An increase in demand for aggregates and environmental and economic concerns over the disposal of waste has led to an interest in the use of recycled materials for construction purposes. Many recycled materials have the potential for use in construction but little research has been carried out into their performance. This paper identifies some of the properties of waste glass which suggest possibilities for its use in geotechnical situations. Three samples of crushed waste glass are tested for permeability, shear strength, crushing resistance and small-strain stiffness and the results show that the glass samples have the potential to perform as well as gravel.
