The Effect of PET Plastic Addition (Polyethylene Terephthalate) and Carbide Waste Filler for Asphalt Concrete-Binder Course (AC-BC) on Marshall Characteristics

Abstract

To improve the quality of infrastructure that is durable and solid, innovation needed to make sure the high quality ofroads. This study aimed at knowing the effect of PET addition in the percentage of 0%, 1%, 1.5%, and 2% for asphalt concrete-binder course on Marshall characteristics, and revealing whether the results of Marshall testing with added PET material and carbide waste filler has fulfilled the general specification of Directorate General of Highway 2010. This study used PET plastic addition with variations of 0%, 1%, 1.5% and 2%. Each variation of PET content was made on 3 samples for objects testing to obtain values of density, VIM, VMA, VFA, stability, flow, and MQ. The results of this study indicated that the addition of PET plastic content and carbide waste filler affects the value of the asphalt characteristic of Marshall. The most effective addition was at 1% level with a density of 2.23 gr/cc, VIM value of 4.82%, VMA value of 14.58%, VFA value of 67.18%, flow value of 3.30 mm, stability value of 3060.42 kg and MQ value of 936.79 kg/mm. Overall, the addition of PET plastic and carbide waste filler to the characteristics of the marshall.
