Rutting, stripping and fatigue represent serious distresses which lead to complete failure of the pavement. These distresses could minimize the performance of asphalt pavements. In Iraq, under the influence of repeated vehicle loading, high temperature at summer days and water damage, specific requirements are needed to control the quality of highway materials especially asphalt binder since some of the distresses are related with asphalt binder and can be controlled by modifying asphalt with several modifiers in order to increase the durability of the pavement and to reduce the effect of rutting and moisture damage. The main objective of this research is to study the effects of using hybrid elastomer and plastomer polymers modifiers and aggregate gradation on the asphalt mixture resistance to rutting. In this study, different types and concentration of polymers are used. 1% and 3% of Polyvinyl Chloride (PVC) were added for both control asphalt binder and asphalt modified with 3% Styrene Butadiene Styrene (SBS). To evaluate rutting depth, roller compactor and wheel-track devices test were used in this paper.
