Studi Eksprimental Dengan Metode Marshall Pemanfaatan Plastik Polystyrene Sebagai Bahan Aspal AC-BC
AI summary Read the abstract
Researchers experimentally investigated the addition of polystyrene plastic waste at 4% and 5% content to AC-BC asphalt mixtures using the Marshall method, evaluating compliance with 2018 Indonesian Bina Marga specifications. The study found that only the 4% polystyrene addition met the VIM specification requirement, demonstrating limited viability for polystyrene as an asphalt modifier at higher concentrations.
Polystyrene plastic waste is difficult to decompose naturally and becomes microplastics which pollute the environment. Therefore, plastic waste is utilized in road pavement mixtures. This research aims to find out whether the addition of Polystyrene to AC-BC asphalt with levels of 4% and 5% can improve the quality of asphalt based on the 2018 General Bina Marga specifications. This research was carried out in a laboratory and analyzed using the Marshall method. AC-BC asphalt test results with polystyrene content of 4% and 5%, show that only the VIM value at 4% plastic content with a value of 3.88% meets and 5% plastic content with a value of 2.58% does not meet the range of 3%-5%. , then apart from the VIM value of AC-BC asphalt it meets the specifications.

Performance Evaluation of Marshall Mixed Asphalt Concrete-Binder Course (AC-BC) Using Modified LDPE Waste Asphalt with the Wet Method
AI summary Read the abstract
This study tested adding Low-Density Polyethylene (LDPE) plastic waste to road asphalt binder layers and found it improved pavement stability, with the best results at a 7% LDPE addition rate. While focused on road engineering rather than microplastic pollution, it is relevant because plastics incorporated into asphalt can fragment and shed tire-road microplastic particles into the environment over time.
