A screed assembly for a paving machine includes a main screed unit having a first section and a second section. A hinge assembly located above the main screed unit pivotally couples the first section with the second section. The first section and the second section rotate around a horizontal axis passing through the hinge assembly. A seal member located between the hinge assembly and the main screed unit covers a gap defined between the first section and the second section below the hinge assembly such that the seal member covers the gap and laterally extends beyond the gap above the first section and the second section. A pair of heating components attached to the first section and the second section heats the first section and the second section.

A road paver comprises a tractor vehicle with a material hopper for receiving paving material and a paving screed for compacting paving material. The paving screed comprises at least one electric heating device for heating the paving screed. The road paver comprises at least one electric switching assembly configured to switch an electric power supply of the electric heating device. The electric switching assembly comprises an electric parallel circuit of two switching devices, wherein the electric parallel circuit of the two switching devices forms a series electric circuit with the electric heating device.

The present invention relates to a road paver 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 provided, which 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. The present invention further relates to 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.

A screed arrangement for a paver machine includes a screed body including a deflector member and a base plate, and an oscillating tamper bar arrangement positioned between the deflector member and the base plate. The screed arrangement further includes a connecting element connecting the oscillating tamper bar arrangement and the screed body to each other.

A construction machine for building or finishing a road, such as a road finisher, comprises at least a working equipment, a display unit and a plurality of sensors. Each sensor is adapted to measure a value of an operating parameter of the construction machine. The sensors are adapted to output data corresponding to the measured values to the display unit, and the display unit is adapted to output a representation of at least a part of the construction machine together with the measured values of the operating parameters.

A compaction compensation system comprising a mechanism for automatically height adjusting the height adjustable mounting (30) so as to height adjust the sensor relative to the screed by a compaction compensating factor. It is used in a paving machine (1) for laying compactable paving material, the paving machine comprising: (a) a height adjustable screed (5) for laying a layer of compactable paving material onto a surface; (b) a sensor (15,17) for sensing the height of the screed relative to a reference level, the sensor being attached to the screed by a height adjustable mounting; (c) a screed height control system for automatically adjusting the height of the screed in response to different heights sensed by the sensor due to contours of the surface, so as to adjust the screed to lay a layer of varying thickness.

A method may include determining, by a controller of a paving machine, to start a test of one or more heaters associated with a screed assembly of the paving machine. The method may further include sending, by the controller and to a tester device associated with the paving machine, one or more signals configured to cause a test voltage to be generated while the one or more heaters are sequentially turned off and then on during the test. The method may further include receiving, by the controller, a measurement of an insulation resistance of each of the one or more heaters during the test. The method may further include performing, by the controller, one or more actions based on a result of processing the measurement.

A method includes receiving first information indicative of a first selection of a machine disposed at a worksite, wherein the first information is received from an electronic device disposed remote from the worksite. The method also includes receiving second information from the electronic device, wherein the second information is indicative of a second selection of a component of the machine. The method further includes determining, using at least one sensor, that an area surrounding the machine is free from unknown objects, and receiving third information indicative of a request to activate the component. The method also includes causing activation of the component based at least in part on the third information.

A method for heating a screed of a road finishing machine, the method including obtaining a predetermined time for putting the screed into operation; obtaining a start time for beginning the heating of the screed based on the predetermined time; and automatically heating the screed by energy supply to a heating means of the screed from an energy source from the start time.

Insulating means to be used with a screed for a road finishing machine comprises at least one insulating element and one connection element for a releasable connection with the screed. The insulating element is designed to cause, in a state of the insulating means connected with the screed, a reduced emission of heat from the screed through the insulating element.
