Construction and demolition materials such as recycled crushed rock andrecycled glass account for a major proportion of the waste materials present inlandfills in Australia. Using recycled glass and crushed rock in road pavementapplications would significantly reduce the need for quarry-based virgin materials.Furthermore, recycled materials could be used in parts of the country where aggregatesources are scarce. This paper discusses the suitability and applicability of recycledglass when used in blends with crushed rock for road pavement applications.Performance of the blends was measured using an extensive suite of geotechnicalengineering laboratory tests including basic classification tests along with modifiedcompaction, California Bearing Ratio and Los Angeles abrasion tests. Repeated loadtriaxial tests were also conducted on blends. The test results indicated that therecycled glass could be blended with recycled crushed rock by up to 30% by massand provide satisfactory engineering performance to be used as a pavement subbasematerial.
