Abstract
A substantially permanent pavement marking system using a polymer modified cement material to provide a raised marking that extends above the surface of the pavement. The lines are formed by taping off the desired outline shape of the marking. The pavement marking material is of such a consistency that it will set up to form a thick layer and not flow over the tape and will harden forming a raised marking.
Claims6
A marked pavement surface comprising:
- a) a paved asphalt surface;
- b) a polymer modified cement marking compound formed on said paved asphalt surface to mark said surface with pavement indicia;
- c) said marking compound having a mixture of acrylic resin, sand, cement and water of such consistency that it will set up before substantial spreading can occur and harden to form a raised marking;
- d) a colored sealer layer formed over said polymer modified cement marking compound which soaks into said marking compound thereby permanently coloring said marking compound.
