  • Roadway median stripe protective method
    Patent number: 5782577
    Abstract: A method for protecting reflective delineator stripes includes the use of spacer beads disposed along the stripe to protect reflective beads disposed thereon. The spacer beads are of a greater diameter than the reflective beads so that snowplow blades and the like will contact the spacer beads but not the reflective beads. As the snowplow blades impact the spacer beads, the snowplow blades travel along the top of the spacer beads, thereby avoiding contact with the reflective beads.
