Abstract

A method for molding a pattern on the surface of heated asphalt. The method includes: providing an asphalt molding mesh comprising pattern molding elements formed of an elastic material having a V-shaped cross-section in a configuration corresponding to a pattern to be molded in the asphalt. The mesh is then heated to substantially equalize with that of the surface of the asphalt. The mesh is positioned and inserted at least partially into the asphalt. The mesh and asphalt are rolled over to mold the asphalt and compact the asphalt about the mesh. Water is applied to the surface of the asphalt while rolling to limit the heating and expansion and buckling of the mesh. Finally, molding mesh is removed from the asphalt.
