Retroreflective pavement marking material comprising on the top surface thereof an enclosed-lens retroreflective sheet that comprises a monolayer of retroreflective elements wherein first portions of the monolayer are arranged in an upwardly contoured profile and second portions of the monolayer are arranged a lower, substantially planar position.

Wet retroreflective marking material

A method of making a retroreflective marking material is provided, the method has the steps of: (a) providing an enclosed-lens retroreflective sheet having a top surface and a bottom surface and comprising a cover layer and a monolayer of retroreflective elements; (b) applying a conformance layer to the bottom surface of the retroreflective sheet; and (c) laminating a configuration member to the conformance layer thereby creating first portions and second portions in the sheet, the first portions being arranged in an upwardly contoured profile and the second portions being arranged in a lower, substantially planar position. A retroreflective article made by the method is also provided.
