Economic Construction of Bituminous Road by Utilization of Waste Tyre Rubber – CRMB | IJSTE JOURNAL VOL 1, ISS 12
Economic Construction of Bituminous Road by Utilization of Waste Tyre Rubber – CRMB The objective of this research is to find a good mix proportion for the rubberized bitumen. Flexible pavements with bituminous surfacing are widely used in India. The high traffic intensity in terms of commercial vehicles, over loading of trucks and significant variations in daily and seasonal temperature of the pavement have been responsible for earlier development of distress symptoms. Investigations in India and abroad have revealed that the properties of bitumen and bituminous mixes can be improved to meet the basic requirements. Use of Crumb Rubber i.e. the rubber obtained from the waste tires of vehicles, is used in the construction of flexible pavement. In the present study, an attempt has been made to use crumb rubber modified bitumen which is blended at specified temperatures. Marshall’s mix design was carried out by changing the modified bitumen content at constant optimum rubber content ...
