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.

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.

Method of forming an inlaid pattern in an asphalt surface

This application relates to a method and apparatus for heating a surface marking, such as a thermoplastic pattern in an asphalt substrate. The marking may be selected for functional or decorative purposes. The method involves gradually applying heat to the marking to avoid scorching and to ensure a consistent bond with the underlying substrate, even in the case of markings having a very large surface area. In one embodiment the method a portable heating apparatus is provided having infrared heaters mounted for reciprocal movement in a travel path periodically passing over the marking and the underlying substrate. The heating method permits direct visual monitoring of the work site to achieve optimum adhesion of the marking to the asphalt or other substrate.

Method and apparatus for heating surface markings

A grinding assembly for grinding asphaltic pavement which attaches to a vehicle frame and includes a grinder and a grinder blade attached to the rear of the grinder. The lower edge of the blade extends down to a bottom of the grinder so as to contact unground pavement during operation. A brace assembly is affixed to the grinder and an adjustment brace coupling is affixed to the vehicle frame and is connectable to the brace assembly. The brace coupling is adjustable to pivot the grinder to change the elevation of the grinding surface relative to the lower edge of the blade.

Asphalt pavement grinder assembly

An asphaltic pavement preconditioning machine to remove and grind up old asphalt so that it can be rejuvenated. The method and apparatus heats a strip of asphalt, grinds a first strip portion and moves the ground asphalt to a second strip portion leaving behind an exposed unsoftened layer. Both the ground material and the previously heated unground asphalt in the second strip are then ground. The exposed hard asphalt in the first strip is heated, softened and then ground and moved onto the first strip portion. The heat from the ground asphalt lying over the center strip portion softens the unground asphalt there which is subsequently ground together with the ground material and left for further processing.
