CA 2147711

A pavement marking material.comprises a flexible base sheet that is conformable to an irregular pavement surface. A non-continuous, durable, wear-resistant polymeric top layer is adhered to one surface of the base sheet. The discontinuous nature of the polymeric top layer provides for increased initial conformance of the pavement marking to irregular pavement surfaces. The discontinuous nature-of the polymeric top layer also reduces elastic tensile stresses which tend to build up in continuous top layers and cause adhesive failure. A plurality of particles, retroreflective microspheres and/or skid-resistant particles, are embedded in and protrude from the non-continuous top layer.
