A paving system includes a paving machine, including a hopper, a conveyor, an auger, a screed assembly, and one or more tracks. The paving system also includes one or more obstacle detection elements positioned on the paving machine. The paving system further includes a controller in communication with the one or more obstacle detection elements and one or more of the conveyor, the auger, the screed assembly, and the one or more tracks. The controller is configured to receive information from the one or more obstacle detection elements, and control one or more of a width of the screed assembly, an angle of attack of the screed assembly, a height of the screed assembly, an angle of the screed assembly, or a speed of the paving machine in order to maintain a desired height of paving material delivered to a ground surface by the paving machine.

A paving machine for wide-width paving is provided. The paving machine includes a conveyor system, an auger system disposed adjacent to the conveyor system, a screed adjacent to the auger system, and sensing circuitry configured to sense paving material height at one or more of an entrance to the conveyor system and a front side of the auger system to sense or detect underflow or overflow conditions of the paving material. The sensed heights are communicated to control circuitry of the paving machine, through signals from the sensing circuitry, and control circuitry controls rate of movement of one or more of the conveyor system and the auger system.

A paver extension bracket device automates extension and retraction of a paver platform extension to correspond to and be driven by extension and retraction of a pre-existing laterally extendable paver mechanism. The device includes a bracket configured for coupling to a laterally extending paver mechanism of a paver. A post is coupled to and extends from the bracket such that said post is configured for coupling to a paver platform extension such that the paver platform extension is extended and retracted respectively by extension and retraction of the paver mechanism.

A paving machine is disclosed. The paving machine may have a screed assembly having a left screed section and a right screed section. The paving machine may also have a crown actuator configured to pivot the left and right screed sections about the centerline. The paving machine may have a crown profile sensor configured to detect the crown profile (DP), and a cross slope sensor configured to detect a cross slope (QNL*, QNR*) of the screed assembly. Further, the paving machine may have a controller configured to determine the crown profile (DP) and a cross slope (QNL*, QNR*) of the screed assembly. The controller may calculate a left cross slope (QNL) of the left screed section and a right cross slope (QNR) of the right screed section based on the determined crown profile (DP) and the determined cross slope (QNL*, QNR*), and display the crown profile on the display device.

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.

An apparatus for screeding concrete to produce a level finished surface includes a frame assembly having a pair of spaced vertically oriented stabilization legs secured to the front end thereof supporting a generally horizontal front member. An extendable boom assembly is secured to said frame assembly at a first end and to a screed head at a second end. A side-step assembly includes an actuator with an extendable arm secured to said boom assembly to impart generally lateral motion.

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 adjustable width support assemblies are connected between the sideform assemblies and 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. The spacers may be hung on a plurality of hanger rods. Each of the hanger rods may have a hydraulic nut on one end thereof for clamping the spacers between the sideform assembly and the center portion.

A channel plate arrangement for a road finishing machine comprises an extension means including a first channel plate which is movably mounted in a horizontal direction with respect to the channel plate arrangement to variably adjust an effective width of the channel plate arrangement, and a second channel plate connected to the first channel plate. The second channel plate is arranged at the first channel plate in a pivoting manner to variably adjust the effective width of the channel plate arrangement.

The disclosure relates to a road making machine in the form of a road finishing machine or a charger vehicle for conveying laying material to a road finishing machine. The road making machine is self-propelled and comprises a travel drive, a material bunker, a driver stand, and a photovoltaic system. The photovoltaic system includes at least one photovoltaic module for generating electric current, a power storage system, and a charge controller.

An asphalt finisher includes a tractor, a hopper disposed in front of the tractor and configured to receive a pavement material, a conveyor configured to convey the pavement material in the hopper to a rear side of the tractor, a screw configured to spread the pavement material conveyed by the conveyor at the rear side of the tractor, a screed configured to compact the pavement material spread by the screw at a rear side of the screw, an information acquisition device configured to obtain information on a road to be paved, and a control device. The control device is configured to support an operation of aligning the center of the tractor with the center of a pavement target area based on the information obtained by the information acquisition device.
