Abstract
The present invention relates a novel approach to prepare Polymer Modified Bitumen by using terephthalamide additives, derived from PET, for improving bitumen quality. Particularly, the present invention provides a process to utilize waste PET, which is a threat to environment and is available commercially in different physical forms, for conversion into industrially useful additive for bituminous product.
