  • Method for forming traffic surfaces having double-coated bonding of anti-slip particles and containing retro-reflective beads
    Patent number: 5380549
    Abstract: A method for providing a traffic surface such as a path, roadway, passageway, deck, or airfield runway or taxiway with both anti-slip and retro-reflective characteristics. A first coating of paint is applied to the surface, solid particles are distributed onto the first coating such that the particles sink partially into the first coating, and a second coating of paint is applied over the particles and the first coating to lock the particles into the first coating with the particles projecting from the second coating. Before the second coating is set, retro-reflective beads are distributed over the second coating to sink partially into the second coating between the projecting particles. The beads are bonded into the second coating and project from the second coating. The beads are smaller than the particles and the particles project from the second coating by more than the beads to overshadow the beads.
