  • Patent number: 11307124
    Abstract: An apparatus for testing paving samples includes a base that includes a paving sample tray about the cabinet and configured for translation relative to the cabinet. A roller is configured for imparting compressive forces to a sample carried by the sample tray. An arm is configured for moving the roller from a stowed position to an in-use position where the roller contacts the sample. A cylinder assembly having a piston therein supplies pressure forces to the arm to move the arm from the stowed position to the in-use position, wherein a depth of travel of the arm is limited by the sample. As the sample is compressed, the depth of travel increases. A measurement device is in communication with the cylinder for determining an amount of travel of the arm to thus determine an amount of compression of the sample.

    Abstract: A control system for positioning a marker over a pre-existing roadway surface mark. The control system has an electromagnetic radiation source attached to the marker for producing a mark pattern on the roadway surface. An imager permits the control system to image both the pre-existing roadway surface mark and the mark pattern produced by the electromagnetic radiation source. A computer is responsive to the imager for producing an error signal based upon the location difference between (a) the image of the pre-existing roadway surface mark and (b) the image of the mark pattern produced by the electromagnetic radiation source. An actuator is responsive to the error signal for positioning the marker over the pre-existing.

  • Patent number: 8961065
    Abstract: A method of milling asphalt is disclosed. The result of a survey of the unmilled asphalt pavement surface adjacent to the area to be milled is received. The result of the survey is stored in a computer memory. A map of the design surface specifying the design elevation of the milled surface over the area to be milled is stored in the computer memory. The relative elevation of the unmilled asphalt pavement surface adjacent to the area to be milled with respect to the machine body and rotatable milling drum of an asphalt milling machine is sensed. The elevation of the bottom surface of the rotatable milling drum is determined using a computer processor. The elevation of the milling machine body and the rotatable milling drum is automatically adjusted such that the milling drum mills the asphalt surface to the design elevation over the area to be milled.

  • Publication number: 20150016886
    Abstract: A machine engine idle speed control system may include an automated autoadaptive mode to supplement typical economy and normal power modes. The autoadaptive mode may afford an operator with an automated option to optimize fuel economy and lower engine/machine noise. The autoadaptive mode may initially default to a typical lower engine idle speed of the economy mode. However, as the machine workload rises, demands on the engine may become greater, and at a predetermined threshold of engine workload the engine idle speed may be automatically increased to a higher set point. The engine control may then remain at the higher idle speed until engine load is reduced to some predetermined target, and/or after a certain time period has elapsed. The time period may be controlled by a configurable delay timer to avoid unnecessary/undesirable cycling between modes. In addition, an operator may always intervene to increase or decrease engine idle speed.

  • Patent number: 8920070
    Abstract: A slipform paver includes a chassis 2 able to be adjusted in the heightwise direction and having a mounting unit 10 arranged on the chassis for fastening on an arrangement 8 for molding flowable material. The slipform paver is characterised in that the mounting unit 10 for fastening on the concrete mold 8 is mounted on the chassis 2 of the paver to be pivotable on an axis 14 extending in the direction of operation of the slipform paver. To produce parts of a structure whose orientation varies along their length, the concrete mold fastened 8 to the mounting unit is pivoted on the axis of pivot 14 by means of a pivoter unit 15 whereas the chassis of the paver maintains its orientation.
