Abstract	This report analyzes possibilities for developing an alternative to the present technology of 100% acrylic waterborne (WB) paints used for road delineation. The current market situation is briefly reviewed, and alternatives considered. The requirements of an alternative technology are: Similar or lower cost in terms of price/foot/year; Longer lasting performance; and Similar or better application constraints, namely "drying time". The report suggests interim steps to improve the cost-effectiveness of existing technologies through performance-based standards. It then goes on to determine what resources would be needed to bring to "proof of concept" stage an alternative coating that would meet the stated requirements. The final recommendations of this report include the revision of the procurement specification for waterborne traffic paints, the development of a test deck for traffic paints in New Hampshire, a detailed and careful research and development program to develop new retroreflective beads and new waterborne paints containing hybrid polyurethane-acrylics binders prepared by mini-emulsion polymerization.
