Abstract

This study aims to analyze the effect of asphalt heating duration and asphalt mixture aging simulation on the performance of stiffness, creep, and fatigue of road pavements. The research was conducted experimentally, with samples obtained from 30 asphalt core drillings in the field, each subjected to six treatments consisting of V1 (1 hour), V2 (2 hours), V3 (3 hours), V4 (6 hours), V5 (7 hours), and V6 (8 hours), all at a temperature of 155°C. Each variation consisted of five samples tested for asphalt properties, including penetration (SNI 2456:2011), ductility (SNI 2432:2011), viscosity (SNI 7729:2011), softening point (SNI 2434:2011), flash point (SNI 2433:2011), and fire point (SNI 2433:2011). The results showed that asphalt properties varied significantly with heating duration (V1–V6), indicating that longer heating had a clear impact on asphalt characteristics. The penetration values obtained for V1 to V6 were 67.17, 64.6, 62.4, 62.2, 58.75, and 49.5, respectively, while the viscosity values were 211 seconds, 206 seconds, 201 seconds, 198 seconds, 193 seconds, and 190 seconds. The softening points were 41.5°C, 43.5°C, 44.5°C, 45°C, 46°C, and 47°C, while the flash points were 318°C, 325°C, 329°C, 330°C, 332°C, and 335°C. The fire points were 330°C, 332°C, 335°C, 340°C, 345°C, and 350°C. The stability values of the mixture increased with heating duration, reaching 1883.5 kg, 2040.5 kg, 2130.2 kg, 2175.0 kg, 2197.4 kg, and 3254.4 kg. Conversely, the flow values decreased, becoming 3.81 mm, 3.05 mm, 2.79 mm, 2.29 mm, 2.16 mm, and 1.91 mm. The average Marshall quotient values for each heating variation were 494.36 kg/mm, 669.45 kg/mm, 762.41 kg/mm, 951.45 kg/mm, 1017.81 kg/mm, and 1235.91 kg/mm. This study can help optimize asphalt heating duration to improve pavement quality and durability. The findings also have the potential to serve as a basis for refining standards and policies in the design and maintenance of more resilient road infrastructure.

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.
