A screed extension control system adapted for use on a screed assembly having a main screed, a main screed contact surface, a screed extension, and a screed extension contact surface. The screed extension control system comprises a slope actuator, a height actuator, at least one sensor, and a controller that is adapted to receive feedback from the at least one sensor. A virtual pivot point location is defined by a position where the main screed contact surface and the screed extension contact surface intersect. The controller causes at least one of the slope actuator and the height actuator to move between an extended position and a retracted position to control the position of the virtual pivot point location along the length of the main screed. A method for adjusting the screed extension position relative to the main screed.

A screed control system for a screed system includes a controller communicably coupled to a position sensor and at least one of a screed pressure assist system, an extendable screed height system, and a tamper system. The controller is configured to receive a signal indicative of a position of an at least one extendable screed with respect to a main screed. The controller is also configured to determine a change in the position of the at least one extendable screed with respect to the main screed. The controller is further configured to control at least one of the screed pressure assist system, the extendable screed height system, and the tamper system based, at least in part, on the determination.

A paving machine includes a machine frame, a drive assembly, including at least two tracks, each driven by a drive wheel and one or more idlers, and a paving material delivery assembly including a hopper, a conveyor assembly, an auger, and a screed. The paving machine also includes a tank of emulsion fluid, a spray bar positioned on an underside of the machine frame between the at least two tracks and fluidly coupled to the tank to deliver the emulsion fluid to a ground surface.

A road paver is provided with a drive, a bunker, a material conveying device, a screed comprising a tamping device and an electric heating device on the screed and/or on the tamping device, wherein a control unit is configured in such a manner that it determines, by means of a measurable electrical operating parameter of the electrical heating device on the screed and/or on the tamping device, the weight and/or the center of gravity and/or the width of the screed transversely to the working direction of the screed. A method for determining a width and/or a weight and/or a center of gravity of a screed of a road paver, comprising the steps: measuring an electrical variable of a heating device, in particular a heating power, a heating resistance or a power consumption of the heating device; calculating the weight and/or the center of gravity and/or the width of the screed transversely to the working direction of the screed by means of the electrical operating variable.

Methods and systems for making and using a wide swath offset concrete screed apparatus for screeding wet concrete slurry. The apparatus includes a cross support bar, an attachment mechanism for attaching the cross support bar to a liftable arm of a motorized vehicle, and lateral support bars for attaching a screed bar to the cross support bar. The screed bar is positioned offset from the motorized vehicle used to operate the screed, allowing the motorized vehicle to drive outside the forms.

Methods and systems for making and using a wide swath offset concrete screed apparatus for screeding wet concrete slurry. The apparatus includes a cross support bar, an attachment mechanism for attaching the cross support bar to a liftable arm of a motorized vehicle, and a roller screed attached to the cross support bar. The roller screed is positioned offset from the motorized vehicle used to operate the screed, allowing the motorized vehicle to drive outside the forms.

A hydraulic paver system for operating an electric paver in different operation modes including a first hydraulic circuit and a second hydraulic circuit, wherein the first hydraulic circuit includes a first hydraulic pump arrangement configured for providing a hydraulic driving power to driving device(s) for driving the electric paver, and the second hydraulic circuit includes a second hydraulic pump arrangement configured for providing hydraulic working power for working device(s) of the electric paver for paving, wherein the second hydraulic pump arrangement is driven in the paving mode for providing the hydraulic working power, and a control unit for operating the electric paver in the different operation modes, wherein in the transporting mode the first hydraulic circuit is activated and the second hydraulic circuit is deactivated, wherein the deactivated second hydraulic circuit provides a hydraulic standby power that is smaller than the hydraulic working power provided in the paving mode.

The present invention relates to an attachment screed unit for a road paver, comprising a connecting screed, at least one adjusting screed which is adjustably mounted on the connecting screed and which is adjustable between a retracted position (P.sub.1) and an extended position (P.sub.2), as a result of which the paving width (b.sub.4) of the attachment screed unit can be set in a variable manner, and a hydraulic adjusting device, which is arranged in such a manner that it can adjust the at least one adjusting screed between the retracted position (P.sub.1) and the extended position (P.sub.2), the adjusting device comprising an electro-hydraulic unit which is arranged on the attachment screed unit (10), and the electric hydraulic unit comprising a separate hydraulic circuit with at least one hydraulic pump and an actuator. The present invention further relates to a road paver with such an attachment screed unit.

The disclosure refers to a container for storing and providing at least one modular road paver assembly designed for detachable mounting on a road paver. The container comprises a storage system by means of which individual components of the road paver assembly can be positioned within the container in a standardized arrangement, such that the components of the road paver assembly can be checked for completeness by an operator by means of a visual inspection along a sequence determined between opposite boundaries of the container in view of their assembly sequence on the road paver.

The modular screed plate assembly and method has a road paver/finisher, a structural/conductor plate and modular screed plates. The road paver/finisher has a paver under side, a power source and a heating element, for heating the modular screed plates. The modular screed plates have coupling elements, and retainer quick-connect/releases, and align as a modular screed plate array, providing a tensionally yielding gap allowing the modular screed plate array to absorb pressures from paving operations. The structural/conductor plate couples with the coupling elements and has screed plate retaining locks to securely receives the retainer quick-connect/releases, in order to secure itself to the modular screed plates. The structural/conductor plate receives heat directly from the heating element, and provides indirect heat to the modular screed plate array.
