Presidential Young Investigator Award

由于交通负荷和环境的增加，公路路面正在恶化。环境的影响是不确定的，需要进一步研究。该项目将研究水分对路面性能的影响，如土壤强度和刚度的变化、路基的侵蚀以及冻融造成的破坏。

Highway Pavements are deteriorating due to heavier traffic loads and environment. The influence of environment is uncertain and requires further study. This project will investigate the effects of moisture on the pavement behavior, such as, changes in strength and stiffness of soils, the erosion of the subgrade, and the damage due to freezing and thawing.
