A control device may obtain sensing data related to a paving material mat region laid by a screed assembly of a road paver. The control device may determine, based on the sensing data, a respective texture value and/or a respective height value associated with each portion of two or more portions of the paving material mat region. The control device may determine, based on the respective texture values and/or the respective height values of the paving material mat region, a finish value associated with the paving material mat region. The control device may cause, based on the finish value of the paving material mat region, one or more actions to be performed.

A system and method includes a paving machine, a vehicle, and one or more controllers. The paving machine includes an engine for powering the paving machine and the vehicle is associated with the paving machine. The one or more controllers are configured to determine an estimated time of arrival for the vehicle at the paving machine based on a location of the vehicle; identify a startup time for the paving machine, wherein the startup time comprises a time period between starting the engine of the paving machine and an operational parameter of the paving machine reaching a threshold value; and generate an indication to shut down the engine of the paving machine if the startup time for the paving machine is less than the estimated time of arrival of the vehicle associated with the paving machine.

A paving machine includes an implement, an elongated structure, a sensor arrangement, and one or more breakaway couplers. The implement modifies a surface during a movement of the paving machine. The elongated structure is coupled to a side portion of the paving machine and extends along a direction of the movement. The sensor arrangement includes sensor units arranged sequentially along the elongated structure. The breakaway couplers correspondingly normally retain the sensor units to the elongated structure. Each breakaway coupler includes a mounting structure and a retainer unit. The mounting structure is secured to one of the elongated structure or a corresponding sensor unit, while the retainer unit retains the other of the elongated structure or the corresponding sensor unit to the mounting structure by a retention force, which is adjustable.

A paving machine includes a mold coupled to a telescopic frame member, by which the mold side-shifts relative to a main frame. A tight clearance between the paving machine and a surface being paved may be achieved by the ability to side-shift the mold. The paving machine may also include a number of vibrator motors. A flow to the vibrator motors may be controllable by a manifold controller. The manifold controller is located on an end of the telescopic frame member. By locating the manifold controller on the telescopic frame member, an operator of the paving machine may both stand on the telescopic frame member to watch the paving mold and adjust the settings of the vibrator controller. This is advantageous in allowing the operator to achieve proper concrete consolidation by visual feedback without leaving the telescopic frame member.

A screed assembly is disclosed. The screed assembly has a screed frame that includes a main screed. Attached to the main screed is a drop arm that is used to attach the screed assembly to a work machine. An actuator device of the screed assembly adjust the main screed from a neutral position to a nulled position by rotating the main screed around an axis of the pivot pin. The screed assembly may further include a controller that determines whether the main screed is in the neutral position and adjust the main screed to the nulled position by sending a null adjustment signal to the actuator device, and the actuator device moving the main screed from the neutral position to the nulled position in response to the null adjustment signal.

A paving machine includes a tractor portion, a screed assembly, a lifting assembly configured to move the screed assembly from a raised position to a lowered position, an operator interface configured to receive input from an operator, and a control module. The tractor portion includes a plurality of tractor sensors configured to detect the presence of an object in a detection zone. The screed assembly is configured to be towed behind the tractor portion, and includes a plurality of screed sensors configured to detect the presence of an object in a detection zone. The control module is configured to receive a ‘lower screed’ input from the operator interface, receive a plurality of signals from the plurality of tractor sensors and the plurality of screed sensors, determine if an object is present in the detection zone based on the plurality of signals, automatically prevent or halt lowering of the screed assembly and direct the operator interface to display a warning if an object is detected, and direct the lift assembly to lower the screed assembly to the lowered position if no object is detected.

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 work machine includes a frame, one or more drive members coupled to the frame, an engine for providing power to the one or more drive members, one or more components coupled to the frame, and a monitoring system for monitoring wear of the one or more components. The system includes a user interface and a controller. The controller is in circuit communication with the user interface. The controller is configured to receive information inputted into the user interface by a user and send an alert notification regarding the servicing of at least one of the one or more components based on the received information.

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.

A paving machine can include a frame; a screed coupled to the frame, the screed including one or more screed plates; one or more movable extender mechanisms located at a back end of each screed plate and configured to extend and retract up and down beneath the screed plate; and a controller configured to extend the one or more extender mechanisms a pre-determined distance before the screed begins a paving operation and to retract the one or more extender mechanisms after the screed has begun the paving operation.
