Abstract

The increase in urban transportation in the 2000s era was very high. The use of motorized vehicles during the pandemic has decreased slightly with the government's ban on traveling out of town, including the 2020 homecoming and 2021 homecoming. Most people who travel are in the city center, including the city of Bogor and Bogor district. The travel patterns are very diverse, but most use public transportation and private transportation in addition to freight transportation with a fairly high intensity, especially at night. The purpose of this study was to obtain the LoS value at the signalized intersection of the three arms of the Salabenda intersection. The three-arm Salabenda intersection is the border between Bogor regency and the city of Bogor, so this intersection is one of the busiest and most densely populated intersections beside the Ciawi intersection in the north. The Salabenda intersection has become more congested with the opening of the Section IIIA Toll Road so that the traffic load shifts from Jl. KH. Sholeh Iskandar to this toll road, so that the intersection will have a higher traffic intensity. From the three observations and data collection in the field, it can be seen that in the afternoon it has a very high LoS, namely E. Followed by a LoS D level in the afternoon and in the morning LoS is still in the form of C. So it is still safe to use in the morning with a recommended level. The LoS E condition is a condition where the intersection has a degree of saturation of 0.926, which is almost close to 1, exacerbated by high side resistance activity.

Abstract

This study aims to evaluate the accuracy of IRI prediction using the MEPDG 2015 method with two different local calibration parameters—New Mexico and Virginia—by comparing them against actual field conditions in Indonesia. The analysis was conducted on six segments of the North Coast National Road (Pantura), totaling 55.87 km, using input data from 2020 and field measurements from 2021 to 2023. Pavement responses were analyzed using ELMOD 6 and KENPAVE, and predictions were made for rutting, fatigue cracking, and IRI. The results showed that MEPDG 2015 with Virginia calibration produced the smallest relative deviation (?15.66%) compared to the field data, indicating better alignment with actual pavement performance than the New Mexico calibration. The findings confirm the importance of selecting calibration parameters appropriate to local climate and structural conditions. MEPDG 2015 with Virginia calibration is recommended for future IRI prediction in areas with similar environmental characteristics to western Indonesia.

Abstract

Keterbatasan bahan alam untuk perbaikan jalan mendorong pemanfaatan material daur ulang, termasuk campuran perkerasan daur ulang yang distabilisasi semen (CTRB). Namun, CTRB memiliki kelemahan berupa kerentanan terhadap retak susut yang dapat memicu retak reflektif pada lapisan permukaan. Penelitian ini mengevaluasi kinerja CTRB dan campuran serupa yang ditambahkan aspal emulsi (IRBCAE-In-place Recycling with Cement and Asphalt Emulsion) untuk mengurangi potensi retak susut. Kedua campuran dirancang menggunakan agregat daur ulang dengan kadar aspal sisa sebesar 5,34%, serta komposisi agregat lapis permukaan dan fondasi masing-masing 49% dan 51%. Pengujian modulus resilien dilakukan untuk menilai kinerja mekanis, sedangkan analisis respons struktural dilakukan melalui pemodelan menggunakan perangkat lunak KENPAVE. Hasil menunjukkan bahwa IRBCAE bersifat viskoelastis dengan ketahanan retak lelah yang lebih baik, sedangkan CTRB lebih kaku dan unggul dalam menahan deformasi permanen. Dalam penerapannya, CTRB memerlukan lapisan aspal yang lebih tebal untuk mencegah retak reflektif, sedangkan IRBCAE memungkinkan penggunaan lapisan yang lebih tipis. Perbedaan kinerja struktural antara kedua campuran tersebut dapat menjadi pertimbangan dalam memilih metode stabilisasi lapis pondasi daur ulang.

Abstract

Abstrak Penelitian ini bertujuan membandingkan akurasi metode prediksi kondisi jalan antara MEPDG 2015 dan IRMS V.3 sebagai dasar pemrograman preservasi jalan pada skala jaringan. Studi dilakukan pada enam ruas jalan nasional Pantura sepanjang 55,87 km dengan karakteristik lalu lintas beragam. Prediksi IRI metode MEPDG 2015 dihitung menggunakan pendekatan mekanistik-empiris dengan tiga jenis kalibrasi (Global, Arizona, dan Oregon), serta bantuan software ELMOD 6 dan KENPAVE. IRMS V.3 menggunakan pendekatan empiris berbasis data historis. Hasil prediksi dibandingkan dengan data aktual tahun 2021–2023 untuk menghitung deviasi relatif, kemudian dianalisis dalam program preservasi selama 20 tahun dengan dua skenario: unconstrained budget dan constrained budget menggunakan Back-fall Strategy (strategi menunda, bertahap, dan holding). MEPDG 2015 kalibrasi Oregon menunjukkan deviasi relatif terkecil (−15,48%) dan merupakan metode paling akurat. Dalam kondisi tanpa batasan anggaran, metode ini lebih hemat dibanding IRMS V.3. Dalam keterbatasan anggaran, strategi holding dengan MEPDG 2015 menghasilkan kemantapan jalan akhir 2–3 kali lebih tinggi bila dibandingkan dengan strategi lain, meskipun biayanya 1–2% lebih besar. Dengan demikian, MEPDG 2015 kalibrasi lokal Oregon dengan strategi holding direkomendasikan sebagai strategi terbaik saat terjadi keterbatasan anggaran di skala jaringan. Kata-kata Kunci: Back-fall strategy, IRMS V.3, MEPDG 2015, preservasi. Abstract This study aims to compare the accuracy of road condition prediction methods between MEPDG 2015 and IRMS V.3 as a basis for network-level road preservation programming. The study was conducted on six continuous segments of the Pantura national road spanning 55.87 km with varying traffic characteristics. IRI prediction using the MEPDG 2015 method was calculated based on a mechanistic-empirical approach with three calibration types (Global, Arizona, and Oregon), supported by ELMOD 6 and KENPAVE software. Meanwhile, IRMS V.3 applies an empirical approach based on historical data. The prediction results were compared with actual field data from 2021–2023 to calculate relative deviation and analyzed in a 20-year preservation program under two budget scenarios: unconstrained and constrained budget using the Back-fall Strategy (postponed, gradual, and holding strategies). MEPDG 2015 with Oregon calibration showed the smallest relative deviation (−15.48%) and was the most accurate method. Under an unconstrained budget, it was also more cost-efficient than IRMS V.3. Under budget constraints, the holding strategy with MEPDG 2015 produced 2–3 times higher final road condition performance when compared to other strategies, despite requiring 1–2% more cost. Therefore, MEPDG 2015 with local Oregon calibration and holding strategy is recommended as the best option under limited budget conditions at the network level. Keywords: Back-fall strategy, IRMS V.3, MEPDG 2015, preservation.

Abstract

Abstrak Eksistensi air dalam bentuk rendaman pada struktur perkerasan diketahui memiliki dampak yang buruk. Pemahaman yang tepat dalam menilai seberapa besar dampak yang dihasilkan, akan sangat membantu dalam melakukan evaluasi kinerja struktur perkerasan. Penelitian ini menggunakan metode yang memungkinkan untuk menganalisis pengaruh variasi tinggi muka air terhadap performa konstruksi perkerasan. Simulasi dilakukan dengan menaikkan elevasi muka air secara bertahap dari kedalaman 10 meter di bawah subgrade hingga ke subbase. Soil Water Characteristic Curve (SWCC) dimanfaatkan dalam hal ini untuk menentukan gradasi derajat kejenuhan pada subgrade dan subbase yang terjadi akibat adanya rendaman pada elevasi tertentu, yang juga mempengaruhi nilai modulus resiliennya. Metode analisis dengan 3D finite element digunakan dalam memperoleh visualisasi dan nilai regangan kritis ketika kondisi tidak jenuh hingga sepenuhnya jenuh, untuk kemudian dinyatakan sebagai nilai kinerja berdasarkan Manual Desain Perkerasan Jalan 2024 (MDP 2024). Hasil penelitian mengungkapkan bahwa kinerja struktur perkerasan lentur, terutama kinerja deformasi permanen, dinilai sangat sensitif terhadap perubahan tinggi muka air rendaman. Temuan menarik lainnya adalah identifikasi elevasi muka air dimana pengaruh yang diberikan terhadap perubahan kinerja tidak lagi signifikan, yaitu pada elevasi lebih besar dari 60 cm di bawah subgrade, yang bersesuaian dengan syarat jagaan muka air yang direkomendasikan oleh MDP 2024. Kata- kata kunci: Analisis sensitivitas, derajat kejenuhan, elevasi rendaman, finite element, kinerja perkerasan Abstract The presence of water in the form of submersion within pavement is known to have detrimental effects. A proper understanding of assessing the extent of these impacts is crucial for evaluating pavement performance. This study employs a method to analyze the influence of varying water table elevations on pavement performance. Simulations were conducted by incrementally raising the water table from a depth of 10 meters below the subgrade up to the subbase. The Soil Water Characteristic Curve was utilized to determine the saturation degree gradation in the subgrade and subbase due to submersion at specific elevations, which also affects their resilient modulus values. A 3D finite element analysis method was used to obtain visualizations and critical strain values under unsaturated to fully saturated conditions, which were then assessed as performance indicators based on Indonesia: 2024 Road Pavement Design Manual (MDP 2024). The results reveal that permanent deformation performance is highly sensitive to changes in submersion water table elevation. Another significant finding is the identification of the water table elevation which the impact on performance change becomes negligible—specifically, at elevations greater than 60 cm below the subgrade, which aligns with the recommended water table control requirement in MDP 2024. Keywords: Degree of saturation, finite element, pavement performance, sensitivity analysis, submersion elevation
