  • Patent number: 12006707
    Abstract: A machine for removing formwork from underneath a concrete slab includes a wheeled base movable on and supported at a support structure, a raisable and lowerable structure disposed on the wheeled base, and a formwork-removal device attached to the raisable and lowerable structure. The formwork-removal device includes (i) an arm extending from the raisable and lowerable structure and (ii) at least one pneumatic gripper disposed at a distal end of the arm. With the raisable and lowerable structure adjusted to position the pneumatic gripper under the formwork and engaged with the formwork, and when the pneumatic gripper is activated, the pneumatic gripper applies a suction to secure the formwork at the pneumatic gripper. With the formwork secured at the pneumatic gripper, and when the pneumatic gripper is lowered, the pneumatic gripper applies a separating force to the formwork to remove the formwork from the concrete slab.

  • Patent number: 9347187
    Abstract: A pavement repair system utilizes solid phase auto regenerative cohesion and homogenization by liquid asphalt oligopolymerization technologies. The system is suitable for use in repairing asphalt pavement, including pavement exhibiting a high degree of deterioration (as manifested in the presence of potholes, cracks, ruts, or the like) as well as pavement that has been subject to previous repair and may comprise a substantial amount of dirt and other debris (e.g., chipped road paint or other damaged or disturbed surfacing materials). A system utilizing homogenization by liquid asphalt oligopolymerization is suitable for rejuvenating or repairing aged asphalt, thereby improving properties of the paving material.

  • Patent number: 9121148
    Abstract: A system and apparatus for cutting grooves in a surface includes a housing having a rotatable cutting head mounted therein. An actuator drives the cutting head out of and into contact with the surface. Sensors disposed on the housing sense a depth of the groove cut by the cutting head. A controller is arranged to receive a signal from the sensors and compare the depth of the groove with a predetermined reference depth. The controller sends a signal to the actuator and adjusts the position of the cutting head via the actuator to maintain the depth of the groove at about the reference depth.

  • Patent number: 9068295
    Abstract: In a system for laying down an asphalt layer made of asphalt material, and having a road paver having a screed with compacting tools, a compacting device and a mixer, an electronic material density module is provided in or for the road paver. The electronic material density module obtains data during the laying process regarding at least the actual degree of compaction of the asphalt layer produced in the area of at least one compacting tool and evaluates and/or documents these data at least for operational optimisation and/or operational monitoring of the road paver and/or compacting device and/or mixer. The data obtained is communicated to the compacting device that produces the final degree of compaction of the asphalt layer based on the data and on the actual degree of compaction determined at the screed.

  • Patent number: 9062420
    Abstract: The invention relates to an unbalance type exciter (6) for a soil compaction device. This exciter comprises a carrying structure (5) as well as an unbalance weight (8, 9), which by means of a bearing (11a, 11b) is supported at the carrying structure (5) in rotatable manner around a rotation axis (Y) which in the intended use is stationary with respect to the carrying structure (5), for generating an intermittent exciting force for causing the carrying structure (5) in the intended use to vibrate. The bearing (11a, 11b) of the unbalance weight (8, 9) is arranged at least partially within the space which is circled by the unbalance weight (8, 9) when rotating around the rotation axis (y). Owing to the fact that this space is used for receiving at least part of the bearing of the unbalance weight (8, 9) it becomes possible to provide unbalance type exciters (6) having very small axial overall length.

  • Publication number: 20150147117
    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.
