Analisis Pengaruh Beban Muatan Berlebih Pada Kendaraan Berat Terhadap Umur Rencana Jalan (Studi Kasus Ruas Jalan TGH. Saleh Hambali Sandubaya, Kota Mataram)

Abstract

Abstract: The TGH. Saleh Hambali–Sandubaya road section in Mataram City is a primary arterial route that serves the movement of heavy vehicles transporting commercial goods. The high intensity of heavy vehicles and the occurrence of vehicle overloading have the potential to accelerate pavement deterioration and reduce the design life of the road. This study aims to analyze the effect of excessive axle loads on heavy vehicles on the design life of the road section. The study employed a quantitative descriptive approach using primary data from a 24-hour traffic survey and secondary data consisting of freight vehicle data and weighing results from UPPKB Bertais in 2025, road classification data, and road reconstruction data. The analysis was conducted based on the 2024 Bina Marga Method through the processing of Average Daily Traffic (LHR), projection of Annual Average Daily Traffic (LHRT) using a traffic growth factor of 4.75%, calculation of the Vehicle Damage Factor (VDF), Equivalent Single Axle Load (ESAL), Cumulative Equivalent Single Axle Load (CESAL), and remaining life. The survey results recorded a total of 1,871 heavy vehicles in both directions, while the Road Class Determination Data Based on Function and Traffic Intensity, as well as the Capacity to Carry the Heaviest Axle Load and Motor Vehicle Dimensions, specifies a maximum allowable axle load of 10 tons. The identified overloaded vehicle groups included 6A, 6B, 7A1, and 7C1. The initial-year ESAL value increased from 1,669 under standard loading conditions to 3,855 under overloaded conditions. The final CESAL over the 10-year period reached 10,156 and 23,464, respectively. Interpolation results indicate an effective pavement life of approximately 5.850 years under overloaded conditions, representing a reduction of 4.150 years from the original 10-year design life. These findings indicate that vehicle overloading significantly accelerates the consumption of pavement service life.

Abstrak: Ruas Jalan TGH. Saleh Hambali-Sandubaya di Kota Mataram merupakan jalur arteri primer yang melayani pergerakan kendaraan berat pengangkut barang niaga. Intensitas kendaraan berat dan kejadian muatan berlebih berpotensi mempercepat kerusakan perkerasan dan mengurangi umur rencana jalan. Penelitian ini bertujuan menganalisis pengaruh beban muatan berlebih pada kendaraan bera t terhadap umur rencana ruas jalan tersebut. Penelitian menggunakan pendekatan deskriptif kuantitatif dengan data primer berupa survei lalu lintas selama 24 jam dan data sekunder berupa data kendaraan angkutan barang serta hasil penimbangan dari UPPKB Bertais tahun 2025, data kelas jalan, dan data rekonstruksi jalan. Analisis dilakukan berdasarkan Metode Bina Marga 2024 melalui pengolahan LHR, proyeksi LHRT dengan faktor pertumbuhan lalu lintas 4,75%, perhitungan Vehicle Damage Factor (VDF), Equivalent Single Axle Load (ESAL), Cumulative Equivalent Single Axle Load (CESAL), serta remaining life. Hasil survei menunjukkan total 1.871 kendaraan berat dua arah, sedangkan Data Penetapan Kelas Jalan Berdasarkan Fungsi Dan Intensitas Lalu Lintas Serta Daya Dukung Menerima Muatan Sumbu Terberat Dan Dimensi Kendaraan Bermotor maksimal 10 ton . Kendaraan overload yang teridentifikasi meliputi golongan 6A, 6B, 7A1, dan 7C1. Nilai ESAL tahun awal sebesar 1.669 pada kondisi standar meningkat menjadi 3.855 pada kondisi overload. CESAL akhir periode 10 tahun masing-masing mencapai 10.156 dan 23.464. Hasil interpolasi menunjukkan umur efektif akibat overload sekitar 5,850 tahun, sehingga terjadi penurunan umur rencana sebesar 4,150 tahun dari umur rencana 10 tahun. Temuan ini menunjukkan bahwa muatan berlebih memberikan pengaruh signifikan terhadap percepatan konsumsi umur layanan perkerasan.
