Increasing the quality of hot asphalt mixtures is continuously carried out with various kinds of experiments, one of which is by mixing additives in the form of polymers. LDPE (Low Density Polyethylene) and HDPE (High Density Polyethylene) are polyethylene chain structures that can be found in daily life, such as the form of plastic food wrappers, plastic bags and shopping bags. This study aims to compare the effect of using LDPE and HDPE plastic waste without the use of plastic waste on the characteristics of the hot asphalt mixture Marshall Asphalt Concrete Wearing Course (AC-WC). After obtaining the optimum asphalt content at 5.6%, the optimum plastic content for LDPE is 2.1% and HDPE is 2.4%. The results of the Marshall characteristic test showed that the stability value of the AC-WC hot asphalt mixture with the addition of HDPE plastic waste was higher, that was 1216 kg, compared to the addition of LDPE plastic which was 1130 kg and without the addition of 1211 kg plastic. The value of flow in the addition of LDPE plastic had the highest value, 3.53 mm compared to the addition of HDPE plastic, 3.27 mm and without the addition of plastic which had the lowest value, 3.20 mm. From the results of residual stability testing with IKS (Residual Strength Index), the addition of LDPE plastic
