| 摘要： | This report describes in-service performance of about 240 miles of white and yellow polyester pavement markings on four striping-contract projects. They were installed on low-volume roadways, on both existing asphalt concrete surfaces over worn paint lines and on new asphalt surfaces at least a month old. Most striping was in good to fair condition after 2 1/2 years of service, providing acceptable daytime delineation. Although the white markings had good nighttime reflectivity, most of the yellow stripping was rated only fair. Based on this evaluation, polyester appears capable of providing effective pavement markings for up to 2 1/2 years on low-volume roads (AADTs less than 4000). |
