Study on Marshall Stability of Asphalt Concrete Mixture Due to the Addition of Polyethylene Terephthalate (PET)
Rapid population growth is directly proportional to the increase in the consumption of polymers or plastics. It is very difficult to decompose in the soil, efforts to use it as an additional material for road construction are important. The addition of polymer can increase the stiffness of the asphalt so that it will improve the quality of the pavement against rutting. [4][5]. The purpose of this study is to determine the effect of adding plastic waste Poly Ethylene Terephalate (PET) mineral plastic bottles to stability of Asphalt Concrete – Wearing Course (AC-WC) mixture using 60/70 penetration asphalt, and to analyze the microscopic structure of the results of Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS) tests. From the Marshall test, it is known that the stability of the mixture in each variation of the addition of PET meets the required specifications of a minimum of 1000 kg. The highest average stability of 1855.7 kg in all variations of asphalt content was recorded of PET 1.25% of the asphalt weight, which increase the ability of the asphalt mixture of 39% to carry loads. Meanwhile, the smallest stability increase of 3% occurred in the addition of 0.5% PET into asphalt. Through the SEM test, it was seen that there were so many lumps with a larger structure size as a result of the reaction between the asphalt mixture and PET. This agglomeration becomes a structure that is stronger in carrying Marshall loads as detected at a higher stability value of the mixture.
