Compaction testing of recycled glass blended with recycled crushed concrete for footpath applications

Abstract

As recycling continues to grow by means of utilizing waste materials in today’s world, more markets must be established for products containing recycled materials. Currently in the state of Victoria, Australia, 200,000 tonnes of recycled glass are being stockpiled annually and these stockpiles are growing day to day. The use of recycled glass in applications such as footpaths is an effective way of disposing them and would also significantly minimise the need for quarry based virgin materials. This paper discusses the compaction and California Bearing Ratio (CBR) results of recycled glass when used in blends with recycled crushed concrete for footpath sub-base applications. Blends of 10% to a maximum of 50% by mass of recycled glass were tested.
