Description

Open Graded Asphalt used in Australia and overseas as a wearing course to provide increased safety in wet weather (through reduced surface water and spray during rain) and reduced noise levels. Open Graded Asphalt is a porous asphalt mix formulated to provide large voids (in excess of 20%) to allow surface water to drain away and hence increase safety for the motorist.
