The disclosure relates to a screed assembly for use at a road finisher. This comprises a control unit, a first compacting device and a second compacting device, which is arranged in a first direction behind the first compacting device. The disclosure is characterized in that the control unit is configured to activate and/or deactivate the second compacting device in a delayed manner relative to the first compacting device by a time period, which is unequal to zero. The disclosure furthermore related to a method for operating a screed assembly for use at a road finisher. This comprises the following steps: activating and/or deactivating a first compacting device of the screed assembly, activating and/or deactivating a second compacting device of the screed assembly, which is arranged in direction of travel of the road finisher behind the first compacting device, after expiration of a predeterminable time period, which is unequal to zero.

A bridge paving machine and method for paving a 3D design without vertical profile rails includes converting a desired design into a 3D surface model to account for certain factors known to cause deviations in the paving processes and paving the 3D surface model in the expectation that factors will cause the 3D surface model to deflect into the desired design. An on-board computer system adjusts the 3D surface model in real-time to correct for on-site variables. The on-board computer system receives data from various external sensors, including deflection sensors fixed to girders in the bride structure, and paving machine-based sensors, and uses various predictive models to predict surface deflection based on the sensor data. The 3D surface model is continuously updated based on the predictive models and actual measured deflections.

A work machine may include a frame supported by a traction device and a power activated steering guide secured to the frame. The power activated steering guide may include a trunk portion arranged and configured to articulate laterally relative to a travel direction of the work machine. The trunk portion may include an actuation mechanism configured to perform articulation and a controller configured for controlling the actuation mechanism to articular the trunk portion to an offset dimension.

A control station for a soil-processing machine includes a control station floor region and at least one floor window provided in the control station floor region. The floor window in the control station floor region is supported so that it can swivel between an open position and a closed position.

In some implementations, a control system may include at least one total station prism connected to a screed assembly of a paving machine, and a controller. The controller may be configured to obtain paving information that indicates locations of edges of a mat of paving material deposited by the paving machine. The paving information may indicate the locations of the edges based on data collected using the at least one total station prism. The controller may be configured to determine, based on the locations of the edges, an operating plan for one or more compactor machines that are to provide compaction of the mat. The controller may be configured to transmit, to another controller for the one or more compactor machines, plan information that indicates the operating plan.

Various embodiments for a median barrier finishing machine are described. A median barrier finishing machine may include a housing configured to encapsulate at least a portion of a median barrier, where the housing comprises a first vertical wall, a second vertical wall, and a horizontal wall. The median barrier finishing machine may include at least one adjustable member configured to couple the housing to the vehicle and retain the housing a predetermined distance relative to the vehicle while the vehicle is in motion. Further, the median barrier finishing machine may include at least one finishing device disposed within the housing, where the at least one finishing device is configured to contact a surface of a median barrier at least partially positioned within the housing and treat the surface as the vehicle moves the housing along a length of the median barrier.

A system and associated method constructs a building material from lunar soil. A magnetic sorter magnetically sorts the lunar soil and the system creates a layered surface comprising a microwave susceptible, thermal conductive top layer of lunar soil and a poorly microwave-susceptible and poorly thermally conductive sublayer of lunar soil. A microwave generator generates microwave energy into an antenna and directs the microwave energy onto the top layer of lunar soil to sinter the microwave susceptible, thermal conductive top layer of lunar soil.
