Abstract
In permeable pavement, base and subbase layers need to meet design requirements capable of supporting traffic loads and providing adequate drainage for road serviceability. With high porosity in structure, open-graded aggregates are considered as a general suitable material for base and subbase layers. Nevertheless, because of few fine-grained particles and high void ratio in open-graded aggregates, load-bearing capacity of pavement may be reduced. Resilient modulus and layer coefficient are two necessary parameters in structural design of pavement. In decades, there were few studies made for base and subbase layers made from open-graded aggregates. The overall objective of this study is to summarize different researches made about the resilient modulus and layer coefficient of permeable base and subbase layers.
