40
Pavement StripingVisimaxTM Wet Reflective Beads2-CompleteThis successful proof of concept was the foundation of subsequest research that is currently in progress
41
Pavement StripingWet Night Bead Comparisons2-CompleteVisual inspection in the fall of 2013 showed the new, ungrooved water based paint with regular beads in was brighter in the rain than the wet night, year old, applications. We will reapply the test deck in another location that has a flatter profile so run-off is more consistent between product applications.
42
Pavement StripingState Spec Beads and 3M Elements On I-842-CompleteProject was painted over 2 years later because groove wasn't deep enough to protect this application.
