ABSTRAK
Kondisi perkerasan jalan yang baik penting untuk mendukung kelancaran transportasi. Jalan Nambo di Kota Palu mengalami peningkatan lalu lintas sehingga perlu dilakukan evaluasi terhadap kinerja strukturnya. Penelitian ini bertujuan menilai kinerja perkerasan eksisting Jalan Nambo menggunakan perangkat lunak Kenpave dan Kenlayer. Analisis Kenpave-Kenlayer dilakukan berdasarkan data lalu lintas, tebal lapisan, dan karakteristik material. Analisis mekanistik-empirik menghasilkan nilai tegangan sebesar –3,596E-01 strain serta regangan sebesar 8,480E-03 strain. Repitisi beban ijin fatigue creacking, ruttig dan permanent deformation belum mengalami failure saat umur rencana mencapai ke-20 tahun sebesar 422.372.160 ESAL. Remaining service life untuk rutting masih berada 57,96%. Remaining service life untuk fatigue creacking masih berada pada 68,43%. Sedangkan Remaining service life untuk permanent deformation masi berada 88,03%.

ABSTRACT
A good pavement condition is essential to support smooth and efficient transportation. Nambo Road in Palu City has experienced an increase in traffic volume, necessitating an evaluation of its structural performance. This study aims to assess the performance of the existing pavement structure on Nambo Road using Kenpave and Kenlayer software. The Kenpave–Kenlayer analysis was conducted based on traffic data, layer thicknesses, and material characteristics. The mechanistic–empirical analysis produced a stress value of –3.596E-01 strain and a strain value of 8.480E-03 strain. The allowable load repetitions for fatigue cracking, rutting, and permanent deformation indicate that no failure occurs within the 20-year design life of 422,372,160 ESAL. The remaining service life for rutting is 57.96%, for fatigue cracking is 68.43%, and for permanent deformation is 88.03%.
