ANALISIS PEMANFAATAN PLASTIK POLYSTYRENE (PS) SEBAGAI BAHAN TAMBAHAN ASPAL AC WC DAN AC BC DENGAN METODE MARSHALL

Polystyrene istype of plastic waste thatdifficult to decompose naturally and becomes microplastic which pollutes the environment. Therefore, it is necessary to utilize the plastic waste in a mixture of road pavement.This study aims to determine the effect of add ing polystyrene to AC-WC and AC-BC on the marshall test based on Spesifikasi Umum Bina Marga 2018.. The results shoed that the AC-WC with addition of 4% and 5% polystyrene contenthasstability, VMA, VIM, VFA, flow, and marshall quotient that met the specifications. Meanwhile, theAC-BC with addition of 4% polystyrenecontentdoes not meet the specifications except for VIM and the addition of 5% polystyrenecontentdoes not meet the specifications at all. Utilizat ion of polystyrenein the AC-WC mixture can be recommended as an addit ive in the flexible pavement, while AC-BC is not recommended because it cannot improve the quality of the overall marshall characteristics.
