PERMEABILITY IN MALAYSIAN HOT MIX ASPHALT

Many studies have shown that the air void content affect the permeability of the hot mix asphalt (HMA) mixtures. This study aims to evaluate the characteristic of local HMA mixtures and find a relationship between air void and permeability, and then obtain in-situ minimum density level in order to produce impermeable pavements.
