The disclosure provides a paving machine and related methods. In one example, a paving machine includes a first group of sprayers positioned on an underside of a body of the paving machine, and a second group of sprayers positioned downstream of the first group. The first group of sprayers dispense a first product on an existing road and the second group of sprayers dispense a second product over the first product. The paving machine includes a channel positioned downstream of the second group of sprayers to dispense an asphalt mixture over the second product, and a screed positioned adjacent to the channel in contact with the asphalt mixture.

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.

A paver, in particular a slipform paver, has a machine frame supported by front and rear undercarriages and a paving device for the paving of material. The paver is provided with an apron monitoring device for generating elevation profile data or elevation profile signals describing the elevation profile of the material deposited in the apron of the paving device in a direction transverse to the working direction. A data or signal processing device receives the elevation profile data or signals. The apron monitoring device provides the data needed to allow the material to be spread more evenly across the working width of the paver during the feeding operation by means of a spreading device for spreading the material to be paved in a direction transverse to the working direction and/or to allow the spreading device to be controlled for improved spreading of the material after the paver has been fed.

A screed assembly, for a paving machine, may include a frame, a main screed and a screed plate. Additionally, the screed assembly may include an overload support system mounted on the screed assembly. Further, the overload support system may be configured to contact the surface extending beneath the screed assembly and to support the screed assembly during transport on the surface.

A self-propelled construction machine comprises a machine frame having a working means arranged thereon, and a drive means for driving left and right crawler tracks at respective predetermined chain speeds. A control unit is configured such that, based on a distance between a front reference point with respect to the machine frame in the working direction and a predetermined path, the chain speed(s) of the left and/or right crawler track is predetermined such that the front reference point moves on the predetermined path. The control unit is further configured such that, during cornering, the control is corrected based on a distance between a rear reference point with respect to the machine frame in the working direction and the predetermined path such that the distance between the rear reference point with respect to the machine frame in the working direction and the predetermined path is reduced.

A road construction machine in the form of a road finisher or feeder vehicle comprising an operator stand with a floor surface as a tread surface and a cooling system for producing a mist from a cooling agent. The cooling system comprises a tank for receiving the cooling agent and a spray apparatus for nebulizing the cooling agent into a mist. The cooling system is configured to produce the mist in the area of the operator stand, and the spray apparatus is arranged thereby at a height of at least 1.7 m above the tread surface.

Method for evaluating of a quality of a generated pavement or a generated surface, generated by use of a construction machine, especially a road construction machine, road finishing machine or milling machine, having the following steps: receiving sensor values from one or more sensors and/or a sensor system of the construction machine; determining a specific sensor value combination within the sensor values, the specific sensor value combination being assigned to a specific quality situation; and outputting an operator message dependent on the specific quality situation.

In one aspect, a method of determining lateral edges of an asphalt mat deposited by a paving machine includes obtaining thermal image data of the asphalt mat at a thermal measuring device associated with the paving machine, and determining, on the paving machine, the lateral edges of the asphalt mat based on a threshold temperature value and the thermal image data. Other aspects include a method of generating a thermal map of an asphalt mat formed by paving machine, and a system for determining lateral edges of an asphalt mat deposited by a paving machine.
