ABSTRAK
Â
Analisis kondisi fungsional perkerasan jalan yang dilakukan pada pengelolaan perkerasan jalan lentur untuk jalan tol di Indonesia ditentukan berdasarkan Nilai Kondisi Jalan. Penilaian tersebut merupakan penggabungan penilaian kondisi perkerasan berdasarkan ketidakrataan permukaan perkerasan, alur, dan kerusakan utama permukaan perkerasan. Pada pengelolaan pemeliharaan perkerasan, penentuan umur sisa perkerasan sangat penting untuk digunakan sebagai penentuan program penanganan pemeliharan jalan. Telah dilakukan penelitian tentang hal ini berdasarkan metode analisis statistik yang menghasilkan hubungan antara ketidakrataan permukaan perkerasan dengan umur sisa pelayanan perkerasan. Analisis menggunakan data time serries untuk jalan tol Surabaya-Gempol di Jawa Timur tahun 2007, 2010, 2012, dan 2014. Hubungan yang diperoleh bertendensi eksponensial dan dapat digunakan untuk memprediksiumur sisapelayanan perkerasan. Makalah ini bermaksud menbahas kajian tentang hubungan empirik antara ketidakrataan permukaan perkerasan dengan umur sisa pelayanan jalan dalam rangka mencari model yang dapat dipakai untuk memprediksi umur sisa pelayanan perkerasan.

ABSTRACT
Â
Functional pavement condition analysis conducted on the management of flexible pavement on toll roads in Indonesia is determined based on the Road Condition Value. It is a combination of pavement condition assessment based on roughness, rutting, and major damage of pavement surface. On the pavement maintenance management, the determination of remaining service life is very important to be used as a determination of road maintenance management program. Research hasbeen carried out based on statistical analysiswhich resulting in relationships between roughness of pavement surface andremaining service life. The analysis used time series data of 2007, 2010, 2012, and 2014 for Surabaya – Gempol toll road. Obtained relationships tended exponential and could be used for remaining service life prediction. This paper aims to describe the analysis of empirical relationship between roughness of pavement surface and remaining service life in conjunction with finding out the model which can be used to predict remaining service life of road pavement.
