An aggregate spreading device includes a hopper, a conveyor system disposed below the hopper, and a spreader system extending from at least one side of the aggregate spreading device and configured to receive aggregate from the conveyor system. The spreader system includes a vertical support coupled to a frame of the aggregate spreading device, a first wall extending from a first end attached to the vertical support, and a second wall extending from a second end of the first wall. A lift actuator is configured to adjust the vertical placement of the spreader system and causing the first and second walls to move vertically.

Disclosed are a paver control system, a paver control method and a paver. The paver control system includes: an image acquisition device provided on the paver for acquiring image information of an execution device of the paver; a controller provided on the paver and electrically connected with the image acquisition device and the execution device for controlling the execution device to operate according to the image information acquired by the image acquisition device; and the execution device is provided on the paver for operating under a control of the controller. The execution device includes at least one of a driving mechanism, a prompting device and a material distributing device.

An aggregate spreading device includes a hopper, a conveyor system disposed below the hopper, and a spreader system extending from at least one side of the aggregate spreading device and configured to receive aggregate from the conveyor system. The spreader system includes a vertical support coupled to a frame of the aggregate spreading device, a first wall extending from a first end attached to the vertical support, and a second wall extending from a second end of the first wall. A lift actuator is configured to adjust the vertical placement of the spreader system and causing the first and second walls to move vertically.

A road paver includes: a head; a body including a front end and a tail end; a feeding device, disposed in the front end to convey polyurethane concrete, and the feeding device including a stirring device; a stone paving device, disposed on the tail end to spread crushed stone over a road, and the stone paving device including a stone feed bin carrying the crushed stone; and a concrete paving device, disposed between the feeding device and the stone paving device and connected to the stirring device, and used to spread the polyurethane concrete across the road.

The invention relates to a road paver or a feeder with a machine frame, a travel carriage driven by a drive unit, and a material hopper arranged in the front in the operating direction on the road paver or the feeder, the material hopper comprising a hopper bottom and side walls extending in the operating direction, at least one approach guidance aid protruding beyond the hopper bottom and the side walls in the operating direction being arranged on the road paver or the feeder in the edge region of the material hopper transversely to the operating direction. The invention further relates to an approach guidance aid of such a road paver or feeder.

A conveyor mold system for slip forming a concrete barrier has a concrete paving machine having a main frame having machine legs and machine tracks, an auger system for receiving concrete, a barrier paving mold having a hopper for receiving concrete from the auger system, a conveyor assembly main frame having a front roller and a rear roller, and a belt having a pattern with the belt positioned on the front roller and the rear roller.

The disclosure relates to a method for controlling a road finishing machine with a material bunker for receiving paving material, a screed for compressing the paving material, a drivable rear wheel and a drivable front wheel. A rotational speed of the rear wheel of the road finishing machine is measured. Moreover, a travel speed of the road finishing machine is measured. A target driving torque of the front wheel of the road finishing machine is calculated based on the measured rotational speed of the rear wheel and the measured travel speed of the road finishing machine. Then, an actual driving torque of the front wheel is adjusted to the calculated target driving torque. The disclosure also relates to a road finishing machine.

A paving assembly includes a transporter with a material feed to arrange a layer of paving material at a first distance from the transporter, a first material hopper in connection with the material feed to receive a paving material, and a superstructure selectively arrangeable on or over the transporter. The superstructure includes a frame, a further material feed extending beyond the transporter to convey the paving material at a second distance from said transporter, and a second material hopper. The superstructure includes the first and the second material hopper each arranged substantially central relative to the width of the transporter and accessible during use to allow them to be filled with paving material by a feeder for a continuous paving operation. The further material feed is arranged substantially central relative to the width of the transporter and extending over the transporter. A method of providing such a paving assembly.

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.
