Knowing that Allens Asphalt have been successfully servicing local councils in the SEQ area for over 25 years, we are always pleased when we hear that Allens have successfully tendered for one of our local projects. We have great relationships with their people, and this goes a long way in getting a project completed without the usual headaches that can come with roadwork projects. The communication between both parties is always top notch. Great group of people.
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.
- Car park
- Council roads
- State roads
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.
- Hot mix
