design practice through the issue of AASHTO design software. Recent work has been performed to incorporate mechanisms of base reinforcement with geosynthetics into mechanistic-empirical modeling and design. The purpose of this paper is to examine the use of this work for mechanistic-empirical modeling of reinforced unpaved roads by using the same model components used for paved roads and incorporating new components that account for the significant influence of pore-water pressure generation in the subgrade. Results from instrumented unpaved road test sections are used to calibrate and compare with the model predictions. The model provides reasonable predictions of rutting behavior for test sections where rut development is stable, where stable is defined as a rate of rutting that decreases with increasing traffic. The importance of excess pore-water...
