Abstract

Repetitive and excessive load pressure by vehicles is one of the damages that occurs on road pavement deformation due to the pavement layer losing its strength, causing the road layer to subside and cracks to occur. Marble waste is the remaining waste acquired from the processing of the marbles. Environmental pollution is caused by the marble processing process. The marble waste produced is increasing gradually over time, therefore, it is needed to utilize that marble waste. The marble waste is expected to improve the quality and performance of the mixture in resisting deformation in the AC-WC mixture and has good mixture characteristics. This research aims to examine the cause of using marble waste on the characteristics and deformation of the mixture. The test in this research applies the marshall test and wheel tracking tool. The result showed that the characteristics of the mixture and KLMO, total deformation, deformation rate, and dynamic stability using KAO 6% and the Optimum Marble Waste Content (KLMO) obtained was 25%. The highest stability and Marshall Quatient were 1024.89 kg and 345.65 kg/mm at 25% marble waste variation. The lowest flow value in the mixture with 25% marble waste variation was 2.97 mm. The 25% variation has good mixture characteristics and durability. The smallest total deformation was 0.903 mm at 25% marble waste variation, dynamic stability 2864 passes/mm, and deformation rate 0.0147 mm/minute.

Abstract

Pesatnya pertumbuhan penduduk menyebabkan semakin maraknya terjadi kerusakan dan keretakan pada konstruksi perkerasan jalan. Retakan terjadi karena adanya beban tekan berulang yang menimbulkan beban vertikal, sehingga terjadi gaya tarik para lapisan bawah yang mengakibatkan retakan yang akan merambat ke atas. Pemanfaatan material lokal menjadi alternatif yang dapat mengurangi biaya angkutan, memudahkan pekerjaan meninjau kualitas dan ekonomi material. Indonesia merupakan negara kepulauan terbesar didunia dan memiliki ketersediaan pasir pantai yang cukup banyak. Tujuan penelitian ini adalah untuk mengetahui karakteristik pada cmpuran beton aspal menggunakan pasir pantai serta kekuatan tarik dan modulus resilien. Variasi pasir pantai adalah 0%, 5%, 10%, 15%, 20%, dan 25%. Aspal rencana yang digunakan adalah 6%, 6,5%, 7%, 7,5%, dan 8%. Pengujian pertama menggunakan alat Marshall Test guna mencari kadar aspal optimum dari tiap variasi persentase pasir pantai. Pengujian kedua menggunakan alat Indirect Tensile Strenght (ITS) berdasarkan Kadar Aspal Optimum dari variasi pasir pantai. Karakteristik campuran menggunakan pasir pantai dapat digunakan pada persentase tertentu dimana nilai hasil uji Marshall memenuhi spesifikasi. Berdasarkan hasil tersebut nilai kuat tarik tertinggi variasi 5% adalah 69283,79 KPa dan nilai modulus resilien tertinggi variasi 25% adalah 5358,49 KPa.
