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: 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.
