Abstract
When evaluating rut depth of on-service asphalt pavement with surface cracks, it appears important to take into account the deterioration of base-course material due to repeated loading under water penetration through the surface cracks. This paper presents the results of the model test of repeated loading on crushed stone base-course under water penetration, and discusses the development of settlement and excess pore water pressure and also the formation of softened and deteriorated zone due to finer particles migration during repeated loading.
