Abstract - The utilization of waste materials to modify the performance of bituminous pavement is trending globally. The introduction of egg shell powder as a sustainable modifier is the focus of this study in order to achieve the goals of lowering the weight percentile, cutting expenses, and enhancing the economic viability of hot mix asphalt. One of the latest innovations in construction cost reduction is the use of waste materials, one of which is eggshell as modifier.

This research has the interest to introduce the egg shell powder as a sustainable modifier to fulfil the objectives of reducing the weight percentile, reducing costs and improving the economic viability of hot mix asphalt.

This research was conducted performing a number of experimental tests on virgin and modified asphalt by adding egg shell powder (2, 4, 6, and 8%) by weight of asphalt to evaluate the physical properties of asphalt cement as well as the mechanical properties of hot mix asphalt. The results of the study demonstrated a decrease in penetration and the ductility value as well as a valuable increase in flash point versus increasing percent of the waste material. The mechanical tests showed improvement in stability-flow results with increasing egg shell percent. This paper recommends that egg shell can be used successfully for increasing performance of asphalt.
