This paper aims at studying the impact of adding high-density polyethylene (HDPE) on the ¾” hot mix asphalt (HMA). Polyethylene is used as it forms a considerable amount of the existing plastic wastes in the world in general and in Palestine at specific. These plastic materials are used as additives to check the performance and the characteristics and properties of the HMA. Accordingly, six different batches of asphalt concrete (AC) samples are prepared using polyethylene as a percentage of the weight of optimum bitumen in varying proportions (0%, 2%, 4%,6% 8%, and 10%). The performance of the HA mixture is examined by checking different parameters such as stability, flow, air voids, VMA, density, etc. The dry process of binominal mixtures (Marshall Method) is used and the required and needed experiments are carried out according to the ASTM specifications. The results indicate that the addition of high-density polyethylene improves and refines the properties of the ¾-inch HMA considering medium traffic in terms of stability and the remaining Marshall parameters. The optimum plastic content is 4% by weight of bitumen which satisfies all specifications
