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.

A hot applied thermoplastic pavement composition and method of using is described wherein the composition comprises; a modified polyamide resin in the range of between 3 and 10 percent by weight, wherein the composition contains rosin-modified esters, a copolymer, 30-70 percent by weight of a glass bead intermix, a range of between 1 and 15 percent by weight of either white or yellow pigment, the balance of the composition being selected from the group consisting of; one or more plasticizers, inorganic fillers, waxes, antioxidants and light stabilizers.

Disclosed herein are an apparatus and method for applying a magnetic pattern to lanes with magnetic paint. The apparatus includes an electromagnet for generating a write magnetic field toward the ground by being installed in a moving object, a current supplier for providing the current required to generate the write magnetic field, a portable power generator for supplying power required in order for the current supplier to generate the current, and a cooler for dissipating heat generated from at least one of the electromagnet and the current supplier.

A ground marking apparatus is configured to apply marking material to a ground surface. The ground marking apparatus includes a beam supported by a beam mount and extending along a beam axis. A carriage is disposed on the beam and movable on the beam along the beam axis. A carriage motor operably interfaces with the beam and is configured to move the carriage along the beam. A dispense arm is supported by the carriage and is configured to move relative to the beam as the carriage moves along the beam.

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.

Disclosed are various embodiments for a contrast road marking apparatus and 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.

Trafficked pavement substrates utilize markings to segregate traffic (e.g., divide lanes traveling in the same direction, divide sides of the road traveling in opposite directions). A dry polymer modified cement mixture may be used to provide the markings. The dry polymer modified cement mixture is prepared by mixing a dry polymer modified cement blend (ordinary Portland cement, aggregate and polymer powders) with water. The location of the lines is identified, and the dry polymer modified cement mixture is applied onto the identified areas as a thin layer. The dry polymer modified cement blend may include polymers to provide colored markings. Glass beads may be embedded into the dry polymer modified mixture before it cures to retroreflect light shined thereon. The trafficked pavement substrate may have troughs formed therein and the dry polymer modified cement markings may be formed therewithin so that the markings are flush.

A system and method (i.e., utilities) for calculating, in substantially real-time, the thickness of marking materials applied to roadway surfaces. The utilities utilize a linear position sensor to monitor positions of a shaft of a positive displacement paint pump. By monitoring the shaft position multiple times per stroke of the pump, pump displacement volumes may be calculated for intra-stroke movements of the pump. The pump displacement volumes permit calculating applied thickness of the marking materials in finer temporal increments than was previously possible.
