Abstract

PVC waste management is often a problem, and this happens because PVC is a material that
cannot be decomposed naturally. Therefore, innovation is needed to dispose of large amounts of PVC
waste. One way is to turn the waste into an additive to the asphalt mixture. Adding PVC into asphalt can
improve its performance, namely by increasing its softening point value so that asphalt can resist weather
changes. This study aims to: (1) Describe the characteristics of the AC-WC mixture without adding PVC
in terms of Marshall parameters. (2) describe the characteristics of the AC-WC mixture with the addition
of PVC in terms of Marshall parameters. (3) Determine the optimum level of PVC added to the AC-WC
pavement mixture. (4) Determine the value of residual strength index (IKS) in the AC-WC mixture with
the 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, the
IKS test specimens were made with optimum bitumen and PVC content, and the Marshall test was carried
out. The results of this study showed: (1) The characteristics of the AC-WC mixture without the addition
of 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 mixture
with the addition of PVC is that the stability value increases by adding up to 4% PVC content but
decreases at 6% to 10%. Flow, VIM, and VMA values
increase as the PVC content increases, but
VFA values
tend to decrease. (3) The optimum level of PVC addition is found at 4.2% by weight of
asphalt. (4) The mixture with the addition of 4.2% PVC has a higher IKS value than the mixture without
the addition of PVC. This indicates that the AC-WC mixture with the addition of PVC can have better
temperature and water resistance compared to the AC-WC mixture without adding additives.
