OPEN GRADED ASPHALT SURFACING INTRODUCTION Open Graded Asphalt (OGA) is a porous asphalt material that produces a highly textured surface. It provides a safer wet weather surfacing by reducing the amount of surface water leading to improved visibility and skid resistance. It also generates lower tyre noise compared to other bituminous surfacings.
