The use of plastic waste as an asphalt-concrete mixture in road construction with flexible pavements can overcome chemical waste. Many studies have been carried out on plastic waste used as an aggregate material for road construction with flexible pavements, including this research. This paper discusses polyethylene terephthalate (PET) and polypropylene (PP) plastic waste as an additive for the modification of the asphalt-concrete mixture. The sample was made using a cylindrical mold with 10 cm height and a diameter of 10 cm. Asphalt Buton type Retona Blend 55, fine and coarse aggregates and fillers are mixed at a mixing temperature of 160 ± 0.5 ° C, with a total mixture weight of 1,600 grams. The compressive strength test was carried out on the asphalt-concrete combination using Modified Buton Asphalt (MBA) as a binder with PET and PP Processed and has not been processed based on Indonesian test standards (SNI 03-6758-2002). Comparison of 3% asphalt binder mixture to total aggregate and the ratio of adding PET and PP (100: 0%, 0: 100%, and 50: 50%). The results showed that the compressive strength of the AC-WC treatment was higher than without treatment. Also, PET and PP can mix with an MBA as a better binder and result in higher strength. The pavement analysis's important elasticity parameter is the Poisson ratio, where the test results show that the modulus of elasticity and the Poisson ratio follow the standard, namely 80% of the peak load.
