Traffic paint is the primary pavement marking material used on state maintained highways in North Carolina. Annually over 1.5 million gallons of traffic paint are used for the road marking in North Carolina. The North Carolina Department of Transportation (NCDOT) traditionally has used premixed traffic paints for its painting program. There have always been questions about wheather the reported benefits of a premixed traffic paint system outweigh the costs associated with equipment problems, crew downtime, special handling procedures, etc. This research was designed to determine the performance and life cycle cost of premixed and plain traffic paints under inservice conditions. Six different paint products were tested in this research: three premixed and three plain paints. Both white and yellow markings were tested. Testing was performed under normal highway conditions on 84 one mile long test sections, over a 52 month period. Markings were evaluated for appearance, durability, retroreflectivity, and nighttime visibility. A detailed equipment evaluation was also conducted. Based on the performance data and the equipment repair data a life-cycle cost analysis was performed on all of the paints tested.
