ABSTRAK
Kondisi perkerasan jalan berperan penting dalam mendukung kelancaran transportasi. Ruas Jalan Palu–Bangga segmen Palupi mengalami peningkatan volume lalu lintas seiring perkembangan wilayah. Penelitian ini bertujuan menganalisis kinerja struktur perkerasan eksisting terhadap beban lalu lintas aktual menggunakan aplikasi Kenpav-Kenlayer. Data yang digunakan meliputi lalu lintas, tebal lapisan perkerasan, dan karakteristik material. Analisis mekanistik-empirik menghasilkan nilai tegangan sebesar –3,72E+01 strain serta regangan sebesar 9,02E–01 strain. Repetisi beban meningkat seiring pertambahan waktu dan akan mencapai nilai repetisi beban ijin saat mencapai rutting sebesar 1.788,415,859 ESAL akan dicapai pada tahun ke 20 sebesar 1.875,743,030 ESAL atau akan mengalami keadaan failure akibat rutting setelah tahun ke-20. Sedangkan repitisi beban ijin fatigue creacking dan permanent deformation belum mengalami failure saat umur rencana mencapai ke-20 tahun. Remaining service life untuk fatigue creacking masi berada 60,73%. Sedangkan Remaining service life untuk permanent deformation masi berada pada 78,95%

Study on the Structural Performance of Road Pavement Using Kenpave–Kenlayer Applications

ABSTRACT
The condition of pavement plays a crucial role in supporting smooth and efficient transportation. The Palu–Bangga Road, particularly the Palupi segment, has experienced an increase in traffic volume in line with regional development. This study aims to analyze the performance of the existing pavement structure under actual traffic loads using the Kenpave–Kenlayer application. The data used include traffic volume, pavement layer thickness, and material characteristics. The mechanistic–empirical analysis produced a tensile stress value of –3.72E+01 strain and a compressive strain value of 9.02E–01 strain. Load repetitions continue to increase over time and are projected to reach the allowable load repetition for rutting, amounting to 1,788,415,859 ESAL, in the 20th year with an accumulated traffic loading of 1,875,743,030 ESAL. This indicates that failure due to rutting will occur after the 20th year. Meanwhile, the allowable load repetitions for fatigue cracking and permanent deformation have not reached failure by the end of the 20-year design life. The remaining service life for fatigue cracking is still at 60.73%, while the remaining service life for permanent deformation remains at 78.95%.
