METHOD OF FORMING AN INLAID PATTERN IN AN ASPHALT SURFACE

摘要

This application relates to a method of forming an inlaid pattern in an asphalt surface. The pattern may be selected for functional or decorative purposes. 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. The heating method permits direct visual monitoring of the work site to achieve optimum thermoplastic adhesion to the asphalt substrate.
