Abstract

Road pavement design must meet roadworthiness requirements to ensure user safety and comfort. One factor is road surface roughness, because low roughness can cause slippery roads and increase the risk of accidents due to vehicle slippage. Road surface roughness testing using the British Pendulum Tester (BPT) is one of the parameters to determine the roughness value. Roadworthiness requirements also apply to asphalt modifications, such as the use of Glycelin Pitch (GP) type oleochemical waste as a substitute for 60/70 pen asphalt. Roadworthiness requirements in this modification are a series of advanced tests, where various tests conducted before paving have been carried out in previous studies and meet the 2018 Bina Marga Technical Specifications Revision 2. This study focuses on road surface roughness testing with the aim of proving that GP can be used as a substitute for penetration asphalt with a content of 27% (GP1) and 14.2% (GP2). The test results showed that the mixture with GP1 provided a higher British Pendulum Number (BPN) value of 80.70 compared to GP2 which was 72.20, while the BPN value for the AC-WC control mixture was 74.50. The average surface temperature in this test was 35.4°C for the GP2 sample and 37.5°C for the GP1 sample. Based on the recommended minimum friction resistance value reference for wet conditions, the GP1 and GP2 mixtures meet the safety requirements for various types of road locations, including locations with high friction such as roundabouts and sharp turns. Thus, the GP mixture shows good potential for application on roads that require high friction, supports traffic safety, and meets road function standards.

Abstract

The increasing number of passengers and flights at Jenderal Ahmad Yani Airport Semarang is predicted to continue to increase after the Covid-19 pandemic. According to data, the increase that occurred after the pandemic increased by 57% in the period 2021-2023. This increase has the potential to affect the condition of the runway pavement. In 2018, maintenance activities on the runway that have been carried out with the Overlay and Leveling method are planned to maintain pavement conditions until 2038 or 20 years of service life. To anticipate these conditions, flight traffic forecasting is required based on existing conditions until the end of the planning service life. The forecasting results show that the number of passengers can reach 14,369,352 people, which exceeds the planning of only 5,700,000 passengers. With a significant increase in the number of passengers, the results of the evaluation of pavement conditions using the COMFAA and FAARFIELD mechanistic program approaches are represented in the CDF (Cumulative Damage Factor) value. Stating in 2038 the CDF value = 21.25 with a remaining life of 0.9 years. That way the increase that occurs causes significant damage, therefore the rehabilitation process recommended by the FAA is needed with a top layer thickness of 100mm, with implementation carried out in 2026 or when the remaining 5 years of pavement life.

Abstract

Asphalt concrete waste in the Materials Laboratory of the Civil Engineering Department at Politeknik Negeri Bandung (POLBAN) reaches approximately 326 kg per year, potentially causing environmental impacts if not managed properly. This research aims to recycle asphalt concrete waste at high contents (50% and 75% of the total asphalt mixture weight) using coconut shell bio-asphalt as a rejuvenator in Asphalt Concrete-Wearing Course (AC-WC) mixtures. These recycled mixtures are intended to be reused as patching materials for road damage within the POLBAN campus. The three mixtures were evaluated using the Marshall method, focusing on determining the optimum asphalt content (OAC), stability, flow, Marshall quotient (MQ), voids in the mix (VIM), immersion index (II), voids in mineral aggregate (VMA), and voids filled with asphalt (VFA). The results showed that the mixture containing 50% asphalt concrete waste with 8.0% bio-asphalt (by asphalt weight) produced an OAC of 5.0%, a stability of 1603.3 kg, a flow of 4.0 mm, and an MQ of 396.9 kg/mm. Meanwhile, the mixture with 75% asphalt concrete waste and 8.0% bio-asphalt achieved an OAC of 4.7%, a stability of 973.8 kg, a flow of 3.8 mm, and an MQ of 255.9 kg/mm. Both mixtures met the 2018 Bina Marga Revision 2 specifications for AC-WC layers. Based on these results, it can be concluded that asphalt mixtures in the POLBAN materials laboratory can be reused as hot mix AC-WC mixtures up to a 75% waste content. This researchtuga demonstrates the potential for utilizing asphalt concrete waste as patching material for campus roads at POLBAN.
