Utilization of Eggshells Ash as Additive in Enhancing Physical Properties of Bitumen Binder

Abstract

The aim of this research is to evaluate the physical properties of bitumen binder incorporating eggshell ash (ESA). Using ESA in bitumen was investigated as an alternative, as an additive in potential paths to landfill disposal and for improving the service physical properties of bitumen binder. Four different contents of ESA (2%, 5%, 7%, and 10%) were used by weight of bitumen with a 60/70 penetration grade. Several laboratory tests, i.e., penetration, softening point, ductility, viscosity, and specific gravity, were conducted to check the performance of the ESA. The results showed that the specimens with higher ESA content had the largest values of softening point. In contrast, the softening point decreased as the ESA content decreased. The addition of ESA clearly shows the increase in viscosity. From the observations, it is evident that the addition of 5% of ESA has the potential to improve the performance of bitumen binder compared to other ESA percentages.

“…The road infrastructure construction industry is of paramount importance on a global scale, as it has a substantial impact on economic development. However, the process of constructing and maintaining roads can lead to significant environmental consequences that include resource consumption, energy usage, and greenhouse gas emissions [1]. As a result, there is an increasing demand for environmentally sustainable approaches in road infrastructure construction to effectively tackle these ecological challenges [2].…”
