Research Abstract

Permeable asphalt pavements have been used to reduce stormwater runoff from new development. However, considering application of the pavements into heavy traffic roadways, pavement durability is a great concern. In this study, cyclic plate loading tests have been carried out for model pavements simulating permeable asphalt pavements under unsaturated/ saturated conditions to investigate the effect of the combination of high saturation degree by seepage water and repeated loading on the long-term deformational behavior of permeable asphalt pavements. From the test results, regarding deformation of a pavement surface, it was confirmed that the permanent deformation of the saturated models was five or six times larger than that of the models with natural water content regardless of subgrade soil type. As a mechanism of the deformational behavior, in the case the subgrade was cohesive soil, large plastic deformation of the subgrade was a major cause. On the other hand in the case the subgrade was sandy soil, compression of the subbase could be a major cause, considering the test result that settlement of subgrade surface was very small and it did not depend on saturation degree.
