Recycled Sands from Demolition Wastes as a Natural Sand Substitute Material in Pavement Construction

Abstract

The accumulation of construction and demolition (C&D) waste in landfills is deemed a worldwide concern which is exacerbated by the impact of rapid urbanization and increased construction activities. The massive amount of waste disposal and increased demand for non-renewable virgin quarry materials such as natural sand triggers the urgent need to adopt various kinds of recycled materials in geotechnical fields, such as washed recycled sand (RS). Washed RS reviewed in this study is derived from C&D waste at a local washing plant in Melbourne, Victoria. Two types of washed RS were used as the target materials in this research based on their ranges of particle size: coarse recycled sand (CRS) an..
