3M Stamark Liquid Pavement Markings

Pavement markings usually deteriorate quickly and sometimes in an unpredictable manner. The NDDOT needs a cost-effective long-term pavement marking system that lasts longer than the available water- based paints. When water-based paint looses its effectiveness, another application cannot be applied because of the climate. The objective of this study is to determine if 3M Stamark Liquid Pavement Marking Series 1200 is cost effective and more durable than presently used water-based paint. Initial retroreflectivity readings were higher than conventional water-based paint but lower than manufacturer claims. The experimental test section was remarked with a water-based paint before the second evaluation. Because the experiment had been compromised it will be terminated.
