Road infrastructure is a means of transportation that is quite important in developing the economy in a region, so it is necessary to increase the quality and quantity of materials used and to add or modify the material used in the asphalt mixture by using gypsum powder waste and polymer asphalt. This study was aimed to determine the performance of the polymer-modified asphalt mixture using gypsum powder filler on the Asphalt Concrete Wearing Course (AC-WC) layer. The method used in this study was a laboratory experiment with Marshall testing with variations in the content of gypsum powder fillers, namely 0, 1, 2 and 3%. The results showed that the addition of gypsum powder filler could increase the value of the void in the mixture and the void in mineral aggregates, but it can reduce the value void filled with asphalt, stability and flow values. This affected the specific gravity and reduced durability of the asphalt mixture, but it provided the benefit of being able to accelerate the stiffening of the asphalt and make the asphalt mixture more, resulting in resistance to deformation damage.
