Abstract
A retroreflective composite bead for highway marking having high retroreflectivity both when initially installed and over the bead lifetime, allowing vehicle drivers to see highway marking lines at night and in adverse conditions during nighttime. When installed the retroreflective beads essentially retroreflect the base color of the highway marking material in which the retroreflective beads are embedded. The beads comprise a larger bead with a coating of smaller particles heat bonded to its surface.
