Abstract

Abstract

Permeability test was done at three expressways in 2001. Based on the test data, it is concluded that permeability of asphalt pavement is affected by mixture type, in place air void, thickness of layer and surface structure; coarse mixture is more permeable to water than dense one with the same in place air void. Increasing in place air void and surface structure can cause larger permeability; thicker pavement is less permeable to water; permeability should be worked as a quality control index, and a suggested control value is given based on the statistical analysis.
