Abstract

Kerusakan konstruksi jalan banyak terjadi diakibatkan oleh suhu dan curah hujan yang tinggi sehingga mengakibatkan banyaknya ruas jalan yang rusak. Struktur lapis yang sangat rawan untuk rusak yaitu pada lapis aus (AC-WC). Solusi pencegahan yang dapat dilaksanakan ialah dengan pemanfaatan limbah pasir sisa tambang emas sebagai bahan baku pengganti agregat halus pada campuran aspal beton AC-WC.
Tujuan dari penelitian ini yaitu untuk (1) Mendeskripsikan karakteristik bahan penyusun campuran Asphalt Concrete Wearing Course (AC-WC); (2) Mendeskripsikan nilai Kadar Aspal Optimum (KAO) pada campuran Asphalt Concrete Wearing Course (AC-WC); (3) Mendeskripsikan pengaruh penambahan pasir sisa limbah tambang emas pada campuran Asphalt Concrete Wearing Course (AC-WC) ditinjau dari parameter Marshall. Metode penelitian yang digunakan meliputi: (1) studi literature; (2) pemilihan dan pengujian bahan; (3) pembuatan benda uji dengan variasi kadar aspal 5,5%, 6%, 6,5%, 7%, 7,5% sebagai kontrol dan untuk mencari KAO; (4) pembuatan benda uji modifikasi dengan kadar aspal KAO dan variasi agregat halus berupa limbah pasir sisa tambang emas 0%, 25%, 50%, 75%; (5) pengujian dengan Marshall sesuai dengan spesifikasi pada Bina Marga 2018 Revisi 2.
Hasil penelitian ini diperoleh (1) karakteristik keseluruhan dari agregat kasar, agregat halus, dan aspal yang digunakan sebagai campuran aspal AC-WC memenuhi standar yang telah ditetapkan sedangkan campuran terbaik diperoleh kadar aspal 6,25% dengan kadar agregat 75%. (2) penggunaan pasir limbah tambang emas sebagai pengganti agregat halus pada campuran aspal AC-WC ditinjau dari parameter Marshall mencakup: (a) nilai stabilitas tertinggi diperoleh pada kadar aspal 6,25% dengan variasi kadar agregat 75% sebesar1202,87 kg; (b) menurun dengan bertambahnya kadar agregat namun meningkat kembali pada kadar agregat 75% sebesar 2,46 mm; (c) Nilai Marshall Quotient (MQ) meningkat seiring bertambahnya kadar agregat dan nilai tertinggi terdapat pada kadar agregat 75% sebesar 498,33 kg/mm; (d) Nilai VMA dan VFA memiliki nilai yang berdekatan dan mengalami naik turun pada setiap kadar agregatnya, dari keseluruhan kadar agregat memenuhi persyaratan batas minimum dalam Spesifikasi Bina Marga 2018 Rev.2.

Many road construction damages occur due to high temperatures and rainfall, resulting in many damaged road sections. Layer structures that are very prone to damage are in the wear layer (AC-WC). The preventive solution that can be implemented is to use gold mine sand waste as raw material to replace fine aggregate in the AC-WC concrete asphalt mixture.
The purpose of this study is to (1) Describe the characteristics of the materials that make up the Asphalt Concrete Wearing Course (AC-WC) mixture; (2) Describe the value of the Optimum Asphalt Content (KAO) in the Asphalt Concrete Wearing Course (AC-WC) mixture; (3) To describe the effect of adding sand from gold mine waste to the Asphalt Concrete Wearing Course (AC-WC) mixture from Marshall parameters. The research methods used include: (1) literature studies; (2) material selection and testing; (3) the manufacture of test specimens with asphalt content variations of 5.5%, 6%, 6.5%, 7%, 7.5% as a control and to search for KAO; (4) the manufacture of modified test pieces with KAO asphalt content and fine aggregate variations in the form of 0%, 25%, 50%, 75% gold mine residual sand waste; (5) testing with Marshall in accordance with the specifications in Bina Marga 2018 Revision 2.
The results of this study were obtained (1) the overall characteristics of coarse aggregate, fine aggregate, and asphalt used as an AC-WC asphalt mixture met the set standards while the best mixture was obtained with an asphalt content of 6.25% with an aggregate content of 75%. (2) the use of gold mine waste sand as a substitute for fine aggregate in the AC-WC asphalt mixture reviewed from Marshall's parameters includes: (a) the highest stability value was obtained at an asphalt content of 6.25% with a variation in aggregate content of 75% amounting to 1202.87 kg; (b) decreased with the increase in aggregate content but increased again at an aggregate level of 75% of 2.46 mm; (c) The Marshall Quotient (MQ) value increases with the increase in aggregate content and the highest value is found at an aggregate rate of 75% of 498.33 kg/mm; (d) VMA and VFA values have adjacent values and fluctuate in each aggregate level, from the entire aggregate level meets the minimum limit requirements in the 2018 Bina Marga Specification Rev.2.
