Abstract: Apparatus is described for obtaining uniform compaction of asphalt concrete to reduce or prevent cracking of the asphalt concrete surface. A mobile confinement edge force is maintained in contact with the edge surface of an asphalt concrete mat while the mat is being compacted. This is performed in a manner such that the density of the mat across the full width of the mat becomes uniform. By obtaining uniform density of each lane of the mat as it is laid significantly reduces the incidence of joint cracking and deterioration of the asphalt concrete, in the longitudinal joint area, over time.

Abstract: A tracer head for a copy milling machine which is digitally controlled and causes a model to be scanned by a stylus mechanically mounted in the tracer head. The stylus is deflected both at right angles and tangentially to the surface of the model when the stylus contacts the model to produce scanning signals which are proportional to the deflections at right angles to the model surface and the deflections tangential to the model surface. These signals then are transmitted to a processor which processes, amplifies and subsequently feeds the processed and amplified scanning signals to servomotors of the machine to cut and shape a workpiece in such manner as to produce a copy of the model. The amount of spring pressure exerted on the stylus inside the head by the mechanical spring mounting when the stylus contacts the model is determined by establishing the pressure separately along each of the three mutually orthogonal x, y and z axes.

Abstract: PCT No. PCT/US79/00495 Sec. 371 Date July 11, 1979 Sec. 102(e) Date July 11, 1979 PCT Filed July 11, 1979A compacting apparatus (10) has an impact apparatus (17) and a compactor (19). The impact apparatus (17), such as, for example, a rock breaker, provides impacting forces on the compactor (19). The compacting apparatus (10) is positioned on, for example, a work structure (12,14,15) of a work vehicle (16). It is necessary to compact material in order to provide, for example, proper filling of a trench (74) after a pipe has been placed in the trench. Compaction, as done by the compacting apparatus (10), is provided by simultaneously compacting the material and applying a compressive force to the material and remolding the material. Therefore, satisfactory compaction can be provided in the trench (74) by the work vehicle (16) which is also usable to excavate and refill the trench (74).
Abstract: A two-to-one or greater slope is stabilized by rolling a vibratory compactor upslope and simultaneously vibrating the compactor's roller. The compactor comprises a frame on which is rotatably mounted a suitable compaction roller. An engine is rotatably mounted on the frame, and means are provided for adjusting the tilt of the engine relative to the frame, so that, in use, the engine will remain upright while driving the vibratory shaft of the roller. The engine is remotely controlled, as by radio waves, by an operator riding a vehicle on the shoulder of the embankment. A crane and winch on the vehicle riding on the embankment control the movements of the compactor on the slope.
Abstract: An earthen structure for holding back a body of water has a sloped surface which is paved with an overlapping arrangement of strips constructed of castable material. Each strip is formed by conveying castable material from a mobile receiving hopper that is propelled adjacent to the base of the earthen structure. A bridge conveyor projects laterally from the receiving hopper over the slope. The bridge conveyor deposits the castable material onto the slope forwardly of a spreader device that is advanced longitudinally relative to the slope by a prime mover. A scraper blade of the spreader device is positioned at a preselected elevation by a forwardly projecting sidewall which is connected to the blade and slidable on a previously formed strip. The sidewall maintains the castable material in front of the blade, as the advancing blade spreads the material in a longitudinal strip of a preselected thickness and having a lateral edge extending a preselected lateral dimension outwardly from the sloped surface.
Abstract: A method for loosening stony soil by means of a rotating cutting head fastened to the rear of a tractor and having cutting members to be drawn through the soil and being mounted according to a helical line.Stony soil can be readily loosened to the desired depth because the cutting head can be kept at an acute angle to the direction of movement. So the cutting head is drawn in a stable manner in the direction to the tractor against the stone surface concerned and penetrates the stony soil like a plough, the soil above the cutting head being torn up upwardly.
Abstract: An earth working apparatus is disclosed including means for removably coupling a compacting roller into operative engagement with a hydraulically manipulated boom while simultaneously maintaining the excavating bucket of the apparatus in its operative association with the boom.

Abstract: A dirt compacting and asphalt compacting roller unit of sufficient weight for utilization in compacting fill dirt introduced into a ditch to fill the ditch, and for utilization in compacting hot asphalt subsequently applied over the previously compacted fill dirt. The roller unit comprises a smooth-surface circumference drum shape roller with concentrically positioned shaft protruding laterally on each side. The roller has two or more detachable dirt compacting plates having multiple exteriorly projecting protrusions which, when the plates are attached to the roller, become the exterior circumference of the roller and act to compact fill dirt when the roller with plates attached is repeatedly rolled over fill dirt within a ditch. When the plates are detached, the smooth-surface circumference of the roller acts to compact hot asphalt when the roller's smooth-surface circumference is repeatedly rolled over hot asphalt subsequently applied over the previously compacted fill dirt.
