Comparison of Stability and Volumetric Properties of Conventional and Stone Mastic Asphalt

Abstract

Stone Mastic Asphalt (SMA) and Conventional Mix Asphalt (CMA) are the two common pavement materials, with their peculiarities influencing their high effectiveness, high stability, and long life. In the present investigation, we examine these two materials' resilience and volumetric properties under varying conditions, focusing on the structural and material differences that make SMA suited to high-traffic applications. In the laboratory, we use the Marshall Stability Test to analyze vital traits of rut resistance, aggregate structure, and binder content. Our results show that SMA with high stone content and superior AC binder stability has about twice the rut resistance and durability than CMA and is an appropriate solution for highly traveled roads. In this study, the current research is based on data investigating the benefits of SMA in enhancing pavement life, particularly in heavy vehicular load areas.
