Geotechnical properties of lightly stabilized recycled demolition materials in base/sub-base applications

Abstract

Conventionally, high quality quarry materials are used for base and sub-base materials of the pavements. Traditional road building materials are becoming scarce in some regions. Moreover, rate of consumption of high strength aggregates is increasing rapidly in different industries. The use of traditional quarry materials at current rate of consumption is unsustainable from both environmental and cost perspective. The engineering characteristics of various cement-treated recycled Construction and Demolition (C&D) materials obtained from extensive laboratory testing are presented in this paper. Unconfined Compression Strength (UCS) tests shows that cement treated recycled material can be consi..
