DETERMINATION OF OPTIMUM BITUMEN CONTENT FOR CDW IN PAVEMENTS

Abstract

Construction demolition waste”(CDW) form the major portion of solid wastes. These waste are deposited into public landfills.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 sub-base and base course is the main objective of our project. The main priority is to foment sustainable construction work, which has the advantage of avoiding the deposit of large quantities of construction waste at landfills and greatly reducing the use of borrow materials in construction projects.Marshall method of mix design gives a clear idea about the optimum bitumen content for the material of construction. It also determines the extend of binding of the CDW with the bitumen. This can help in effectively managing the road construction.
