    ABSTRAK
    Asphalt Concrete–Binder Course (AC–BC) adalah lapisan perkerasan jalan yang
    berada di bawah lapisan aus (wearing course) dan di atas lapisan pondasi (base
    course) atau di sebut sebagai lapis antara. Penggunaan batu laterit sebagai subtutusi
    agregat kasar dan penambahan karung plastik sebagai bahan tambah campuran AC-
    BC dapat mempengaruhi sifat-sifat pada campuran aspal beton, khususnya
    kekerasan, kepekaan terhadap temperatur dan pengelupasan. Penelitian ini
    bertujuan mengetahui penggunaan batu laterit sebagai substitusi agregat kasar
    dengan bahan tambah karung plastik pada campuran AC-BC terhadap karakteristik
    marshall dan kepadatan refusal. Benda uji marshall dibuat dengan 50% batu laterit
    sebagai substitusi agregat kasar dan penambahan karung plastik dengan variasi 4%,
    4.5%, 5%, 5.5% dan 6% terhadap berat aspal di campur dengan metode dry
    process. Pengujian durabilitas aspal pada perendaman 24 jam serta menguji
    Percentage Refusal Density (PRD) pada campuran AC-BC. Berdasarkan hasil
    pengujian didapatkan kadar aspal optimum sebesar 5.5% dengan nilai stabilitas =
    1392.62 kg dan didapatkan kadar plastik optimum 5% dengan nilai stabilitas =
    1527.51 kg. Nilai stabilitas marshall sisa didapatkan sebesar 97.94%, untuk metode
    PRD didapatkan nilai Desnsity = 2.36 gr/cc. Penggunaan batu laterit sebagai
    substitusi berdampak terhadap pemanfaatan material lokal yang tersedia di
    Kalimantan Timur dan pemanfaatan limbah karung plastik sangat berdampak
    terhadap pengolahan limbah plastik yang sukar diurai secara alami.

    ABSTRACT
    Asphalt Concrete-Binder Course (AC-BC) is a layer of road pavement that is under
    the wearing course and above the base course or referred to as the intermediate
    layer. The use of laterite stone as a substitute for coarse aggregate and the addition
    of plastic sacks as an added material to the AC-BC mixture can affect the properties
    of asphalt concrete mixtures, especially hardness, sensitivity to temperature and
    peeling. This study aims to determine the use of laterite stone as a substitute for
    coarse aggregate with plastic sack added material in the AC-BC mixture against
    marshall characteristics and refusal density.The marshall test specimen is made
    with 50% laterite stone as a substitute for coarse aggregate and the addition of
    plastic sacks with variations of 4%, 4.5%, 5%, 5.5% and 6% to the weight of asphalt
    mixed by dry process method. Testing the durability of asphalt at 24-hour
    immersion and testing the Percentage Refusal Density (PRD) in the AC-BC mixture.
    Based on the test results, the optimum asphalt content was 5.5% with a stability
    value = 1392.62 kg and an optimum plastic content of 5% was obtained with a
    stability value = 1527.51 kg. The residual marshall stability value was obtained
    at 97.94%, for the PRD method the value of Desnsity = 2.36 gr/cc was obtained.
    The use of laterite stone as a substitute has an impact on the use of local materials
    available in East Kalimantan and the use of plastic sack waste greatly impacts the
    processing of plastic waste that is difficult to decompose naturally.
