Abstract:
Composite pavement markings with improved wear resistance and other advantages are disclosed. The composite pavement markings typically include a unitary retroreflective article attached to a base pavement marking. With the composite construction, different portions of the pavement marking are provided at different heights. The taller portions of the pavement marking may preferably offer some protection to the shorter portions from wear caused by vehicle traffic and/or snowplow blades. By combining two different retroreflective pavement markings to form the composite pavement markings of the present invention, a combination of features and properties may be obtained that is provided by neither of the pavement markings alone. Methods of manufacturing composite pavement markings are also disclosed.
