Abstract
A contrast road marking apparatus can apply 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 location and a second thermoplastic marking, which comprises a color that contrasts with a color of the first thermoplastic marking, to another roadway location. The resulting contrast road marking has no visible or substantially negligible overlap or gap between the individual thermoplastic markings.
Claims15
An apparatus for applying thermoplastic markings to a roadway, the apparatus comprising:
- a first ribbon gun configured to apply a first thermoplastic marking;
- a second ribbon gun configured to apply a second thermoplastic marking, the first thermoplastic marking having a first color that contrasts with a second color of the second thermoplastic marking;
- means for orienting the first ribbon gun so that the first thermoplastic marking is applied onto the roadway at a first roadway surface area;
- means for orienting the second ribbon gun so that the second thermoplastic marking is applied onto the roadway at a second roadway surface area, the second roadway surface area being adjacent to and substantially mutually exclusive of the first roadway surface area;
- and
- means for moving the apparatus along the roadway.
An apparatus for moving along a roadway and applying thermoplastic markings to the roadway, the apparatus comprising:
- a first ribbon gun configured to apply a first thermoplastic marking at a first roadway surface area;
- and
- a second ribbon gun configured to apply a second thermoplastic marking at a second roadway surface area, the second roadway surface area being different than and adjacent to the first roadway surface area;
- wherein each of the first and second thermoplastic surface areas are elongated in the travel direction with right and left edges, the left edge of the first thermoplastic surface area being substantially contiguous with the right edge of the second thermoplastic marking, or alternatively, the right edge of the first thermoplastic surface area being substantially contiguous with the left edge of the second thermoplastic marking.
