PVC waste management is often a problem, and this happens because PVC is a material thatcannot be decomposed naturally. Therefore, innovation is needed to dispose of large amounts of PVCwaste. One way is to turn the waste into an additive to the asphalt mixture. Adding PVC into asphalt canimprove its performance, namely by increasing its softening point value so that asphalt can resist weatherchanges. This study aims to: (1) Describe the characteristics of the AC-WC mixture without adding PVCin terms of Marshall parameters. (2) describe the characteristics of the AC-WC mixture with the additionof PVC in terms of Marshall parameters. (3) Determine the optimum level of PVC added to the AC-WCpavement mixture. (4) Determine the value of residual strength index (IKS) in the AC-WC mixture withthe addition of PVC. PVC material is mixed into the asphalt with variations in the addition of PVC of 0%,2%, 4%, 6%, 8%, and 10% by weight of the asphalt, and then the Marshall test is carried out. Next, theIKS test specimens were made with optimum bitumen and PVC content, and the Marshall test was carriedout. The results of this study showed: (1) The characteristics of the AC-WC mixture without the additionof PVC were that the stability value increased up to 6% and decreased at 6.5% and 7% asphalt content.Meanwhile, the value of flow and VFA has increased. The VIM value decreased, as did the VMA value,which decreased at 5.5% and increased at the next level. (2) The characteristic of the AC-WC mixturewith the addition of PVC is that the stability value increases by adding up to 4% PVC content butdecreases at 6% to 10%. Flow, VIM, and VMA valuesincrease as the PVC content increases, butVFA valuestend to decrease. (3) The optimum level of PVC addition is found at 4.2% by weight ofasphalt. (4) The mixture with the addition of 4.2% PVC has a higher IKS value than the mixture withoutthe addition of PVC. This indicates that the AC-WC mixture with the addition of PVC can have bettertemperature and water resistance compared to the AC-WC mixture without adding additives.
