Rutting Performance of Road Using Construction and Demolition Waste Materials

摘要

Wastes arising from construction and demolition (C & D) constitute one of the major streams in several countries. In this paper experimental investigation was carried to see the feasibility of C& D waste as road aggregates. From the grading analysis it was observed that using C& D wastes, strength criteria is being satisfied and meet the specifications of MORTH which is then subjected to aggregate impact value (AIV) testing, CBR testing, etc. The CBR value of C&D waste was found to be 43.46 which were well above the permissible value. A proposed three-layer system using soil layer, C & D waste layer and asphalt concrete layer is chosen to estimate rut depth using existing analytical model. From the analytical model rut depth is predicted to be 14.77 mm which is less than the maximum allowable limits. Hence, C& D waste materials can be used in road construction as alternate materials, with economy and sustainability.
