| Boral Asphalt Open Graded Asphalt (OGA) |
 |
• industry and community accepted surface treatment used on major metropolitan facilities
(Eastlink) for its noise attenuating properties
• low traffic noise - surface reduces average noise levels by up
to 3dB(A) compared to
Dense Graded Asphalt and up to 5dB(A) compared with Spray Seals
• wearing course provides increased safety for motorists in wet weather - porous asphalt mix
formulated to provide large voids (in excess of 20%) to allow surface water (and spray
during rain) to drain away.
