Glass Bead Retention Test to Evaluate Road Marking Performance

A system to evaluate force required to dislodge glass beads from a road marking composition, the system comprises:

• a platform for applying a road marking composition onto a substrate, forming a road marking layer on the substrate at a pre-determined thickness;
• means for positioning at least a glass bead in the road marking layer for testing;
• a tensile tester for measuring force required to dislodge the glass bead from the road marking layer;
• and
• a gripping component operably coupled with the tensile tester for locking the glass bead in position while the tensile tester applies a force on the glass bead to fully dislodge the glass bead from the road marking layer.
