Abstract

External factors that affect the structure of the road pavement are the loads of traffic and the environment (temperature, weather). Fatigue cracking is one of three major distresses for asphalt pavement. One method used for fatigue analysis is classical fatigue.  This method is used to obtain an equation model which predicts the service life of a road pavement. Apart from problems like this, there needs to be innovation both in terms of materials and road pavement planning, namely by modifying the asphalt mixture, such as adding buton asphalt and crumb rubber. This research is intended to develop a Monismith model that is used to predict the fatigue life of a road pavement material. Three types of asphalt, namely 60/70 penetration asphalt, buton modified asphalt and crumb rubber modified asphalt were used in this research. The fatigue test used the Four Point Bending Test (4PBT) tools. The specimen which used to fatigue test with 4 variations of asphalt mixtures, 4 variations of temperatures at 15oC, 20oC, 25oC and 30oC.  The results of the four-point bending test showed that the Nf value (maximum number of repetitions) at a temperature of 30oC was 394,400 cycles, with 15% crumb rubber modified asphalt. The development of a fatigue model with a critical temperature approach to asphalt mechanistic rheology has resulted from this research.

Abstract

This community service program aims to improve public street lighting (PJU) access for residents of Drawati Village, Paseh District, Bandung Regency, through the utilization of renewable energy in the form of solar power. The main issue faced by the community is the lack of adequate lighting at night, which negatively affects social activities, neighborhood safety, and residents' comfort. The implementation method includes needs assessment, technical planning, procurement of solar-powered street lighting equipment, installation at strategic points, and community education on usage and basic maintenance. A total of five solar-powered streetlight units were successfully installed in locations agreed upon with local leaders and village officials. The results of the activity indicate a notable improvement in the community’s quality of life, particularly in terms of nighttime safety and increased outdoor activities after dark. Moreover, this initiative has raised community awareness of the importance of using clean and environmentally friendly energy. In conclusion, the application of simple technology such as solar streetlights can create a significant social impact and should be further developed through maintenance training and the empowerment of local communities to sustain the installed infrastructure.
