Abstracts: The problem arising from continuous technological and industrial development is generation of waste material which causes great impact on the environment. This utilization of waste would not only make construction and production economical, but may also control environmental crisis that is pollution and depletion of natural resources. Coarse aggregates are an integral component of flexible pavements. Various sizes of coarse aggregates like 40mm, 20mm, 10mm, stone-dust etc are used in various layers of flexible pavements. Coarse aggregates that go into the construction of various RCC structures form a part of the waste materials that are produced after the demolition of those structures. These waste aggregates, which are in the form of concrete chunks adhered with hardened cement, can be used as a replacement to the conventional aggregates in the flexible pavement construction after proper recycling. In this experimental investigation the waste aggregates are first recycled and then added to the bituminous macadam as a replacement to conventional aggregates. These recycled aggregates are to be tested to know their physical properties so that they can successfully replace the conventional aggregates. This project also deals with the study of entire mix designing of layers of the flexible pavement as well as a case study on the construction process of the pavement on black cotton soil.
