Abstract: A device for spreading asphalt and other road paving materials is disclosed. The spreader comprises a main body, two separately adjustable wings and various end components to adapt the spreader to different road surfaces, tasks or operator preferences. Structural rigidity and strength results from the use of a three point hitch and a combination of three horizontal, longitudinally position pipes in the main body and three like positioned pipes attached to the wings, said pipes moving coaxially within the main body pipes.

Abstract: A material spreader system includes an elevated bridge for spanning a section of plastic concrete. A spreader including a hopper having an elongated rectangular slot is translated back and forth across the bridge to dispense a widthwise stream of topping material onto the underlying surface. Vibration generating elements are coupled at spaced apart intervals to the spreader hopper to provide for a uniform flow of topping material to the slot. A flow control device spans the length of the slot to dispense a continuous stream of topping material from the slot. A rotating metering device meters the flow of topping material through the slot. A motor translates the spreader back and forth across the bridge and rotates the rotating metering device as the spreader moves such that sequential translations of the spreader across the bridge followed by sequential translations of the bridge along the length of the plastic surface covers the entire surface with a uniform blanket of topping material.

Abstract: A pavement patching vehicle includes an asphalt supply hopper and a distribution hopper mounted to the front of the vehicle at the end of a remotely controlled articulated arm. Asphalt is deposited into a pothole from the distribution hopper for compaction by a tamper, which is mounted to the distribution hopper by a combination tamper positioner and vibration isolator. The combination uses a specially adapted gas over hydraulic liquid in a piston and cylinder arrangement for this purpose. The articulated segments are moved through piston and cylinder drives mounted within the hollow arm segments and coupled to pivot shafts at the joints. The distribution hopper can be secured to the front of the vehicle by a support bracket on the vehicle and a pivotal support latch on the distribution hopper. An actuator bar extends from the tamper and engages a latch actuator, which extends from the support latch, when the tamper is raised.

Abstract: An oil-spreading squeegee for roadway maintenance uniformly spreads oil sprayed onto a roadway surface to be maintained or upgraded. The squeegee assures a surprisingly uniform surface, particularly by filling cracks and moderate depressions in the roadway surface not filled by mere levelling of the liquid oil after a spraying operation alone. The squeegee is towed behind the oil spraying truck, extending across the roadway surface and being maintained on rollers a selected height above the existing pavement. The squeegee pools the oil ahead of its blade while forming a uniform coating on the roadway surface over which the blade has passed. The pool of oil fills cracks and moderate depressions in the roadway surface directly, and thus avoids loss of uniformity in the height of the top of the oil coating. Aggregate is then spread over the roadway and tamped or rolled into the oil, which hardens about the aggregate to form a new, smooth roadway surface.

Abstract: A material spreader for spreading a topping material over a wet concrete surface utilizes a pair of hoppers which are driven back and forth on a bridge support spanning the surface.

Abstract: For filling tracks worn in roadways, roadmaking material, preferably asphalt, is simultaneously laid in two adjacent tracks and in the intermediate strip of roadway, for which purpose the old material of the marginal regions of the tracks is replasticized as well as that of the intermediate strip; should the old surface of the intermediate strip be higher than the outer marginal regions of the two tracks, the replasticized material of the intermediate strip is removed to approximately the same level as the outer marginal regions of the two tracks, the removed material is laid in the tracks and, finally, the exposed surface of the intermediate strip is roughened before the new material is laid. Two stripping-laying apparatuses which are arranged at a distance from one another laterally of the working direction serve to fill the tracks and are connected together by a stripping element whose lower stripping edge is level with the front ends of the lower stripping edges of the stripping-layer apparatuses.
