System and method for validating compaction of a work site

A system for validating compaction of work material at a work site, the system comprising:

• a compaction machine;
• a sensor carried by the compaction machine for generating compaction data indicative of a state of compaction of the work material as the compaction machine passes over the work material;
• a location sensor associated with the compaction machine for generating position data indicative of a height and a position of the compaction machine in the work site;
• a controller configured to receive compaction data from the sensor and position data from the location sensor and to determine a structural parameter of the work material based on the compaction data and physical properties of the compaction machine, the controller being configured to associate the structural parameter of the work material with the position data for the height and the position of the compaction machine where the compaction data was received, the controller being configured to save structural parameters and associated position data for different locations in the work site and for different layers of work material in the work site and to compare the saved structural parameters and associated position data with predetermined structural design criteria for corresponding locations and layers in the work site;
• and the controller configured to generate a three-dimensional map of the work site showing the structural parameters and associated position date 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.
