Abstract
Abstract: The expansion in infrastructure due to the building and demolition operations, more construction and demolition waste are produced and this waste must be properly disposed of and managed. This paper proposes to evaluate the feasibility of using construction and demolition waste (CDW) for the subgrade of roads. The subgrade material is fully replaced by the finer portions of CDW and its practicality is analysed. The properties were identified by conducting compaction, direct shear, CBR etc. The properties of finer portions of CDW were compared with the basic requirements of subgrade material. The results indicated that the subgrade material can be fully replaced by finer portions only after suitable modification of CDW.
