The Usage of Organic Waste in Porous Asphalt

Abstract Porous asphalt is a mixture of with low proportion fine aggregate to obtain high air void content, which would create water drainage path inside the pavement be channelled into system. Usually, materials used as filler are relatively expensive, such Portland cement and lime, hence, it necessary look for other cheaper alternative materials, organic waste. This study aims determine effect using waste in porous mixtures on Marshall Permeability tests results. The wastes chosen were coffee grounds (7%, 8%, 9%), tofu dregs sawdust coconut fibre (4%, 5%, 6%). this was prepared based Australian Asphalt Pavement Association (AAPA) standard. results showed that best outcome came from 7% mixture.
