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.

An adjustable width mold apparatus for a slipform paver includes a center portion and left and right sideform assemblies. The center portion has left and right lateral ends. Left and right telescoping support assemblies are connected between the sideform assemblies and the center portion. Laterally inner ends of the telescoping support assemblies are connected to the center portion laterally inward of the respective lateral ends of the center portion. One or more spacers may be received between each sideform assembly and the center portion to adjust the width of the mold apparatus.

A system, apparatus, and method can control one or more screed extensions or extenders of a paving machine. Such control can include identifying a location of an undesirable surface condition of a mat paved on a base by the paving machine using data from one or more sensors associated with a screed extension; characterizing the undesirable surface condition of the mat; and adjusting a height and/or an angle of attack of an extension plate of the screed extension to prevent future occurrences of the undesirable surface condition responsive to the identification and characterization of the undesirable surface condition. The location of the undesirable surface condition can represent a start of the undesirable surface condition in a transverse direction of the paving machine and can be associated with either an interface between the screed extension and a main screed or outward of the interface, along a length of the extension plate of the screed extension.

A linkage system for a screed extension includes a mounting plate that includes a mounting plate finger; an upper rail; a lower rail; a height adjustment shaft; a set of slide blocks that are disposed in a channel between the upper rail and the lower rail; a set of linkage arms; an angle of attack adjustment structure that holds the mounting plate finger at an angle; and a set of angle of attack adjustment screws. The height adjustment shaft is configured to adjust a position of the set of slide blocks within the channel and thereby adjust a height of a lower frame of the screed extension. The set of angle of attack adjustment screws are configured adjust the angle of the mounting plate finger and thereby adjust an angle of attack of the lower frame of the screed extension.

A system adjusts an instantaneous turn center for a paving machine having a tow vehicle and a screed assembly towed by the tow vehicle such that no portion of the screed assembly moves backward over freshly laid pavement when the paving machine paves around a curve. The system receives an input from an operator, a sensor, and/or a database. The input includes a distance and a direction from a first vertical axis defined by a traction device of the tow vehicle on a side of the tow vehicle facing the curve, to a second adjusted vertical axis defined by a point at least as far from the first vertical axis as an outer edge of the screed assembly that touches the curve. The system receives the input, and adjusts the instantaneous turn center for the paving machine to coincide with the second adjusted vertical axis.

The present disclosure refers to a paving screed for compacting a paving material, comprising at least one external control station for an operator for controlling at least one operating parameter adjustable on the screed, for example a power of a screed heating system. The external control station comprises a support and at least one operating panel detachably attached thereto as an input unit for the operator for setting the at least one operating parameter. The operating panel is attached to the support by means of a plug connection device having a first plug connector part with at least one first electrical contact part integrated thereon and a second plug connector part with at least one second electrical contact part integrated thereon. Furthermore, an electrical coupling of the two electrical contact parts integrated on the plug connector parts can be produced by a mechanical coupling of the two plug connector parts.

Screed plate assemblies, screed units, and pavers and methods for operating such assemblies, units, and pavers are disclosed. Example assemblies, units, and pavers include a screed plate assembly described herein. Such a screed plate assembly includes a screed plate, sensor(s) and actuator(s). Each sensor is mechanically coupled to the screed plate, and operative to sense a pressure on the screed plate and to communicate the sensed pressure. Each actuator is mechanically coupled to the screed plate, and operative to receive an input related to controlling an angle of attack (AoA) of the screed plate and to control the AoA of the screed plate based on the received input independent of controlling an AOA of another screed plate.

A step assembly may include a first step support member and a second step support member to be connected to a screed frame, and a step frame movably connected to the first step support member and the second step support member. The step frame may be movably connected to the first step support member by a first pin engaged with the first step support member and a slot of the step frame. The step frame may be movably connected to the second step support member by a second pin engaged with the second step support member and an aperture of the step frame. The step frame may be biased to a position relative the first step support member and the second step support member by a first biasing member and a second biasing member.

A screed assembly for a paving machine may comprise a main screed having a frame with a fixed width, and an extension screed slidably connected to the main screed and configured to extend laterally from the main screed to a fully-extended position. The extension screed may include a deflector, an inner plate proximate a central axis of the main screed, and an outer plate opposite the inner plate. At least one extender tube may extend between, and may be fixed to, the inner plate and outer plate. Each extender tube may have a shell comprised of a first material with a second material disposed therein, the second material offering increased stiffness to the extender tube so as to restrict flexion of the extender tube when the extension screed is in a fully-extended position.

A screw jack assembly includes a first body defining a longitudinal axis and a screw drive disposed within the first body. The screw jack assembly also includes a second body movable relative to the first body and coupled to the screw drive, and a first gear coupled to the screw drive. The screw jack assembly further includes a handle assembly having a tube member coupled to the first body. The handle assembly also includes a second gear coupled to the first gear. The handle assembly further includes a handle member coupled to the second gear and adapted to rotate about a rotational axis substantially perpendicular to the longitudinal axis. The handle member is adapted to selectively rotate between an operating position and a stowed position about the longitudinal axis based, at least in part, on rotation of the tube member relative to the first body along the longitudinal axis.
