Abstract

Sustainable development encourages the use of waste as an alternative material in infrastructure, including on road pavement. This study evaluated the performance of Laston Coated Wear (AC-WC) asphalt mixture with the substitution of glass waste as fine aggregates in variations in 0%, 10%, 20%, and 30% levels. Material characteristics testing as well as Marshall tests and residual stability were carried out referring to the General Specification of Highways Division 6 of 2018 Revision 2. The results show that the glass waste meets the technical specifications as a fine aggregate. Blends with 10% glass content produce the highest Marshall stability value of 93.4% and the best overall performance. The Optimum Asphalt (KAO) content has increased as the glass content has increased, but it remains below the normal mix KAO. Mixing with glass also shows good water resistance. Therefore, a 10% glass waste substitution is recommended as an alternative to fine aggregates in AC-WC mixtures to support environmentally friendly road infrastructure.

Abstract

Studi ini bertujuan untuk mengevaluasi efektivitas kapur sebagai bahan pengisi (filler) alternatif dalam campuran aspal tipe Asphalt Concrete Wearing Course (AC-WC) dengan mempertimbangkan performa mekanis dan daya tahan campuran. Penelitian dilakukan dengan variasi kadar kapur sebesar 0%, 25%, 50%, dan 75% sebagai pengganti sebagian filler konvensional. Metode pengujian meliputi analisis sifat fisik agregat dan kapur, uji Marshall untuk menentukan parameter stabilitas, kelelehan, flow, void in mix (VIM), serta uji stabilitas sisa untuk mengevaluasi ketahanan campuran terhadap pengaruh beban berulang dan kelembapan. Hasil penelitian menunjukkan bahwa penambahan kapur mampu meningkatkan stabilitas campuran, dengan performa terbaik pada kadar 50%, yang mencatat nilai stabilitas sisa sebesar 94,5%, melebihi campuran tanpa kapur. Selain itu, kadar aspal optimum (optimum asphalt content) cenderung meningkat seiring dengan bertambahnya proporsi kapur, menunjukkan bahwa kapur dapat meningkatkan ikatan antara aspal dan agregat. Namun, pada kadar 75%, terjadi penurunan pada beberapa parameter teknis seperti kelelehan dan VIM, sehingga tidak direkomendasikan untuk penggunaan maksimal. Berdasarkan hasil ini, penggunaan kapur sebesar 50% dianggap paling optimal untuk meningkatkan mutu, efisiensi, serta kinerja lapisan permukaan jalan AC-WC.

Abstract

The limited learning facilities at MTs Baitul Mubarok, including the absence of classroom ceilings, damaged doors, and unfit desks, chairs, and whiteboards, have hindered comfort and safety in the learning process. The Community Service Program (PKM) of the Civil Engineering Department at Politeknik Negeri Pontianak was carried out to provide and refurbish these facilities while offering practical learning experiences for students. The method included situation analysis, planning, material preparation, product fabrication in the workshop, and delivery to the partner. The program produced 36 desks, 76 chairs, 3 whiteboards, and 3 sets of classroom doors, all meeting the standards of Permendiknas No. 24/2007. The activity improved the quality of learning facilities, enhanced student comfort, and strengthened students' technical skills and social awareness, although ceiling repairs could not be completed due to budget limitations.
