UMHÜLLTES RETROREFLEKTIERENDES ELEMENT UND HERSTELLUNGSVERFAHREN

摘要

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.
