Intelligent Soil Compaction Systems

Abstract

This report describes intelligent compaction, a new method of achieving and documenting compaction requirements through continuous compaction-roller vibration monitoring to assess mechanistic soil properties (e.g., stiffness, modulus), continuous modification/adaptation of roller vibration amplitude and frequency to ensure optimum compaction, and full-time monitoring by an integrated global positioning system (GPS) to provide a complete GPS-based record of the compacted area. This report will interest state and local highway agency construction managers and geotechnical engineers and contractors, particularly excavation superintendents. Implementation of this system has the potential to improve infrastructure performance, reduce costs, reduce construction duration, and improve safety.
