The recycling of Asphalt Pavement (RAP) in the production of new bituminous mixtures is an interesting possibility at a time when waste minimization is to the fore. The economic cost of dumping RAP and other waste materials has increased which has led the drive to investigate the recovery of RAP and other materials to reduce their spiraling waste disposal costs. The environmental effects of disposing RAP have posed questions to be asked about the pollution caused to the ground and streams by the leaking of leaches from RAP. The present investigation consisted of experimental and theoretical studies of using various % of RAP aggregate and bitumen in different mixtures. The aggregates & bitumen used have been recycled from bituminous mixtures. The quality and grading of both the RAP and new material was examined and the mix design was altered to produce specimens of the same composition as the base mixtures. Bituminous specimens were produced and Marshall Test was carried. The result showed that RAP could successfully be used in bituminous mixtures up to 30%. The effects of changing in the different volumetric properties of compacted paving mixtures as a result of adding the various amounts of RAP aggregate were examined.
