I need a square reflective road marker for use as a surveying target on pavement. The marker should be 3 feet by 3 feet and have the black and white pattern as in the link below. It should be flexible, HIGHLY reflective, for application to asphalt or concrete pavement. Adhesive backing should require a heat treatment for permanent bonding. Thermoplastic is acceptable.
