Application of types of temporary/removable pavement marking material and special linestriping material; Type of special
Nevada DOT uses various marking products for temporary or removable situations. Temporary marking films (removable) are typically used on PCCP surfaces for short durations, as they tend to leave the adhesive backing on the surface when removed if the product is down for a longer duration or when there is high-volume traffic. Other products used are a waterborne material with approximately 1/2 the mil thickness of a permanent application. This product would then be sandblasted or waterblasted off to allow the permanent products to be placed. On asphalt surfaces, marking films (removable) will be used if multiple lane configuration changes are anticipated. If the surface is to be cold-milled or overlaid with minimal traffic pattern changes, then waterborne products are used.
Raised pavement markers have been used in non-snow plow locations if the traffic patterns are of a longer duration with minimal changes. Otherwise, standard marking products are still used, i.e. waterborne or marking films. Nevada does not get a lot of rain typically, so wet pavement is not a major concern, although it is still a problem when moisture is encountered. During “winter shut down” situations, a semi-permanent marking standard is used by placing a permanent waterborne mil thickness or marking film until work can be resumed the following construction season.
