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.
