Thermochromatic temperature marking for outdoor surfaces

A roadway marker with a thermochromatic adhesive backed sheeting comprising;

• at least two preformed thermoplastic segments of said sheeting that includes top sides and bottom sides with an adhesive layer on said bottom sides of said thermoplastic segments;
• and;
• a protective sheet covering said adhesive layer on said bottom sides;
• wherein said bottom sides and said protective sheets covering said adhesive layer of said bottom sides may be subsequently adhered to any suitable outdoor surface using at least pressure to provide adequate bond strength to ensure a proper permanent or semi-permanent or temporary surface covering said suitable outdoor surface and wherein the chemical composition of said adhesive is alkyl or butyl-based and wherein said top side is a thermochromatic, color indicative sheet or device that is bonded to a concrete or asphalt surface, a traffic sign, or a plate of a guidepost and upon which is indicated a surface temperature
• and;
• a protective sheet for pressure sensitive adhesive only that covers said adhesive layer on said bottom sides.

A method for providing a thermochromatic adhesive backed sheeting comprising;

• providing at least two preformed thermoplastic segments of said sheeting that includes top sides and bottom sides with an adhesive layer on said bottom sides of said thermoplastic segments;
• and;
• a protective sheet covering said adhesive layer on said bottom sides;
• wherein said bottom sides and said protective sheets covering said adhesive layer of said bottom sides may be subsequently adhered to any suitable outdoor surface using at least pressure to provide adequate bond strength to ensure a proper permanent or semi-permanent or temporary surface covering said suitable outdoor surface and wherein the chemical composition of said adhesive is alkyl or butyl-based and wherein said top side is a thermochromatic, color indicative sheet or device that is bonded to a concrete or asphalt surface, a traffic sign, or a plate of a guidepost and upon which is indicated a surface temperature.
