- Current levels of natural aggregate production are under threat due to fast diminishing resources for virgin aggregates. Under this circumstance, waste materials may be recycled to be used as an alternative material in pavement as base/subbase material. Hence, there is now a developing emphasis on environmental management which has resulted in growing pressure to investigate the viability of reusing of all categories of waste materials. Recycled glass is a waste material produced in large quantities in municipal and industrial areas in Australia and worldwide. Currently in the state of Victoria, Australia, 186,000 tonnes of recycled glass is stockpiled annually and this figure is growing every year. To date, there is little known reuse of recycled glass in pavement subbase applications due to limited knowledge concerning its geotechnical properties. The reuse of recycled glass in road pavement applications will provide the opportunity not only to eliminate the waste glass stockpiles and minimize the use of virgin materials in pavement applications but also to minimize the valuable land being used for landfilling. This paper discusses the properties of recycled glass when used in blends of up to 50% with crushed rock in pavement subbase applications. Laboratory geotechnical tests discussed in this paper include modified compaction, Los Angeles abrasion loss, triaxial compression tests and California Bearing Ratio (CBR) tests. The findings of this research indicate that initially up to 30% recycled glass with the maximum particle size of 4.75 mm could be safely added to crushed rock when used in pavement subbase applications.
