ABSTRACT:
A street marking strip device formed of a resilient and flexible strip material includes a traffic marking on a visible side thereof and a street engaging underside having longitudinally extending clearances and cavities separated by longitudinally extending contact edge zones for releasably engaging a street surface. The strip material optionally may include longitudinally extending reinforcement elements in the form of strand or sheet material and may include prestressing elements for giving the strip material an overall concave shape when it is in its unloaded condition. When the prestressed strip material engages a street surface, a clawing action results as the strip material is flattened against the street surface. The strip material may be readily released from the street surface and reused again. The strip material includes tapered flanks to ensure smooth traversal by automobiles.
