<![CDATA[The road has been used in many different loading types, affecting their performance. The increase in traffic of the vehicles is the main factor causing road damage, and including the problems of increasing environmental pollution causing to involves us thinking about improving the pavement characteristic and quality of the road pavement by using polymer modification materials that satisfy both the strength and economic aspects. Thus, this study aims to find the best combination of bitumen and plastic for long-term performance by comparing the stability of conventional and modified bituminous concrete. This study investigates the behavior of bituminous concrete mixed with bottle caps as recycled plastic waste in two processes the wet and dry processes. The various percentage of recycle plastic waste of 2%,4%,6%,8%,10% and 3%,4%,5%,6%,7%,8% were used in dry process and wet process, respectively. Marshall test properties such as stability, flow value, air void, etc., are used to determine the optimum recycling of plastic waste content. The result indicated improvement of the modified binder of the wet process's engineering properties and increases the mechanical properties of the bituminous concrete. The 8% of the recycled plastic content showed the maximum marshall stability of the wet process and optimum value for the dry process. The recommended method for use in toad construction is the dry process. It improves the base bitumen and stability, which resistance to deformation, rutting, and shear stress.]]>
