Abstract: Method for laying down a pavement with a road paver, in which machine parameters are coordinated at least with paving requirements of the pavement by means of a controller and in which at least one machine parameter set is created and stored in advance for a paving requirement determined before the paving, the parameter set allowing a high level of machine efficiency and pavement quality to be expected and/or has already produced the same for an at least similar earlier paving requirement of an already laid down pavement, and the pavement on the basis of the parameter set created in advance. The road paver has a controller with an on-board computer connected to a sensor system and an actuating system, and includes memories and a retrieval and/or comparison section for triggering the actuating system for implementing the machine parameters of the parameter set created in advance.

Abstract: An external control stand for a self-propelled construction machine. The construction machine has a working component that can be operated from the external control stand. The invention includes a lighting device for illuminating a ground section on the external control stand, as seen in the direction of travel, in front of, behind and/or below the external control stand.

Abstract: The invention relates to a construction machine, in particular a road finishing machine, which can be set to at least two different operating modes by the operator. With a control system, a determined position for a drive can be stored in a first operating mode to which the drive automatically moves during a change from a second operating mode back to the first operating mode. In case of a change of the operating mode from the second operating mode to the first operating mode, several drives can optionally also be simultaneously moved to the previously stored position.

Abstract: The invention relates to a charging vehicle (1) for conveying road-surfacing mix to a road-finishing machine, wherein the charging vehicle (1) comprises a conveyor assembly (5) and a machine drive (6). The invention is characterized in that the machine drive (6) is arranged on the charging vehicle (1) laterally offset with respect to the conveyor assembly device (5).

Abstract: A method of laying a finishing layer with a road finisher F having a screed B, whereby the screed, equipped with a tamper device T and a smoothing plate, at least compacts and superficially smoothes the finishing layer, and the stroke and/or the frequency of the tamper device T are remotely varied for laying a finishing layer with a paving thickness and/or laying rate V which vary over the pave width and transversely to the working direction R within the pave width. A road finisher having a screed suitable for implementing the method set forth above wherein the road finisher or screed has an adjustment device for the remotely actuated local variation of at least the stroke of the tamper device within the pave width.

Abstract: A road construction machine, particularly a road finisher or a feeder for a road finisher, with a primary drive unit including at least one combustion engine driving a three-phase generator, and further including at least one connection means for at least one conventional alternating current standard consumer, at least one stabilized voltage supply unit is connected between the connection means and the three-phase generator, wherein the voltage supply unit provides standard mains voltage with a permanently stable frequency at the connection means independent of the speed of the combustion engine driving the three-phase generator.

Abstract: A system for controlling construction site vehicles has a plurality of construction site vehicles and a control room. Data can be transmitted on communication channels between the control room and the construction site vehicles. In the control room, at least one digital map is stored in which at least one additional piece of information is stored for individual road sections, in addition to the route of the respective road section. A navigation module is provided and designed to generate, with reference to the at least one digital map, navigation recommendations for the construction site vehicles.

Abstract: A road paver with a layer thickness measuring device which comprises a plurality of sensors in order to measure a distance to the subgrade or to the road pavement. The layer thickness measuring device is mounted rotatably on the road paver or on its screed, whereby the layer thickness measuring device has an equilibrium position at a stipulated angle to the horizontal that it retains or to which it returns even if the inclination of the road paver or of the screed to the horizontal changes.

Abstract: A road paver with a movable screed and with a layer thickness measuring device, which includes at least two sensors. The sensors are formed to carry out a distance measurement to the paving plane at intervals to determine a distance between the sensor and a point on the surface of the plane, said point being registered by the sensor. One of the two sensors defines a coordinate system. The layer thickness measuring device is formed to add as vectors the distance to the plane measured by the sensor that defines the coordinate system and a movement, relative to the plane and resulting from the driving of the road paver, of the coordinate system that is defined by the one sensor. In this way, a first vector can be determined which, together with a second vector, is used by the measuring device for determining the layer thickness of the laying material.

Abstract: The invention relates to a screed arrangement for a road finisher with a basic screed and two extending screeds arranged in front of the basic screed in the laying direction of travel of the road finisher and movable transversely to the laying direction of travel relative to the basic screed. A deflection member is fitted to the basic screed and/or to at least one of the extending screeds and is movable relative to it.
