Abstract
A method for applying contrasting thermoplastic markings to a roadway in a single pass. The contrast road marking apparatus includes two or more ribbon guns configured to apply a first thermoplastic marking to a roadway surface area and a second thermoplastic marking, which comprises a color that contrasts with a color of the first thermoplastic marking, to another roadway surface area. The resulting contrast road marking has no visible or substantially negligible overlap or gap between the individual thermoplastic markings.
Claims17
A method for applying thermoplastic markings to a roadway, comprising:
- aligning a second ribbon gun behind a first ribbon gun at a predefined distance;
- moving the first and second ribbon guns along a roadway;
- applying, with the first ribbon gun, a first thermoplastic marking to a first roadway surface area;
- and
- applying, with the second ribbon gun, a second thermoplastic marking to a second roadway surface area, the second roadway surface area being adjacent to and substantially mutually exclusive of the first roadway surface area.
A method for applying thermoplastic markings to a roadway, comprising:
- aligning a second ribbon gun behind a first ribbon gun at a predefined distance;
- moving the first and second ribbon guns along a roadway in a travel direction;
- applying, with the first ribbon gun, a first thermoplastic marking to a first roadway surface area;
- and
- applying, with the second ribbon gun, a second thermoplastic marking to a second roadway surface area, wherein the second roadway surface area is different than and adjacent to the first roadway surface area, wherein each of the first and second thermoplastic markings are elongated in the travel direction with right and left edges, the left edge of the first thermoplastic marking being substantially contiguous with the right edge of the second thermoplastic marking, or alternatively, the right edge of the first thermoplastic marking being substantially contiguous with the left edge of the second thermoplastic marking.
A method for applying thermoplastic markings to a roadway, comprising:
- moving the first and second ribbon guns along a roadway in a travel direction;
- applying, with the first ribbon gun, a first thermoplastic marking to a first roadway surface area;
- and
- applying, with the second ribbon gun, a second thermoplastic marking to a second roadway surface area, the second roadway surface area being adjacent to and substantially mutually exclusive of the first roadway surface area.
