Deterioration modelling of flexible pavements with modified bitumen in wearing course

Abstract

India is developing its highway infrastructure through widening and rehabilitation of existing national highways under different phases of National Highway Development Program NHDP The NHDP road network is considered as a high speed road corridor of India Use of modified bituminous binders have increased manifold in the last decade in India mainly in the bituminous concrete BC hot mix asphalt wearing course of flexible pavements Because of their enhanced engineering properties modified
