Claim Text:
1. A method for validating compaction of a plurality of layers of work material at a work site, the method comprising: (a) passing a compaction machine over a first layer of work material at the work site; (b) receiving compaction data from a sensor indicative of a state of compaction of the work material as the compaction machine passes over the work material; (c) receiving position data from a location sensor indicative of a height and a position of the compaction machine in the work site; (d) determining a structural parameter of the work material based on the compaction data and the physical properties of the compaction machine as the machine passes through the work site; (e) associating the structural parameter with the position data for the height and the position of the compaction machine in the work site where the compaction data was received; (f) collecting structural parameters and associated position data across the work site; (g) saving the structural parameters with the associated position data; (h) repeating steps (a)-(g) for a second layer of work material at the work site; and (i) generating a three-dimensional map of the work site showing the structural parameters and associated position data for different locations in the work site and for different layers of work material in the work site, including a thickness of each layer for different locations.
