  • Patent number: 8950972
    Abstract: Provided herein are roadways containing polyurethane materials. A roadway includes a base layer of a compacted in situ material and/or a wear layer disposed on the base layer. One or both of these layers may include the polyurethane material to bind other components in the layers and to form more robust and durable roadway structures capable of withstanding operating loads of the roadway. In some embodiments, the polyurethane material is added to the wear layer by mixing in situ soil and/or foreign aggregate with polyurethane material or by dispensing the polyurethane material over the existing partially formed wear layer. The base layer may or may not include a polyurethane material. The type, concentration, distribution, and processing of the polyurethane material in the wear layer may be the same or different than that in the base layer.

  • Patent number: 8333333
    Abstract: A dust-control apparatus may be used in combination with tilling, cultivating, harvesting, construction machinery, and other mobile soil treatment implements. The apparatus applies mist to dust particles where the mist is created by pumping water or other liquid through nozzles. Because the apparatus is used in combination with the operation of the dust-generating machinery, the dust suppressing mist is applied nearly simultaneously to the generation of the dust by the agitation of the soil by the machinery. In one embodiment of the device, the operation of the pump or valves which control liquid flow to the nozzles is automatically activated by a optical sensor. The optical sensors cause either the starting of a pump or opening of a valve thereby increasing or decreasing the pressure and/or volume of the liquid upon the dust level reaching a preset trigger point as detected by the sensor.

    Abstract: A method of cold in-place recycling of asphalt to remediate distressed roads. Asphalt particles obtained by milling the existing asphalt are limited by screening to a maximum size of about one inch length. Asphalt particle size may be established by limiting tooth spacing of the road milling equipment milling head to about 5/16 inch or 8 millimeter spacing intervals. A predetermined proportion of portland cement, water, and asphalt emulsion are added to generate asphalt particles. Portland cement may be deposited onto the existing asphalt prior to milling. The resulting combination is mixed to generate a recycled mix, which may then be discharged onto the road being remediated and further processed, such as by screeding, compacting, and sealing.

More specifically, the instant invention is a road material reclamation device including a movable fame capable of being attached to another machine. At least one cylinder drive mechanism attached to the frame and configured to rotatably support a cylindrical rotary screen. The rotary screen has an interior, a front section and a rear section, a side rolling surface located adjacent the front section and the rear section, each side rolling surface being configured to engage the drive mechanism. Located adjacent the front section is a flange section. A cylindrical end frame supports at least one cylindrical end roller, the end frame and end roller being configured to engage the flange section and prevent axial displacement of the rotary screen. Additionally, a feed chute is located adjacent the rear section and is configured to direct material into the interior adjacent the rear section.

  • Patent number: 6626608
    Abstract: A mobile rock crusher for crushing raw rock material which has been windrowed on a roadway in the translation path of the crusher includes a rigid supporting structure, which includes a frame, and translation means for allowing translation of the frame over the roadway. A selectively actuable scoop is pivotally mounted to the frame for selectively actuable lowering over the roadway into sliding engagement with, so as to collect, the windrowed raw rock material onto the scoop. A first conveyor is mounted to the frame. An upstream loading end of the first conveyor cooperates with the scoop for conveying the raw rock material from the scoop onto a first screen at a downstream depositing end of the first conveyor. The first screen is for screening larger diameter material from smaller diameter material in the raw rock material so that the smaller diameter material falls through the first screen.

  • Patent number: 6565282
    Abstract: A tractor implement to grind surface pavement in removing paint lines is mounted on a tractor side and driven by a tractor power take-off. An implement first frame is supported rotatably on a rod extending orthogonally from the tractor. A rotatable tractor control mechanically connected to the implement first frame causes it to rotate on the rod, therein providing an implement adjustment in pitch and lifting and lowering the implement between a travel position and an operational position. The implement first frame connects pivotably to an implement second frame. A first hydraulic cylinder on the implement first frame parallel the rod connects to the implement second frame such that actuation of the first hydraulic cylinder causes the implement second frame to pivot about a second frame central axis therein providing the second frame an adjustment in roll. A grinding brush is mounted transversely to the implement second frame.

  • Patent number: 6439804
    Abstract: A method and apparatus for controlling the mixing of asphalt aggregate with rejuvenating materials in an asphalt rejuvenating machine. According to the method, milled aggregate is discharged in a windrow of fixed width, and windrow height is compared to rejuvenating machine speed to determine a volume rate of material being processed. A processor controller calculates a required amount of rejuvenating fluid addition based on the volume rate being processed and a desired proportion of rejuvenating fluid to aggregate. The processor controller controls a sprayer which directs rejuvenating fluid at some point along a zone extending from a milling apparatus to a mixer.
