Abstract

Pavement markings are vital for traffic safety, directly impacting the safety of road users. Traditional marking paints face significant issues, including high volatile organic compound (VOC) emissions and poor visibility at night, which contribute to environmental pollution and compromise driving safety. Therefore, an innovative composite silicon film coating technology was proposed, and the strontium aluminate (SA) (SrAl₂O₄:Eu²⁺, Dy³⁺) powder with good water resistance and organic compatibility was successfully realized. On this basis, through orthogonal tests and road performance verification, we developed a durable and eco-friendly water-based energy storage luminous pavement marking coating. The test results showed that the initial brightness value and 8-hour brightness value of the waterborne coating are 21.5 % and 50.0 % higher than those of the hot-melt coating, respectively, and its adhesion, skid resistance, and VOC emission are far superior to the specification requirements. This research result provides powerful guidance and support for sustainable traffic construction.

期刊介绍： Transportation Research Part D: Transport and Environment focuses on original research exploring the environmental impacts of transportation, policy responses to these impacts, and their implications for transportation system design, planning, and management. The journal comprehensively covers the interaction between transportation and the environment, ranging from local effects on specific geographical areas to global implications such as natural resource depletion and atmospheric pollution. We welcome research papers across all transportation modes, including maritime, air, and land transportation, assessing their environmental impacts broadly. Papers addressing both mobile aspects and transportation infrastructure are considered. The journal prioritizes empirical findings and policy responses of regulatory, planning, technical, or fiscal nature. Articles are policy-driven, accessible, and applicable to readers from diverse disciplines, emphasizing relevance and practicality. We encourage interdisciplinary submissions and welcome contributions from economically developing and advanced countries alike, reflecting our international orientation.
