  • Patent number: 9822500
    Abstract: The invention pertains to pavement marking patterns and the application thereof to roads, streets, walkways and the like. Various pattern marking designs replicate bricks, cobblestones, horizontal signage, logos and other components. The marking patterns are composed of two or more independent sections, the first section is a grid representing for example, the mortar joints in a brick wall. The second sections or inserts, for example represent bricks which are contained within the grid. As the first and second sections are generally formed from different colored, preferably thermoplastic materials, a hot melt adhesive spray is utilized on the bottom surface of the marking pattern bridging the intersections between the first and second sections, maintaining the integrity of the marking pattern for convenience during handling and application to a substrate. Preferably the hot melt spray adhesive has approximately the same softening point range as the pattern sections for heat treatment during application.

  • Patent number: 9039321
    Abstract: An apparatus and method to install contraction joints in concrete slabs. The method uses a device, which inserts a strip of plastic or paper tape into freshly laced concrete, as the device is driven across a concrete slab. The tape is folded immediately prior to being inserted into freshly placed concrete, and functions to weaken the slab at the contraction joint location for the purpose of causing a crack to form in the slab. Plastic tape can be used, which functions as a moisture vapor retarder, and thereby, protects floor coverings from moisture damage, such as mold and mildew, at contraction joint locations.

  • Patent number: 9039323
    Abstract: A grinding attachment for highways and similar surfaces is disclosed for grinding operations closer to adjacent obstacles than is possible with existing equipment using a straddle-type centrally mounted grinding drum. The grinding attachment assembly comprises at one end a stub axle, which engages the grinding drum via a head extension. The stub axle is attached to a shroud which is in turn supported by a mounting assembly, which in operation attaches to a vehicle or machine able to drive the grinding attachment. The grinding drum can thereby operate proximal obstacles adjacent a grinding surface by virtue of arrangement of the stub axle, shroud and mounting assembly.

The means 14 for detecting the path followed by the milled edge co-operate with the arrangement 6 for steering the track-laying units 3A, 3B in such a way that the machine follows the path followed by the milled edge. The distance between the at least one reference point on the machine and the milled edge can be set in such a way that milled strips situated alongside one another are exactly aligned relative to one another.

  • Patent number: 7963719
    Abstract: A method and apparatus for applying various different coating on surfaces including but not limited to roadways, parking lots, bridge decks, airport runways, offshore heliports and workboat walkways. Preferably, an applicator is provided that allows numerous different coatings to be applied to a surface. The coatings may be protective, decorative, non-skid and/or reflective in nature. Preferably, the applicator allows for the dispensing of two or more materials in at least two different manners (e.g., (i) two or more materials simultaneously applied to the surface to be coated; and, (ii) one material applied followed by application of one or more additional materials). Preferably, the applicator is lightweight and compact so that a single individual can carry the applicator while applying a coating to a surface to be coated. This allows the applicator to be used to coat surfaces in constricted areas including but not limited to workboat walkways.

  • Patent number: 7866917
    Abstract: A device and method for marking pavement surfaces are provided. A trailer comprising an enclosure is adapted to mount a first guide bar supporting an electric motor. Multiple holding brackets are attached to the electric motor for keeping the electric motor on track of the first guide bar though multiple rollers. A metal block housing is supported on a second guide bar attached parallel to the first guide bar. A printer is mounted on the metal block housing and adapted for marking pavement surfaces. The printer comprises a primary reservoir for storing paint, multiple printing heads positioned at multiple openings on the metal block housing for marking the pavement surfaces, and a secondary reservoir for delivering paint to the printing heads through hoses. Multiple gears comprising a rack and a pinion allow the electric motor to control movement of the metal block housing with respect to the second guide bar.

  • Patent number: 7845878
    Abstract: A smoothness indicator for measuring a profile of a road surface includes two or more non-contact elevation distance sensors, such as ultrasonic sensors, laser sensors, or the like. The non-contact elevation distance sensors are arranged in pairs including a trailing non-contact elevation distance sensor and a leading non-contact elevation distance sensor disposed at a known distance from the trailing non-contact elevation distance sensor along the profile. A slope sensor for measuring an angle of incidence of the leading and trailing non-contact elevation distance sensors relative to a horizontal plane is also included. The smoothness indicator generates an elevation profile of the road surface by calculating an elevation for the second location using an elevation assigned to the first location and an elevation difference between the first location and the second location.

  • Patent number: 7806626
    Abstract: Disclosed herein is a system and method for computer assisted driving of vehicles. The system disclosed herein provides an array of sensors positioned in the vehicles at strategic points for capturing vibrations and sound induced, when the vehicles move over pavement surfaces marked with predefined patterns of peaks and troughs. The sensors further measure frequencies of these vibrations. An onboard computer on the vehicle matches the captured frequencies and sound against pre-specified frequencies to obtain unique frequency signatures for the segment of the pavement traversed by the vehicle. Navigational data and geographical data associated with the unique frequency signature are used to provide assistance in driving of vehicles.
