Abstract

Abstrak   Sampah plastik mencemari lingkungan menjadi penyumbang terbesar di indonesia, pendauran ulang dapat dilakukan dengan menjadikan substitusi aspal. Lapisan AC-WC (Asphalt Concrete-Wearing Course) merupakan lapisan perkerasan yang terletak paling atas berfungsi sebagai lapisan aus, terdiri dari agregat kasar, halus, filler dan aspal. Penggunaan plastik HDPE (High Density Polyethylene) dan LDPE (Low Density Polyethylene) sebagai pengganti aspal sebagian dalam campuran lapisan AC-WC guna meningkatkan nilai stabilitas yang lebih besar dari aspal konvensional dan berfungsi sebagai bahan pengikat antara agregat yang bersifat termoplastis. Tujuan penelitian untuk mengetahui variasi pemanfaatan plastik HDPE dan plastik LDPE yang dapat memenuhi nilai parameter marshall. Benda uji yang digunakan 15 buah untuk KAO dan 3 benda uji untuk masing-masing variasi 5%, 6% dan 7%. Pengujian adalah pengujian marshall. KAO pada kadar aspal sebesar 6%. Hasil penelitian menunjukkan nilai parameter marshall memenuhi spesifikasi. Dapat disimpulkan bahwa dengan substitusi sebagian aspal dengan plastik HDPE dan plastik LDPE variasi 5%, 6% dan 7% memenuhi Spesifikasi Umum Bina Marga 2018 Revisi 2.   Kata kunci: Laston AC-WC, Parameter Marshall, Plastik HDPE, Plastik LDPE   Abstrack   Plastic waste is a major environmental pollutant and represents one of the largest sources of pollution in Indonesia. One potential recycling approach is its utilization as a partial substitute for asphalt. The AC-WC (Asphalt Concrete–Wearing Course) layer is the uppermost pavement layer, functioning as a wearing course, and consists of coarse aggregate, fine aggregate, filler, and asphalt binder. The use of HDPE (High Density Polyethylene) and LDPE (Low Density Polyethylene) plastics as partial replacements for asphalt in AC-WC mixtures aims to improve stability values compared to conventional asphalt and to act as a thermoplastic binder between aggregates. This study aims to evaluate variations in the use of HDPE and LDPE plastics that satisfy Marshall parameter requirements. A total of 15 specimens were prepared to determine the Optimum Asphalt Content (OAC), while 3 specimens were tested for each plastic variation of 5%, 6%, and 7%. Marshall testing was conducted, and the OAC was found to be 6%. The results indicate that all Marshall parameters meet the specified requirements. It can be concluded that partial substitution of asphalt with HDPE and LDPE plastics at 5%, 6%, and 7% variations complies with the 2018 Bina Marga General Specifications (Revision 2).   Keywords: Laston AC-WC, Marshall Parameters, HDPE Plastic, LDPE Plastic
