: The study has been undertaken & investigate white topping is rehabilitation treatment on asphalt concrete. It is defined as plain cement concrete overlay on asphalt concrete. It provides a new innovative method of rehabilitation at a very low cost with very good results and low maintenance cost. By adopting proper construction methods, we can rehabilitate large network of roads at reasonable cost and we get additional long life. This project presents a methodology to adopt white topping as rehabilitation treatment and cost-effective rehabilitation alternative for preserving bituminous pavements on long-term basis. Ultrathin white topping (UTW) is a concrete overlay of a distressed asphalt pavement, 50 to 100 mm thick, with close joint spacing. The overlay is specifically bonded to the existing asphalt pavement. It may or may not contain fibers. By bonding the UTW to the existing asphalt surface, the UTW forms a composite pavement section with the under- lying asphalt, which reduces the stresses in the concrete layer. This composite pavement section delivers the longer life and durable performance characteristics of concrete pavement and is cost competitive with ordinary asphalt. In addition, rapid developments in concrete material technology and mechanization are favoring concrete overlays as a sustainable option. White topping is gaining momentum in road construction across the country. It can act as a long-term alternative for the rehabilitation or structural strengthening of roads.
