  • Patent number: 10184048
    Abstract: A system for dispensing a fast curing epoxy traffic marking composition to a transportation corridor includes a plurality of bins positioned on a transportation corridor marking dispensing apparatus. A first bin contains an epoxy coating which is applied by the dispensing apparatus on a transportation corridor. A second bin contains at least one curing agent which is coated on a carrier such as glass beads or porous silica. These carriers are dropped onto the epoxy coating by the dispensing apparatus and promote rapid curing of the top layer of the epoxy coating while the bottom layer is given additional time to adhere to the roadway surface. This enables the application contractor to open a marked roadway in a quicker manner with less motorist disruption. An optional third bin contains retroreflective beads which are applied to the epoxy coating by the dispenser apparatus to improve visibility of the line marking.

  • Patent number: 8308394
    Abstract: Embodiments of the present invention relate to systems and methods implemented in a pothole patching system for creating a vacuum that pulls heavy particulate, such as gravel, out of a hopper. For example, according to an embodiment, a vacuum body having a vacuum chamber formed therein is positioned proximate to an opening of the hopper. A moveable slide gate is provided between the vacuum chamber and the opening of the hopper. The slide gate moves between open and closed positions for permitting and blocking communication between the vacuum chamber and the hopper. A reduction nozzle is provided between an air source and the vacuum chamber. Forced air flows from the air source, through the reduction nozzle, and into the vacuum chamber. The reduction nozzle reduces the pressure of the forced air entering the vacuum chamber, and thereby creates a vacuum in the vacuum chamber. When the slide gate is in the open position, this vacuum pulls particulate from the hopper.

  • Patent number: 7448826
    Abstract: A device for simultaneously spreading cut fibers and binders on a roadway width, includes, in the longitudinal direction, a first binder spreading set, a second cut fiber spreading set and a third binder spreading set, the second set including cutting tools, which are driven by a torque transmission member. The device is modular, the modules being transversally arranged side by side and each allowing to spread on a longitudinal lane of the roadway binders and cut fibers. Each module has a first nozzle, a tool for pulling and cutting continuous fibers and throwing cut fibers to the roadway, a second nozzle, the nozzles being connected to a common binder dispensing member. Each tool is removably mounted in its module between a working position where it is in the module and driven by the driving shaft and a releasing position where it is available to an operator and at rest.

    Abstract: An apparatus or a vehicle for applying multiple coatings of fluid to a surface in a single moving pass comprises a manifold having a plurality of nozzles. A first nozzle applies a first layer of fluid to the surface in accordance with a first spray pattern. A second nozzle carried applies a second layer of fluid to the surface in accordance with a second spray pattern. The second layer substantially covers the first layer. A third nozzle applies a third layer of fluid to the surface in accordance with a third spray pattern. The third layer substantially covers the first and second layers. The apparatus provides for multiple coatings of one or more fluids onto a substrate in a single pass, whereby the application of the various layers is accurately controlled to achieve a desired result.

  • Patent number: 7134806
    Abstract: A method of repairing a road surface includes providing a hopper mounted on a spreading vehicle and means to spread material carried in the hopper over depressed areas of the road surface to fill them with the material. At ambient temperature, a batch of patching slurry is mixed comprising aggregate, asphalt emulsion, water, Portland cement, and a retarding agent operative to increase a break time of the patching slurry, and the batch is deposited into the hopper. The spreading vehicle is maneuvered to spread the patching slurry successively over a plurality of depressed areas until the hopper is empty. The ingredients of the patching slurry are adjusted to provide a patching slurry having a break time sufficiently long to allow the hopper to be emptied before the patching slurry begins to set, and sufficiently short to allow traffic to pass over a filled depressed area within a desired time.
