- Abstract
In the service life of traffic markings, the visibility of the markings can be significantly impacted due to continuous rolling by vehicles. This study aims to investigate the change of retroreflective coefficient of traffic markings at different positions on the road after being rolled by vehicles. A two-month follow-up study was conducted on a specific section of the road, focusing on the sideline and middle line of the lane. The retroreflective coefficient instrument was utilized to collect data on the retroreflective coefficient of the markings. Results revealed that the middle line, due to more frequent vehicle rolling, exhibited a larger range in its retroreflective coefficient as compared to the sideline of the lane. The change in reflection ability of hot melt markings, when rolled by the vehicle, depends on the mosaic condition of the glass beads within the coating. It was observed that the rolling of the vehicle had a direct impact on the retroreflective coefficient of the hot melt marking line. Furthermore, it was found that with increased rolling of the marking line, the greater the impact on its reflection capacity and the thickness also demonstrated a significant decrease.
