Inlaid Traffic Lane Lines: I-90, Edgewick Road to Hyak

Description: Three types of striping materials installed in recessed grooves are evaluated for reflectivity and durability. Initial performance evaluations have two of the materials showing very little wear and providing good daytime delineation but marginal nighttime delineation. The other material is showing considerable damage in the form of cracking and spalling and is providing good nighttime delineation but only marginal daytime delineation due to the loss of material.
