Abstract

Abstract The increasingly limited availability of volcanic stone in nature has caused road pavement construction materials to use black volcanic stone mixed with red volcanic stone, which is lighter in density and porous. This research aims to analyze the mechanistic performance of asphalt mixtures by substituting coarse aggregate with red volcanic stone up to a percentage of 10% at a granule size of ½", 3/8", No. 4 according to conditions in the field. The asphalt mixture is made using the marshall method. Mechanistic characteristics are obtained from indirect tensile stiffness modulus (ITSM) testing according to BS EN 12697-26: 2012, dynamic creep testing (BS EN 12697–25:2005) and indirect tensile fatigue testing (ITFT) according to BS EN 12697–24:2012 using a dynapave universal testing material (UTM) 30 test tool. The marshall characteristic values of the asphalt mixture meet the specifications of the Ministry of PUPR (2020), the stiffness characteristic increases by an average of 6.9 % for each additional substitution of 5% red volcanic stone. Deformation resistance increases with typical values of creep slope, concluding that asphalt mixtures can be used for heavy traffic loads (ESA >106). The fatigue resistance characteristics are lower (earlier to collapse) compared to without red volcanic stone substitution and there is a decrease in fatigue resistance of 2.18% for each additional 5% red volcanic stone substitution.

Abstract

Rigid pavement on airport service roads is essential for smooth vehicle operations, with subgrade conditions being the primary factor in determining concrete slab thickness. Variations in the California Bearing Ratio (CBR) of the subgrade commonly affect pavement thickness and construction costs. This study analyzes how changes in subgrade CBR impact rigid pavement thickness for service roads using the empirical method of Pd T-14-2003. It also compares the results with international standards, including FAA AC 150/5320-6G and ICAO Annex 14, to validate findings and assess the relevance of Indonesian standards globally. The research involved collecting traffic data and geotechnical parameters and calculating design thickness variations based on CBR values. Results indicate that each 1% increase in CBR decreases the required concrete slab thickness by 4 mm: 163 mm at 6% CBR, 158 mm at 7%, and 155 mm at 8%. Comparison with international standards shows that Pd T-14-2003 tends to produce conservative designs. However, integrating mechanistic-empirical approaches could improve safety and economic efficiency. These findings demonstrate that enhancing subgrade quality can reduce slab thickness, leading to material savings and lower construction costs. This study advances the traditional CBR approach by incorporating advanced soil mechanics principles and offers a framework for adopting international best practices in Indonesian airport pavement design, supporting the advancement of domestic aviation infrastructure.

Abstract

The rapid population growth in Klungkung Regency, accompanied by an increase in motor vehicle ownership, has accelerated the development of transportation in the region. Although traffic density in Klungkung is lower than that in larger cities, traffic accidents continue to occur. Therefore, identifying accident-prone areas and the contributing factors is essential. This study aims to analyze black sites and black spots, as well as to identify the factors influencing traffic accidents in Klungkung Regency. The research utilizes secondary data obtained from the Klungkung Police Department. The analysis begins with problem identification, data collection, and the application of Z-Score and Accident Equivalent Number (AEK) methods to identify black sites. Black spots are identified using the Upper Control Limit (UCL) method, followed by an analysis of accident-contributing factors. The findings reveal that 79.3% of accidents involve motorcycles, with an estimated economic loss of IDR 646,725,000. The dominant type of accident (44.71%) is loss of vehicle control, while 23% of incidents occur on Sundays, and 32.23% of the offenders are between 16 and 25 years old. Four black sites were identified: Prof. Dr. Ida Bagus Mantra Road, Raya Sampalan Road, Ngurah Rai Road, and Raya Klumbu Tokah Pakeh Road. In addition, six black spots were found: STA 0+000–0+500, STA 2+000–2+500, STA 3+000–3+500, STA 4+000–4+500, STA 5+000–5+500, and STA 7+000–7+500. Contributing human factors include careless behavior, drowsiness, sudden braking, and mobile phone use while driving. Vehicle-related causes involve brake failure, faulty lights, worn tires, and missing mirrors. Accidents are more likely to occur under clear weather conditions due to a reduced perception of risk, which can lead drivers to lower their vigilance and violate traffic regulations. This study offers an integrated analytical approach to identifying black sites and black spots while examining key accident factors. The findings are expected to support targeted strategies and serve as a reference for policymakers and traffic safety authorities in developing more effective prevention measures.

Abstract

Salah satu alternatif cara mengurangi penggunaan agregat alam dan aspal adalah penggunaan material daur ulang seperti material perkerasan jalan lama atau RAP. Aspal dalam RAP umumnya lebih kaku karena proses penuaan, sehingga perlu dicampur dengan bahan peremaja. Alternatif bahan peremaja berbasis minyak organik yang dapat digunakan untuk peremajaan aspal yang bersifat kaku adalah limbah minyak goreng/ Waste Cooking Oil (WCO). Tujuan penelitian ini menganalisis karakteristik campuran beraspal pada Kadar Aspal Optimum (KAO) dan kadar WCO terbaik. Metode pembuatan campuran beraspal yang digunakan Metode Marshall. Variasi material RAP adalah 25% dan 50%, dengan tambahan aggregat untuk memperoleh gradasi ideal. Pada setiap variasi penggunaan material RAP dibuat variasi campuran dengan peremaja WCO 2%, 4%, 6%, 8%, dan 10% (berat aspal total), dimana untuk setiap variasi RAP dengan variasi bahan peremaja WCO, dibuat variasi kadar aspal 5%; 5,5%; 6%; 6,5%; serta 7%. Kemudian nilai KAOnya ditentukan. Pada campuran dengan 50% RAP diperoleh KAO 6,3%, dan hasil terbaik pada peremaja WCO 8%. KAO pada campuran dengan 25% RAP adalah 6,2%, dengan pilihan peremaja 4% WCO. Karakteristik Marshall campuran memenuhi spesifikasi. Campuran dari 50% RAP dengan 8% WCO memiliki kekakuan dan ketahanan deformasi lebih rendah, namun demikian kinerja campuran ini cukup baik  pada uji kelelahan.

Abstract

Traffic accidents often occur due to a mismatch between road geometry and vehicle operating conditions, particularly on high-risk road sections. This study aims to evaluate road geometric conditions and design improvements for the Denpasar-Gilimanuk Highway, specifically at accident-prone locations, namely the Antosari–Tabanan City Border road segment (KM 34+100–KM 34+422). The research methodology began with data collection, including an inventory of road geometry, traffic data, and accident records. The evaluation and design of road geometry were conducted in accordance with Road Geometric Design Guidelines No. 13/P/BM/2021. The existing road geometry consists of a compound curve with radius (R) of 30 m and 120 m, without a connecting straight section, with a lane width of 6.7 m. The maximum grade (g) is 7%, with vertical curve lengths of 60 m and 80 m. These values do not meet minimum standards, thus potentially increasing the risk of accidents. The geometric redesign was carried out with two alternatives: either making it a single curve with an adjusted curve radius (R) of 130 m or 110 m and a vertical alignment gradient of 4.86% or 6.54%, with curve lengths of 150 m or 90 m, based on considerations of stopping sight distance, headlight glare, leading sight distance, and driving comfort. The design also includes widening the pavement at the curve by 1.25 m, improving roadside drainage, and installing traffic signs and road markings. This research contributes to providing a comprehensive approach in handling accident-prone locations through the integration of geometric aspects and road equipment.

Abstract

Road pavement condition is an important factor in supporting the safety, comfort, and smoothness of traffic, particularly during high traffic activity and volume, such as on the Sibang Kaja Highway in Badung Regency. As pavement service life increases and traffic load on the road infrastructure increases, various types of pavement damage on the surface begin to appear, potentially reducing the functional performance of the road. This study aims to analyze the pavement condition of Sibang Kaja Highway using the Pavement Condition Index (PCI) method and to provide recommendations for road maintenance management based on the level of damage. The research method used the PCI method through a visual field survey to identify the type, severity, and extent of pavement damage, which were then analyzed to obtain PCI values for each sample unit and road segment. The analysis results show that the dominant types of damage include alligator cracks, block cracks, patches, and raveling, with PCI values across segments ranging from poor to satisfactory. The average PCI value of 56.72 for each segment indicates that the pavement condition is in the fair category, indicating that the pavement is still functional but has experienced a decline in performance. Based on the percentage of damaged area, a combination of routine, periodic, and rehabilitation programs is recommended for specific segments. This research provides a basis for decision-making in prioritizing road maintenance and rehabilitation.
