Abstract
A paving method may include acquiring temperature data corresponding to paving material distributed over a work area; developing a compaction boundary map based on the acquired temperature data; and steering a compactor machine based at least in part on the compaction boundary map.
Claims20
A paving method, comprising:
- acquiring temperature data corresponding to paving material distributed over a work area, wherein acquiring temperature data includes scanning, with a sensor mounted on a paving machine, the paving material located behind the paving machine, receiving position data for the paving machine from a location sensor, and associating the acquired temperature data with the position data;
- developing a compaction boundary map based on the acquired temperature data, wherein developing the compaction boundary map includes using the acquired temperature data and the associated position data to identify one or more areas to be compacted by a compactor machine and an area to be avoided by the compactor machine;
- and
- steering and propelling the compactor machine based at least in part on the compaction boundary map.

A paving method, comprising:
- using at least one temperature sensor mounted to a paving machine, acquiring temperature data corresponding to paving material distributed over a work area;
- developing a compaction boundary map based on the acquired temperature data and locational data associated with a path of the paving machine, wherein the compaction boundary map includes an area to be compacted by a compactor machine and an area to be avoided by the compactor machine, wherein at least a portion of the area to be avoided is within the area to be compacted;
- and
- automatically steering and automatically propelling the compactor machine based at least in part on the compaction boundary map without input from an operator.
1 more element
A paving system, comprising:
- a paving machine including:
- a temperature sensor configured to acquire temperature data corresponding to paving material distributed over a work area, and a receiver configured to receive position data for the paving machine;
- a compactor machine;
- and
- a control system configured to:
- develop a two-dimensional compaction boundary map based on the acquired temperature data and position data for the paving machine;
- and
- automatically steer the compactor machine over the two-dimensional compaction boundary map based at least in part on the compaction boundary map and without input from an operator.
