Abstract

Reclaimed Asphalt Pavement (RAP) is a popular recycled material used in the construction of pavements. In contrast, incorporating RAP into asphalt mixtures is a complex process that involves a thorough understanding of all aspects of the mix design. The purpose of this review paper is to provide a comprehensive analysis of asphalt mixtures containing RAP. Based on this study and previous research papers, it is possible to conclude that using RAP is advantageous because RAP mixes can produce results that are equal to or even better than virgin mixes. The specifications and mix design followed the MORTH 5th revision for dense bituminous macadam grade II mix. The Marshall properties were obtained, which includes bulk density, flow stability, voids in mineral aggregates, and an air void filled with bitumen. RAP mixes have a positive effect on a number of parameters including Marshall Stability, Indirect tensile strength and rutting. This study provides information about RAP technology to the designers, engineers and researchers.

Keywords
