Abstract

Abstract Rutting is a type of damage that occurs in the form of grooves on the road pavement surface caused by traffic loads, material quality, and asphalt mix design. This study aims to determine the potential for rutting in a Split Mastic Asphalt-Fine mix using two types of aggregate, namely aggregate-1 and aggregate-2. Permanent deformation test was conducted using a Hamburg Wheel Tracking Device under dry conditions at 60°C and 10,000 passes. This study shows that aggregate characteristics influence the potential for rutting. Test results indicate that the SMA-Fine asphalt mix using aggregate-1 has better permanent deformation resistance than the SMA-Fine asphalt mix using aggregate-2. Keywords: rutting damage; asphalt mix; permanent deformation; aggregate characteristics Abstrak Kerusakan Rutting merupakan suatu kerusakan yang berbentuk alur pada permukaan perkerasan jalan yang disebabkan oleh beban lalu lintas, kualitas material, dan rancangan campuran beraspal. Studi ini bertujuan untuk menentukan potensi terjadinya rutting pada campuran Split Mastic Asphalt-Halus, yang menggunakan 2 jenis agregat, yaitu agregat-1 dan agregat-2. Pengujian deformasi permanen dilakukan dengan alat Hamburg Wheel Tracking Device, dengan kondisi kering pada temperatur 60°C dan 10.000 lintasan. Studi ini menunjukkan bahwa karakteristik agregat memengaruhi potensi terjadinya kerusakan rutting. Hasil pengujian menunjukkan campuran beraspal SMA-Halus yang menggunakan agregat-1 memiliki ketahanan deformasi permanen yang lebih baik dibandingkan dengan campuran beraspal SMA-Halus yang menggunakan agregat-2. Kata-kata kunci: kerusakan rutting; campuran beraspal; deformasi permanen; karakteristik agregat

Abstract

A road is usually defined as an infrastructure connecting a zone to other zones. As service and safety are essential for vehicle users, any conditions related to the pavement, including surface texture, are considered. The importance of this matter is that many researchers or practitioners are concerned with the quality of asphalt mixtures, whether structural or functional, which affect the safety and security of road users, mainly related to the texture of the pavement surface. This research aims to determine the texture depth (MTD, Mean Texture Depth). The research method used is the circle sand method, which is tested using the Sand Patch tool. The asphalt mixture type uses AC-WC with a composition of 39% coarse aggregate, 54.5% fine aggregate, and 6.5% filler. Optimum Asphalt Content of 6.28% and Density of 2.28 were obtained, and texture depth of 0.549 mm was more significant than 0.45 mm (Bina Marga 2010 revision 3). The conclusion is based on the design composition of the aggregate mix in the AC-WC asphalt mixture, which has a safe texture.
