PERMEABILITY: IMPLICATIONS IN ASPHALT MIX DESIGN
Water permeability experiments were conducted on three specimens of open textured bituminous macadam. Results confirmed that at high binder contents the permeability is more sensitive to changes in void content than at lower binder contents. From the mix requirements standpoint, it is proposed in this paper that a maximum limit of 0.001 cm/sec be adopted for the permeability of densely graded mixtures to eliminate durability risks and a minimum limit for open graded mixtures of 1 m/day to obtain free drainage characteristics.
