This report documents study of the field performance of an inlay type thermoplastic pavement marking material along with the two-year-old bituminous pavement to which it was applied. Evaluation included physical performance of the product and the effect on overall durability of the pavement surface. The installation was performed in May, 2006 on a bituminous test cell at MnROAD's Low Volume Road. 524 square feet of inlaid thermoplastic pavement marking material were installed on a surface of 4 in. Superpave hot mix asphalt, including one segment installed along 100 ft of the left wheel path of a lane that received standard truck load configurations, and two crosswalks that received load configurations that varied by lane. During the period between May 16, 2006 and August 1, 2007 Cell 26 received 6,809 and 2,003 repetitions of the standard 80K and overloaded 102K truck configurations respectively. The installation was a decorative treatment, not a retrofit of longitudinal lines on the existing pavement.
