Abstract: The most dominant mode of the transport in India is the Road Transport, carrying close to 90% of the passenger traffic & 70% of the freight transport. In India, flexible pavement type of construction is preferred over the rigid pavement type of construction due to its various advantages such as low initial cost, maintenance cost, etc. Therefore, among the surfaced roads, maximum is the contribution of the bituminous pavements. Bitumen has been widely used in India for the construction of flexible pavements for more than a century. Flexible pavements with bituminous surfacing are widely used in India. Exponential increase in traffic, overloading of commercial vehicles and significant variations in daily and seasonal temperatures have shown some limitations in asphalt binder performance and this has led to early developments of distress symptoms like cracking, rutting, raveling, undulations, shoving and pot holing of bituminous surfacing. CRMB is suitable for pavements submitted to all sorts of weather conditions, highways, traffic denser roads, junctions, heavy duty and high traffic sea port roads etc. It is a durable and economical solution for new construction and maintenance of wearing courses. This paper presents a review study of use of Crumb Rubber in conventional Bitumen.
