    Abstract: This application relates to a method of applying a thermally settable coating to a patterned substrate, such as an asphalt surface. The coating is applied in one or more preformed thermoplastic sheets and heated in situ to conform the thermoplastic material to the pattern formed in the underlying substrate. In one embodiment of the invention a pattern is formed in the asphalt surface using a removable template which is impressed into the asphalt when it is in a pliable state. The pre-formed sheets are then applied to the patterned surface and gradually heated. In an alternative embodiment of the invention the template is impressed into the pre-formed sheet and asphalt surface simultaneously after the sheet has been heated to a suitable temperature in situ. A bond reduction agent may be used to minimize adhesion between the template and the heated thermoplastic material. In a further alternative embodiment of the invention the thermoplastic material may be stamped after it has melted and partially cooled to cause the thermoplastic to more precisely conform to the underlying pattern.

    Abstract: In one embodiment the method comprises the steps of providing a first template having a predetermined pattern; impressing the first template into the asphalt surface when the asphalt surface is in a pliable state to form an impression therein; removing the first template from the asphalt surface to expose the impression; providing a second template having a predetermined pattern matching the pattern of the first template; inserting the second template into the impression; and fixing the second template in position within the impression to form the inlaid pattern. The second template may consist of a preformed thermoplastic grid having a color and/or texture contrasting with the asphalt surface. In another embodiment the second template may include a light source for illuminating the template after it has been fixed in position. A heating method is described for gradually heating large asphalt surfaces using a reciprocating bank of infrared heaters to thermally fix the thermoplastic grid in place.
