I've engaged Allens Asphalt to perform all types of asphalt and sealing works on our construction sites for over a decade now, and will continue to utilize these guys in the years to come. No problem can't be resolved with the help of their experienced staff.
Open Graded Asphalt
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 per cent) to allow surface water to drain away and hence increase safety for the motorist.
The demand for low traffic noise surfacing has greatly increased in the last few years, especially in urban areas.

Features & Benefits
- Low traffic noise surfacing for roads in urban areas.
- Australian open graded asphalt mix designs reported to reduce 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 in wet weather and reduced noise levels.
- Large voids in porous asphalt mix allow drainage of surface water for increased safety in wet weather.
