Abstract: A control system for controlling operation of a vibratory system and a tamper system of a paving machine includes a first input device, a second input device, and a controller. The first input device is operable to provide a first speed signal for operating the vibratory system at a desired first rotational speed. The second input device is operable to provide a second speed signal for operating the tamper system at a desired second rotational speed. The controller receives the first speed signal and the second speed signal from corresponding ones of the first and second input devices and compares the desired first rotational speed and the desired second rotational speed. Based on the comparison, the controller determines if the desired first and second rotational speeds lie within a pre-defined range from each other. Based on the determination, the controller modulates at least one of the first and second speed signals.

Abstract: A material feed system for a paving machine includes a first sensor assembly, a second sensor assembly, and a controller configured to independently operate each of a left material feed mechanism and a right material feed mechanism with respect to one another and, selectively, in a first mode and a second mode. In the first mode, a speed of each of a left auger, a left conveyor, a right auger, and a right conveyor is automatically adjusted. In the second mode, the speed of at least one of the left auger, the left conveyor, the right auger, and the right conveyor is manually set by an operator input, one of the left material feed mechanism and the right material tied mechanism is operated in the first mode, and the other of the left material feed mechanism and the right material feed mechanism is simultaneously operated in the second mode.

Abstract: A system for automatically controlling operation of a milling drum on a cold planer includes an input device, a display device, a memory device configured to store a database of recommended plunge velocities at which a rotating milling drum having particular operational characteristics should be lowered into a pavement surface to break up and remove pavement material for various depths of cut to be achieved by the milling drum, and a processor in communication with the input device, the display device, and the memory device.

Abstract: A screed assembly for a paving machine, the screed assembly includes a screed frame, a screed plate attached to the screed frame, a wear plate attached to the screed frame, a tamper bar mounted to the screed frame and configured for up and down reciprocating motion relative to the screed frame, and an eccentric drive mechanism mounted on the screed frame and configured for driving the tamper bar up and down in a reciprocating manner relative to the screed frame. A bottom portion of the tamper bar is configured to slide along the wear plate, which is attached to the screed frame in between the screed frame and the reciprocating tamper bar. The tamper bar includes at least two intersecting chamfered surfaces with different angles from each other and relative to the screed plate at a leading edge of the tamper bar facing in a direction of travel of the paving machine as the paving machine is applying paving material to a surface.
