Utilization of building waste in road construction

Abstract

Roads are major consumers of aggregate and the influence of aggregate cost is more in total construction cost of the roads. In order to reduce the cost of construction of roads, the possibility of using building waste as aggregate in subbase and base course has been studied. Experimental studies were carried out to determine the engineering properties of the recycled aggregate and compared with conventional aggregate. It has been observed that the building debris can be effectively used as road material as it is satisfying the MoRTH (ministry of road transport & highways) requirements. Brick aggregate was found to be relatively soft compared with other recycled aggregate which may be used as sub-base course.
