Aspal beton merupakan suatu jenis perkerasan yang terdiri atas campuran agregat kasar dan agregat halus, bahan pengisi (filler) dan aspal sebagai bahan pengikat. Pada penggunaan Tiram (Crassostrea Gigas) sebagai pengganti agregat halus. Cangkang tiram ini didapat di Desa Tibang, Kecamatan Syiah Kuala. Cangkang tiram yang digunakan lolos saringan No. 4 (4,75 mm) digunakan sebagai substitusi agregat halus. Bahan pengisi (filler) digunakan adalah dari fly ash batu bara di peroleh dari PT. Mifa Bersaudara Kabupaten Aceh Barat. Filler yang digunakan adalah lolos saringan No. 200 (0,075 mm). Penelitian ini bertujuan untuk mengetahui pengaruh substitusi fly ash batu bara variasi 5%, 10%, dan 15% dan mengetahui pengaruh subtitusi cangkang tiram 25%, 50%, 75% dan 100% sebagai agregat halus, serta mengetahui substitusi limbah plastik LDPE (Low Density Polyethylene) botol air mineral dengan persentase 2%, 4% dan 6% sebagai substitusi aspal terhadap karakteristik campuran lapisan aspal beton AC-WC untuk perkerasan jalan sesuai dengan Spesifikasi Umum Bina Marga (2018). Penelitian ini dilaksanakan secara eksperimen di Laboratorium Jalan Raya Universitas Syiah Kuala. Berdasarkan perhitungan yang diperoleh nilai kadar aspal optimum 5,91%, divariasikan menjadi 3 kadar aspal yaitu 5,78%, 5,91% dan 6,04%. Substitusi fly ash terbaik yaitu 5%,substitusi cangkang tiram pada 75% dan substitusi LDPE botol air mineral pada 2%. Berdasarkan hasil perhitungan durabilitas maka dapat disimpulkan kadar aspal 5,91% dengan substitusi fly ash 5% sebagai filler, cangkang tiram 75% sebagai agregat halus dan LDPE botol air mineral 2% memenuhi syarat spesifikasi Umum Bina Marga (2018) yaitu minimal 90% dan nilai Indeks Stabilitas Sisa terbaik yaitu 91,66%.

Asphalt concrete is a type of pavement that consists of a mixture of coarse and fine aggregates, fillers and asphalt as a binder. On the use of oysters (Crassostrea Gigas) as a substitute for fine aggregate. These oyster shells are obtained in Tibang Village, Syiah Kuala District. This oyster shell is obtained in Tibang Village, Syiah Kuala District. The oyster shells used passed the No. 4 sieve (4.75 mm) used as a substitute for fine aggregate. The filler used was coal fly ash obtained from PT Mifa Bersaudara, West Aceh Regency. The filler used was passed through sieve No. 200 (0.075 mm). This study aims to determine the effect of 5%, 10%, and 15% variations of coal fly ash substitution and to determine the effect of 25%, 50%, 75% and 100% oyster shell substitution as fine aggregates, and to determine the substitution of mineral water bottle LDPE (Low Density Polyethylene) plastic waste with a percentage of 2%, 4% and 6% as an asphalt substitution on the characteristics of the AC-WC concrete asphalt layer mixture for road pavement in accordance with Bina Marga General Specifications (2018). This research was conducted experimentally at the Highway Laboratory of Syiah Kuala University. Based on the calculations obtained, the optimum asphalt content value is 5.91%, varied into 3 asphalt levels, namely 5.78%, 5.91% and 6.04%. The best fly ash substitution is 5%, oyster shell substitution at 75% and LDPE mineral water bottle substitution at 2%. Based on the results of the durability calculation, it can be concluded that the 5.91% asphalt content with 5% fly ash substitution as filler, 75% oyster shell as fine aggregate and 2% mineral water bottle LDPE meets the requirements of the Bina Marga General Specifications (2018) which is at least 90% and the best Residual Stability Index value is 91.66%.
