A diamond trowel blade 20 comprises diamond particles that will attach to a power trowel for surface preparation of hardened concrete surfaces. The diamond trowel blade includes a diamond bearing surface 22, for preparing the concrete surface; a backing plate 24 for supporting the diamond bearing surface; and a mounting arm 26 for attaching the trowel blade 20 to the power trowel. A method for mechanically preparing a concrete surface with a diamond trowel blade 20 attached to a power trowel inc...
A method for reducing tire to road noise generated by vehicles on a road surface comprises generating a pseudorandom unique line pattern, providing said pattern as transverse grooves disposed in the road surface, said grooves being randomized according said line pattern as to one or more of position, frequency, and depth so as to spread the noise spectrum thereby reducing the amplitude or volume of noise generated at any single frequency and are capable of dramatic reductions in noise generated ...
A device for preparing a sloped mud surface around a drain prior to setting tile or stone includes one or more arms (i.e., rigid arms) attached to a sleeve and rotatably supported relative to a vertical axis defined by a vertical shaft and horizontal planar base. An adjustable clamp assembly releasably secures the device to a conventional drain, which may be secured to a drainpipe by pipe threads. The bottom edge of the arm provides a straight working edge. The arm can be freely moved (i.e., rot...
A scraper apparatus including a cart and a scraping arrangement located at a front of the cart. The scraping arrangement includes blades that are driven along a joint or crack by the cart to remove excess filling material deposited in the joint or crack of a working surface.
A method and apparatus for heating hot mix asphalt (HMA), via collecting fumes from HMA while the HMA is on-board a vehicle and in motion within the vehicle, and igniting the HMA with engine exhaust and using the heat of combustion of the HMA to heat HMA, such as via the floor of a re-mix machine or paver which is capable of churning and mixing the HMA which increases emission of HMA fumes.
At a milling machine to work ground surfaces, with a machine frame, a milling drum supported at the machine frame, at least one transport device arranged at the machine frame which accepts the milled material from the milling drum, as well as with a suction device for the air polluted with dusts and vapors, whereby the milled material on the at least one transport device is enclosed by a channel, the suction device is connected to a rear channel section of the channel in the direction of the mat...
A vibratory concrete screed includes a vibration isolation system that minimizes the transmission of vibrations to the operator under normal operating conditions, but becomes more rigid during screed control forces applied to the blade through the isolation system when the operator applies greater forces to the operator handle. The system includes low durometer elastomer vibration isolators isolating the operator handle from the vibration exciter and screed blade in a manner that limits vertical...
A screed assembly includes a screed plate, a console assembly, and a first and second handles. The various components of the screed assembly are attached to one another with quick connect mechanisms so that they can be disassembled for cleaning and transport and reassembled at a new site. A tilt mechanism operated by a horizontal beam of light can also be utilized and is also attached by a quick connect mechanism.
A method of making a membrane assembly by forming at least a pair of bottom sheet membranes and at least one top sheet membrane, wherein the bottom sheet membranes are adapted to attach to and cover respective pavement sections of a roadway, and constructing each top sheet membrane with a track, wherein each track receives edges of a corresponding pair of the bottom sheet membranes.
A method of reconstructing a road is provided. This method includes taking representative cores of the road, analyzing the cores, selecting a substantially solvent-free emulsion based on climate history, mixing the emulsion and reclaimed asphalt pavement particles to form an asphalt emulsion mix, testing the asphalt emulsion mix for performance using a raveling test, a thermal cracking prediction test by an indirect tensile testing, a moisture susceptibility test utilizing vacuum saturation, and...
