The main objective of this research is to investigate the possibility of utilizing construction & demolition waste aggregate in rigid pavement construction. In the present study compressive strength of concrete at 7, 14, and 28 days was checked, and this concrete is prepared by mixing cement, sand, aggregate, and water. In a further study, coarse aggregate is replaced by aggregates obtained from C&D (Construction & Demolition) waste, and then M35 mix design concrete is prepared. From the result obtained in the present experimental investigation, it was found that the desired strength concrete can be obtained from replacing the conventional coarse aggregate with recycled aggregate obtained from C&D waste with a substitution rate of 20 %. Thus the use of C&D waste in concrete manufacturing will not only solve the problem of availability of material but also reduces the cost of the construction and problems caused due to dumping of C&D waste.
