Abstract
Using plastic waste in asphalt mixtures may increase the service life of the asphalt pavement surface while also reducing waste. The purpose of this study is to see how Low-Density Polyethylene (LDPE) asphalt additives affect the Marshall properties of asphalt concrete wearing course (AC-WC). 42 AC-WC pavement samples were created using the Bina Marga 2018 specification and the Indonesian National Standard for Asphalt Testing. Using the wet process, 5-8% LDPE with 0.5% intervals of the optimum asphalt content were added to the samples. Marshall tests were performed to determine the optimum asphalt and LDPE content. The optimal asphalt content was 6.5%, and the optimal plastic content was 7.5%. The results show that adding 7.5% LDPE can improve Marshall stability by two times, from 977.18 kg to 2103.44 kg, and reduce asphalt content consumption by up to 7.05% compared to the mixture without the addition of LDPE.
