How To Pavement Marking Program Pavement markings are a vital safety feature on most county maintained roads. Maintaining these markings is quite expensive. Approximately 8,200 gallons of yellow paint and 9,300 gallons of white paint were applied. Roads are repainted as the stripes get worn by traffic.
Most roads require striping yearly while some require striping twice a year.
The striping program also stripes the roads involved in the Road and Bridge Department's chip seal program. Roads with a fresh chip seal surface usually require two paint applications on the road centerline. All pavement markings are retroreflective, meaning they reflect light from headlights back toward the driver. This retroreflectivity is accomplished through the introduction of glass beads into the wet paint. When the paint dries, the beads are trapped throughout the thickness of the paint.
