Abstract
Abstract: Utilization of recycled materials in DBM mixes is gaining popularity due to environmental concerns and the potential for cost savings. The performance of DBM is influenced by several factors, including the choice of binder grade and the incorporation of recycled materials. However, the impact of recycled materials on the mechanical properties of the mix, as measured by Marshall stability and indirect tensile strength, needs to be thoroughly understood. Although the effect of RAP addition in DBM has been studied in relation to the Marshall test but not much is known about its effect on Indirect Tensile Strength. Marshall Stability and ITS have alone been the subject of several research investigations, but their combination has received far less attention. The correlation between Marshall Stability and ITS was researched to some extent for virgin mixes but not with recycled material. An effort has been made to examine their correlation in this study. This study aims to explore the potential benefits of incorporating RAP in DBM mixes and how it affects the correlation between the two parameters.
