A retroreflective element that exhibits exceptional wet retroreflectivity, and a method of manufacturing the same. The retroreflective element includes an assembly having a multi-sided retroreflector and a clear thermoplastic. In one embodiment, the clear thermoplastic is at least partially thermally deformed to create a convex retroreflective dome for capturing high incident angle light rays. The retroreflective elements may be used in a pavement marking system, such as attached to pavement marking tape or deposited in pavement marking paint.

[ What is claimed is:] [1.] In combination:(a) an adhesive material, and(b) a plurality of discrete rigid retroreflective elements each comprising a multi-sided retroreflector and a clear thermoplastic resin encasing the multi-sided retroreflector, the retroreflective elements adhered by the adhesive material to a surface at random orientations with respect to each other to provide non-directional retroreflection.
