AccuGrade Compaction is a new GPS system designed for mapping and soil-compaction measurement on soil compactors. The system uses a color display that provides compaction data, including working speed, amplitude, frequency, compaction values and number of passes. The compaction values, says Caterpillar, are displayed as a graduated color scale that is calibrated to match the characteristics of the material being compacted. The target compaction value is presented in a particular color, and when the color of an area matches the target color, the operator knows that optimum compaction has been established. The system, says Cat, provides documentation in the form of a historical record of work completed, with compaction values and pass information correlated to GPS-determined positions.
