Karakterisasi Termal dari Modifikasi Aspal dengan Limbah Plastik Polietilena Grafting Maleat Anhidrat dan Inisiator Dikumil Peroksida

Abstract

Research on the thermal characteristics of asphalt modification with polyethylene (PE) plastic waste grafted with maleic anhydrous and dicumyl peroxide initiator. This research uses 3 stages, the first stage, the used PE is washed and prepared, then the second stage PE is refluxed using xylene solvent at a temperature of 135°C with maleic anhydrous and initiator dicumyl peroxide which produces polyethylene grafting maleic anhydrous (PE-g-MA) and in this stage The final stage is the mixing stage of PE-g-MA with 60170 pen asphalt which is made with 4 types of variations in the weight addition of PE-g-MA of 4%, 6% 8% and 10% in 100 grams of asphalt weight. Modified asphalt is made by mixing pen 60/70 asphalt and PE-gMA in a motorized stirrer at a temperature of J 80°C for 30 minutes which is then characterized by a viscosity test using Brookfield Thermosel Viscosity and a thermal analysis test using Thermogravimetric Analysis (TGA). The asphalt viscosity test results show the optimum value for variations of PE-g-MA modified asphalt with variations in the addition of 4% PE-g-MA. The results of thermal characterization using TGA show that PE-g-MA nwdified asphalt with variations in the addition of 4% PE-g-MA shows decomposition of 1 stage of mass loss, namely at a temperature of 559.32°C with a mass loss of 80.24%.
