Abstract: A paving machine including an adjustable screed assembly is provided. Actuators adjust the screed assembly into the plurality of different configurations. Sensors sense a respective configuration parameter indicative of the configuration of the screed assembly. A controller is configured to save a first set of parameters including the configuration parameters and save a second set of parameters including the configuration parameters in response. The controller is configured to recall one of the first set or second set of parameters, and adjust automatically the configuration of the screed assembly to correspond to the configuration parameters included in the recalled first set or second set of parameters.

Abstract: A screed includes a frame and a plate. The frame includes a bottom surface and a plurality of mounting members. The plurality of the mounting members project from the bottom surface. At least one of the plurality of the mounting members is longitudinally and transversely offset relative to the other mounting members. Further, the plate is coupled to the frame by the plurality of the mounting members.

Abstract: A walkway for a screed includes a main walkway and an extender walkway coupled to the main walkway and an extender frame of the screed. The extender walkway is slidable relative to the main walkway along a sliding direction. Further, the extender walkway and the extender frame are pivotable relative to each other about a walkway pivot axis, the walkway pivot axis being substantially perpendicular to the sliding direction.

Abstract: Asphalt paving machine includes screed assembly, plurality of lower and upper plate fasteners, and upper and lower screed plates, each having openings, and an electric heater at least partially disposed between the plates. Upper and lower plate fasteners extend into openings of the respective upper and lower screed plates and bores of a frame portion of the screed assembly to couple the plates to the frame portion. The upper plate fasteners couple the upper screed plate to the frame portion independently of the lower screed plate, so the lower plate is displaceable from the upper plate and the frame portion.

Abstract: A tamper bar mechanism includes a drive shaft with an eccentric section on the shaft. A tamper drive member is driven by the eccentric section and drives a tamper bar between an upper position and a lower position to define a tamper stroke length. A stroke adjustment link is operatively connected to the tamper drive member and a stroke adjustment mechanism is operatively connected to the stroke adjustment link to adjust an angular orientation of the stroke adjustment link relative to the path of travel of the tamper bar and adjust a length of the tamper stroke length. A paving machine and a method of adjusting the tamper stroke length are also provided.

Abstract: A system and method to control heating of a screed assembly in a paving machine is disclosed. The system and method includes providing a plurality of screed elements in communication with a respective one of a plurality of circuit breakers through a respective one of a plurality of relays. The system and method additionally includes providing a control system in communication with the plurality of screed elements and the plurality of relays and, receiving inputs by the control system to generate an output signal based upon the inputs. Heating of each of the plurality of screed elements is accomplished in response to the output signal.
