DURABILITY OF REFLECTORISED ROAD MARKINGS

This paper has a two-fold purpose. First, it puts forward a simple yet basic explanation as to how the initiation of "chipping" failure in a reflectorized road-marking material is associated with the presence of the glass beads in the composite system. Secondly, it suggests that there may be an optimum bead content and gradation from the point of view of the durability of a road marking, and that this optimum could possibly be different from the optimum for reflectivity. Photographic evidence obtained with the scanning electron microscope is presented in support of the above main theses. Suggestions are made regarding further research needs in this area. /AUTHOR/
