- The use of layered recycled aggregate concrete barriers in targeting urban noise
- Krezel, Zbigniew A.; McManus, Kerry J.; Harding, Graeme E.
- Transportation noise has become an increasing major issue of modern urban life and at the same time the financial, environmental and social consequences of construction and demolition waste, especially concrete waste, have become less tolerated by the community. The Infrastructure Service Management Research Group (ISMRG) at Swinburne University of Technology investigated the use of selected recycled and reclaimed (washed) concrete aggregate in the production of sound barriers. Three prototype barriers were manufactured using both recycled and reclaimed aggregate. The resulting barriers consist of either two or three layers that provide structural adequacy and enable the barrier to restrict sound transmission and absorb transportation noise. Impedance tube and reverberation chamber test results of the barrier material indicate satisfactory acoustic performance of the barriers in the low and mid frequency range and excellent sound absorbency at frequencies above 1,000 Hz. Strength and durability test results of recycled and reclaimed aggregate concrete meet specified requirements. The paper also presents an assessment of the acoustic performance of the acoustic barriers as a means to attenuate road traffic noise, as a means of reducing reverberation and providing sound absorption in transformer rooms, as a means of reducing noise coming out of traffic tunnels and as a means of lessening of noise from railway tracks.
