Abstract
Removed and / or reprocessed pavement materials containing asphalt and aggregate are termed as Reclaimed Asphalt Pavement (RAP).These materials are generated when asphalt pavements are removed for reconstruction and/or resurfacing of bituminous roads. When scraped or removed RAP properly screened and crushed, it consists of high quality well graded aggregate coated by asphalt cement. Recycling of asphalt pavement makes both environmental and economic profits. Presently use of recycled asphalt pavement has grown worldwide, reducing use of virgin materials thus becoming Technique of Sustainable Development. The objective of this review is to understand the scenario of using RAP in road construction basically in reference to India; learning from developed countries and other nations where use of RAP is in Advance stage.
