The need for Asphalt materials that yield a high stability value to prevent road damage and improve driving safety and comfort will continue to increase. However, the availability of asphalt is dwindling because it is a non-renewable material. This study aims to determine the effect of adding PET plastic waste and latex rubber as a partial replacement for asphalt in the AC-WC mixture. This research was carried out by testing asphalt penetration 60/70 with 3 types of addition of partial asphalt replacement materials and making 63 samples, of which 45 samples with 3 types of mixtures and 5 variations of asphalt content for the Marshall test, as well as 18 samples for the Marshall Immersion test. The test method used is based on the General Specifications for Highways 2010 Revision 3. This modified asphalt mixture research summarizes that the mixture with the addition of 3% PET plastic waste obtained a VMA value of 17.90%, a VFA of 75.16%, a VIM of 4.44%, a stability of 2901 kg, and a flow of 3.1 mm, at mixture with the addition of 3% latex rubber obtained VMA 17.93%, VFA 80.76%, VIM 3.45%, stability 2335 kg, and flow 3.2 mm, in a mixture with the addition of latex rubber 6% obtained VMA 18.07 %, VFA 79.53%, VIM 3.70%, stability 2176 kg, and flow 3.1 mm. As well as the results of the Marshall Immersion test on asphalt mixtures with the addition of PET plastic waste and latex rubber as a partial replacement for asphalt, with the addition of 3% PET plastic waste, 3% latex rubber, and 6% latex rubber of the total weight of the asphalt mixture, the residual Marshall stability value has been obtained. each of 81.2%, 94.5% and 90.7%. So, the addition of latex rubber as a partial replacement for asphalt can make the mixture more resistant and stronger, reducing damage from water and weather.
