Penelitian ini mengkaji pemanfaatan limbah plastik elektronik berbasis akrilonitril butadiena stirena (abs) sebagai material substitusi pada campuran asphalt concrete - wearing course (ac-wc). latar belakang penelitian didasari oleh meningkatnya jumlah limbah elektronik serta kebutuhan inovasi material perkerasan yang lebih berkelanjutan. tujuan penelitian adalah menganalisis pengaruh variasi substitusi e-waste sebesar 4%, 6%, 8%, dan 10% terhadap karakteristik marshall pada tiga kadar aspal optimum (5,03%; 5,37%; dan 5,71%), serta mengevaluasi ketahanan campuran melalui uji durabilitas. hasil penelitian menunjukkan bahwa kombinasi kadar aspal 5,37% dengan substitusi e-waste 6% memberikan kinerja terbaik dengan nilai stabilitas tertinggi dan seluruh parameter marshall memenuhi spesifikasi umum bina marga 2018 revisi 2. penambahan e- waste dalam proporsi optimum mampu meningkatkan stabilitas akibat kontribusi kekakuan material abs terhadap struktur campuran. namun, peningkatan persentase yang berlebihan cenderung menurunkan stabilitas karena sifat abs yang tidak menyerap aspal dan memiliki permukaan relatif halus, sehingga efektivitas ikatan antar material berkurang. hasil uji anova menunjukkan bahwa pengaruh signifikan variasi e-waste terutama terjadi pada parameter stabilitas dan marshall quotient pada kadar aspal tertentu. pengujian durabilitas menunjukkan adanya penurunan stabilitas setelah perendaman 24 jam, namun nilai durabilitas masih memenuhi kriteria aashto. kata kunci: ac-wc, e-waste, abs, marshall, durabilitas, anova.

This study investigates the utilization of electronic plastic waste based on Acrylonitrile Butadiene Styrene (ABS) as a substitute material in Asphalt Concrete - Wearing Course (AC-WC) mixtures. The research is motivated by the increasing volume of electronic waste and the need for more sustainable pavement material innovations. The objective of this study is to analyze the effect of E-waste substitution at 4%, 6%, 8%, and 10% on the Marshall characteristics at three optimum asphalt contents (5.03%; 5.37%; and 5.71%), as well as to evaluate the durability performance of the mixture through durability testing. The results indicate that the combination of 5.37% asphalt content with 6% E-waste substitution provides the best performance, yielding the highest stability value while satisfying all Marshall parameters specified in the 2018 General Specifications of Bina Marga (Revision 2). The incorporation of E-waste at an optimum proportion enhances stability due to the stiffness contribution of ABS material to the mixture structure. However, excessive substitution tends to reduce stability because ABS does not absorb asphalt and has a relatively smooth surface texture, thereby reducing the effectiveness of the bonding between materials. The ANOVA test results reveal that the variation in E-waste content has a statistically significant effect, particularly on the stability and Marshall Quotient parameters at certain asphalt contents. Durability testing shows a decrease in stability after 24- hour immersion; nevertheless, the retained stability value still satisfies AASHTO requirements.
