A paving system includes a machine having a plurality of ground-engaging elements and a frame. The machine may be a paving machine having a receiver configured to receive electronic data indicative of a non-uniformity in a substrate within a region to be paved with a mat of paving material. The paving system further includes an electronic control unit configured to control compactor interaction with the mat of material according to a mat smoothness criterion, including controlling compactor interaction with the mat of material in response to data, such as screed control data, indicative of the non-uniformity in the substrate.

Paving system and method for controlling compactor interaction with paving material mat

A machine system includes a compactor having a frame, at least one compacting element coupled with the frame, and a sensing system configured to output signals including electronic data indicative of a varying response of material within a work area to interaction of the compactor therewith. The machine system further includes an electronic control unit coupled with the sensing system and configured to link the electronic data with location data for the work area, and further configured to assign each one of at least two different compaction targets to different regions of the work area responsive to linking the electronic data with the location data. The machine system may further include a computer readable memory storing a compaction interaction planning algorithm, whereby the electronic control unit determines a compactor interaction plan for navigating the compactor within the work area.

Machine system and operating method for compacting a work area

A method of operating a paving system includes establishing a plan for paving a work area which is based on a positional temperature model. The method further includes receiving temperature data for paving material and comparing the temperature data with data predicted by the positional temperature model. Operation of the paving system is adjusted where actual data differs from model predicted data. A paving system and control system are provided having an electronic control unit configured to compare electronic temperature data with a positional temperature model for paving material. The electronic control unit can control machines of the paving system based on comparing actual data with model predicted data, and can further update either or both of a plan for paving a work area and the positional temperature model itself based on differences between actual data and model predicted data. A complete temperature profile of a paving work area, including a comparison with the model may be recorded in computer readable memory for forensic and predictive analysis.

Paving system and method

A paving system includes a machine having a frame with a plurality of ground-engaging elements coupled with the frame, and a height adjustable screed coupled with the frame. The paving system may also include a paving control system having a receiver configured to receive screed control data indicative of a position of the height adjustable screed relative to a reference position. The paving control system may further include a computer readable memory storing a control algorithm, which may include a smoothness estimating algorithm and a screed adjusting algorithm. An electronic control unit is coupled with the computer readable memory and is configured via the control algorithm to determine a smoothness value for a region of a mat of material which corresponds with an irregular pattern of screed position, in response to screed control data received via the receiver.
