Walter Workzone Speaks up About Pavement MarkingsAbstract:
This interview with Walter Workzone, the third in a series, discusses pavement markings. It provides an explanation from the Texas MUTCD of what the various lane line patterns and widths indicate to drivers regarding lane changing. It also states that the “Do Not Change Lanes” sign should be used in all work zones. Thermoplastic paint use for markings has increased dramatically in the 1990’s. It has a longer service life than normal highway paint. Because of this, road crews need to paint less frequently, decreasing their exposure to work vehicles. Raised retroreflective markers are also used, and provide better visibility at night and during rainy weather than painted markings.
