The objective of this report was to summarize the long-term performance of several types of durable lane delineation materials. Polyester paint was determined to be an effective durable lane material with most use of this material being on asphaltic concrete surfaces having an average daily traffic of under 10,000. Extruded thermoplastic was also determined to be an effective durable lane delineation material with its cost limiting its use to higher volume asphaltic concrete surfaces. Either the hydrocarbon or alkyd thermoplastic formulation could be used but the alkyd formulation was observed to maintain a higher reflectivity. While not classified as a durable marking material, waterbased paint could be used as an alternative to alkyd traffic paint.

The 3M 350 Series Stamark tape was judged as being an effective lane delineation material, but its cost would limit its use to specific areas such as high volume roads having a portland cement concrete surface.
