Abstract: 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.

Abstract: The present disclosure is related to a paving machine including a tractor, a screed assembly coupled to the tractor, and an auger coupled to the tractor and disposed between the tractor and the screed assembly. The paving machine includes an actuator coupled to the auger and the tractor. The actuator is configured to move the auger relative to a ground surface. The paving machine includes a sensor coupled to the tractor and configured to detect an obstruction on the ground surface. The paving machine includes a controller in communication with the actuator and the sensor. The controller is configured to receive a signal from the sensor assembly indicative of the obstruction. The controller is further configured to control the actuator to raise the auger.

Abstract: A walkway assembly for a paving machine is disclosed in the present disclosure. The walkway assembly comprises a main walkway, an extender walkway, and a wheel assembly. The extender walkway telescopically extends and retracts relative to the main walkway. The wheel assembly comprises a hollow guard, a pin, and a wheel. The hollow guard includes a first hole in a first transverse member and a second hole in a second transverse member. The pin extends therethrough between the first hole and the second hole of the hollow guard. The pin couples the wheel assembly with the main walkway. The wheel is mounted on the pin and positioned inside the hollow guard. The wheel extends above the hollow guard and is in a rolling contact with the extender walkway.

Abstract: A walkway assembly for a paving machine is disclosed herein. The walkway assembly includes a main walkway, an extender walkway, and a wheel assembly. The extender walkway telescopically extends and retracts relative to the main walkway. The wheel assembly includes a guard, a pin, and a wheel. The guard includes six surfaces mutually perpendicular to each other. The guard includes a cavity which defines a first opening in the first surface and a second opening in the third surface. The guard also includes an insert hole longitudinally extending from the second surface to the cavity. The wheel having a through hole is positioned inside the cavity and extends partially outwards from the guard through the second opening in rolling contact with extender walkway.

Abstract: A walkway assembly for a paving machine is provided. The paving machine includes a centering plate attached to a stairway, and a coupling assembly which couples the centering plate to a main walkway of the walkway assembly. The coupling assembly includes a bracket assembly, a first member, and a second member. The first member includes a first end with a first slot and the second member includes a second end with a second slot. A first disc and a second disc are in contact with a first surface and a second surface of the centering plate, respectively. The first disc includes a first recess to fit a first fastener end of a first fastener, allowing the first disc to pivot. The second disc includes a second recess to fit a second fastener end of a second fastener, allowing the second disc to pivot.
