Promising technology would revolutionize DOT check of quality and accept projects. Intelligent compaction (IC) using GPS and accelerometer to record the response of soil layers. The accelerometer readings are converted into compaction value (CMV). Mapping data of soil before and after laying out subgrade were collected. Geostatistical kriging of soil and subgrade rasters shows about 55% passes and about 82% is acceptable. Comparing spot tests to CV using IC show direct positive correlation
