Abstract
This review paper examines the environmental and functional issues associated with existing road marking technology and proposes eco-friendly alternatives to address them. In particular, it focuses on technologies utilizing fluorescent (luminous) and retroreflective materials. Traditional paints are typically petroleum-based, emit volatile organic compounds (VOCs), contribute to greenhouse gas emissions, and wear out quickly. On the other hand, EcoMark Road absorbs sunlight and emits light on its own in dark environments. The fluorescent layer utilizes Eu, Dy-doped SrAl2O4, demonstrating excellent performance of 6 to 12 hours during both day and night. Retroreflective paint reflects the headlights of a vehicle back to the driver, improving visibility. This project proposes a hybrid system that combines self-luminous and retroreflective functions by integrating these two technologies and utilizing water-soluble and biodegradable binders. This paper will cover the scientific principles, performance, environmental impact, empirical data, and sustainable development goals of this technology, and comprehensively examine the possibility of linking it with the SDGs (Sustainable Development Goals).
