Asphalt Modified Plastic Waste to Defend Damage in Asphalt Concrete (Ac-Wc)

Abstract

Plastic bottles (PET) and take-away food containers (PS) waste could be reusable to fix asphalt physical trait that sensitive toward temperature and enhancing the stability of asphalt concrete. Thus it could be used to prevent the damage on rigid pavement such as deformation, corrugation, rutting, and shoving. This research aims to fix asphalt physical trait and to find how much plastic waste percentage (PP+PS) needed so it could replace the asphalt component in Asphalt Concrete (AC-WC). The research is conducted by testing 75 sample with maximum asphalt level of 5.6% and plastic waste percentage ranging from 0%; 2%; 4%; 6%; and 8% compared to asphalt weight. Marshall Test was done in the sample that is soaked in the temperature of 60°C; 70°C; 80°C for 30 minutes and 60°C for 24 hours. Based of Asphalt Pavement Specification (Bina Marga revision 3rd, 2010), hence the percentage of plastic waste that could be used to replace partial asphalt component in Concrete Asphalt (AC-WC) is only 2% of asphalt weight. This percentage is not only fulfilling Marshall characteristic number but also could prevent the further road damage and extremely weatherproof.
