Abstract
Increase in environmental concerns has been leading to develop innovative and eco-friendly ideas to re-use the waste byproducts from industries and domestic use. Waste plastic and waste tyres/crumb rubber considered as solid waste in India which causes environmental pollution. These wastes will be disposed by land filling and incineration which are hazardous. Flexible pavements tend to become soft in summer &brittle in winter due to high temperature variation. Also early development of distress symptoms occur due to heavy traffic loads on such roads. In these circumstances ordinary bitumen is not sufficient to overcome these symptoms. CRMB is special type of bitumen whose properties have been improved by addition of crumb rubber & special types of additives like hydrocarbon material, resins etc. Thus altering the physical properties of bitumen making it more resistant to temperature variations, weather &high traffic load, From practical experiences of asphalt binder with crump rubber offer several benefits to enhance various engineering properties many modifiers such as styrene based polymers, Gilsonite and various oils have been used in asphalt. In this process addition of crmb-55 has been done by replacing bitumen by percentage by weight in varying percentage. Marshall Method of bituminous mix design was carried out. Significant improvement in properties like Marshall Stability, retained stability, has been observed in crumb rubber bituminous mix compared to conventional mix.
