Abstract: A system adjusts an instantaneous turn center for a paving machine having a tow vehicle and a screed assembly towed by the tow vehicle such that no portion of the screed assembly moves backward over freshly laid pavement when the paving machine paves around a curve. The system receives an input from an operator, a sensor, and/or a database. The input includes a distance and a direction from a first vertical axis defined by a traction device of the tow vehicle on a side of the tow vehicle facing the curve, to a second adjusted vertical axis defined by a point at least as far from the first vertical axis as an outer edge of the screed assembly that touches the curve. The system receives the input, and adjusts the instantaneous turn center for the paving machine to coincide with the second adjusted vertical axis.

Abstract: A material feed system for a paving machine includes a first optical sensor and a second optical sensor that are configured to generate data characteristic of paving material associated with corresponding ones of a left feed mechanism and a right feed mechanism of the paving machine. A controller is communicably coupled to the first optical sensor, the second optical sensor, a left conveyor, and a left auger of the left feed mechanism, and a right conveyor and a right auger of the right feed mechanism. The controller is configured to control the left material feed mechanism and the right material feed mechanism independently of each other such that the left conveyor and auger speeds are independently adjusted based on the data received from the first optical sensor and the right conveyor and auger speeds are independently adjusted based on the data received from the second optical sensor.
