Influence of LDPE Plastic Waste on Asphalt Mixture Soaked in Sea Water

Abstract

Coastal road pavement ability needs to be improved in order to maintain a good asphalt performance. Samples are made to find a perfect formula for a good performance LDPE, LDPE were added into the mixture with proportion as follows 1%, 2%, 3%, 4%, and 5%. LDPE were chosen because the numbers out on consumption of instant food and beverages as well as cleaning agent for daily use. This research is aiming to investigates the influences of adding LDPE materials in of adding LDPE material in the asphalt mixture to Marshall Parameter values. This will help to reduce the waste and create good asphalt mixture. Researchers has made sixty samples soaked in the seawater for 6, 12, 24, and 48 hours, then do the Marshall Test. The results of this research are the asphalt mixture with LDPE waste has an increase in 1-2% content and has a peak in 3% content, for 4-5% content has a decrease for some Marshall Parameter. In substitution level of LDPE test, it has maximum content at 3% in every soaked process. Thus, adding LDPE waste give a good value to the Marshall Parameters at 3% content, especially for asphalt mixture, which is resistant to the seawater.
