Evaluation of pavement materials for Dense Bituminous Macadam layer using Reclaimed Asphalt Pavement (RAP)

Abstract

As a sustainable and eco-friendly alternative to fresh or new materials for road construction and maintenance, recycled or reclaimed asphalt pavement (RAP) is being used more frequently. There are no specific criteria, norms, or methods for identifying recovered asphalt materials in India or other developing nations. Classifying the RAP materials that are now accessible for use in road construction is therefore urgently necessary. Costs associated with highway projects can be cut by 25–30% by reusing these materials. There have been some reported studies in India where new materials were swapped out for RAP in the binder course, but there are undoubtedly many more that have not yet been documented. The goal of the current experiment is to determine the aggregate mix percentage for DBM layers with various percentages of RAP. The RAP sample was taken from the NH209 Kanakpura Road.
