Application of types of temporary/removable pavement marking material and special linestriping material

Delaware’s standard temporary and permanent work zone markings usually use waterborne paint. The state uses temporary tape on diagonal temporary lines where these lines go across the final or UAC surface, to leave as little scarring as possible. On high-speed / high-volume merges and shifts crews use RPMs offset 9-12 inches from edgelines to help delineate lines during rainy nights.
