The screed plate apparatus and method has a road paver/finisher, screed plate, and material matting apparatus having a power source and structural/conductor plate. Paving material is loaded into the material matting apparatus and applied homogeneously as a paving mat to a road surface in a road paver/finisher travel direction. The structural/conductor plate is attached to the road paver/finisher and to the screed plate to provide indirect heat to the screed plate. The screed plate bottom side has differing forms of textured surface impacting the paving material, by differing corrugations of differing patterns, into a more homogeneous consistency. The corrugated pattern may be oriented parallel or perpendicular to the paver travel direction, and/or progressively flattening or set in a crisscross rhombic pattern. A vibrating and oscillating mechanism operates horizontally and vertically upon the screed plate providing a homogeneously sorting on the paving material.

A vibrating screed includes a power unit, a plurality of screed blades, wherein each of the plurality of screed blades is removably engageable with the power unit one at a time. The vibrating screed further includes a power unit controller operably coupled to the power unit, a memory operably coupled to the power unit controller, and a blade selector operably coupled to the power unit controller. The power unit controller is operable to receive a blade selection from the blade selector, the blade selection indicating a size of a particular screed blade within the plurality of screed blades; retrieve a range of operating speeds associated with the blade selection; and set the operational speed of the vibrating screed to correspond to the range of operating speeds associated with the blade selection.

An apparatus for screeding concrete to produce a level finished surface includes a frame assembly having an integral screed head having at least one member for contacting said concrete, a leveling assembly secured to the frame assembly having a plurality of vertically adjustable leveling legs capable of extension and retraction and a plurality of wheels secured to the leveling legs, each capable of rotation around a vertical axis for steering.

A screed assembly includes an auger, a cylinder, and a vibratory screed. The screed assembly may be included in an undercarriage. The undercarriage may be coupled to a carriage. The carriage may travel along a length of a framework. One or more sensors may be used to determine height information of the screed assembly relative to a surface to be paved. One or more actuators may be used to selectively adjust the height of the screed assembly based on the height information.

A paving machine includes a mold coupled to a telescopic frame member, by which the mold side-shifts relative to a main frame. A tight clearance between the paving machine and a surface being paved may be achieved by the ability to side-shift the mold. The paving machine may also include a number of vibrator motors. A flow to the vibrator motors may be controllable by a manifold controller. The manifold controller is located on an end of the telescopic frame member. By locating the manifold controller on the telescopic frame member, an operator of the paving machine may both stand on the telescopic frame member to watch the paving mold and adjust the settings of the vibrator controller. This is advantageous in allowing the operator to achieve proper concrete consolidation by visual feedback without leaving the telescopic frame member.

A support structure for a float pan for floating a concrete surface provides an interface between the float pan and a rotating machine. The support structure is characterized by a hub configured for concentric attachment to a rotor, and by trusses that extend radially from the hub, each providing a float pan contact surface and means for attachment to the float pan. Perimetric bracing links the trusses about the perimeter of the support structure. A machine similar to a walk-behind or ride-on trowel but without rotor blades, may incorporate the support structure and operate as a dedicated power flotation machine. Under weight of the machine, the contact surfaces of the trusses conform the float pan to a desired shape or radius of curvature for optimizing a flotation process.

A device is provided for monitoring the compaction of concrete introduced into a slipform of a slipform paver by means of at least one concrete compacting device that has an asynchronous motor for driving an unbalanced mass which generates vibrations. The monitoring device comprises an apparatus for monitoring the stator current of the asynchronous motor, the apparatus being configured such that a change in the compaction of the concrete is determined based on an analysis of the stator current. The apparatus for monitoring the stator current of the asynchronous motor is preferably configured such that the amplitude spectrum of the stator current is determined in order to analyse the stator current. It is advantageous that the compaction of the concrete is not monitored using sensors which are exposed to harsh ambient conditions during operation of the slipform paver.

Methods for controlling the traveling operation of a self-propelled ground compaction machine with the aid of a control unit which provides travel control signals to a travel drive system of the ground compaction machine. The ground compaction machine may alternatively be operated in an operator mode in which travel specifications specified by an operator via a manually operable input device are transmitted to the control unit and are transmitted by the latter in the form of travel control signals to the travel drive system of the ground compaction machine. A ground compaction machine, in particular a vibratory plate or a trench roller.
