Abstract : 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 and subsequent tests have been performed to determine the different mix design characteristics
and for conventional bitumen (VG-30) also. This has resulted in much improved characteristics when compared with straight run
bitumen, due to improved strength of Modified Bitumen it is one of the upcoming important construction materials for flexible
pavements. This study will have a positive impact on the environment as it will reduce the volume of rubber waste to be disposed
of by burning and land filling. It will not only add value to rubber waste but will develop a technology, which is eco-friendly.
