Nowadays plastics are used everyday in every aspect of our lives which is a great problem as they are non-biodegradable. They are disposed either by landfilling or incineration of the waste materials which causes environmental pollution and health problems. This paper studies the influence of reusing waste plastic (WP) in hot mix asphalt (HMA). Three different methods were used to add waste plastics to HMA with five different percentages of waste plastic at each method. To determine the best method of adding WP to HMA and the optimum WP content Marshall specimens were prepared and tested to measure their stability, flow, stiffness, indirect tensile strength, and loss of stability. It was concluded that the third method was the best method for adding WP, the optimum WP content differs for each type of WP, using WP improved the mechanical properties of the HMA, and its durability.
