Abstract

Permeability can be defined as the capacity of porous material to let water flow through its voids that has been associated with the moisture damage occurrence. One of the most common method for reducing the permeability of HMA is polymer modification of asphalt binder. The best polymer combination (plastomer-elastomer) that related with lowest permeability value for both surface layer A and B is 4% PE-1% SBR and 2% PP-3% SBS. By modification with polymer combinations (plastomer-elastomer), the permeability values decrease to 1.49 times for HMA surface layer A and two 2.04 times for HMA of surface layer B when compared with control ones.
