• Resumen

  • Continuous Compaction Control (CCC) and Intelligent Compaction (IC) systems show great promise for improving the efficiency of field compaction and revolutionizing the compaction control process. A number of recent studies on compacted granular soils have shown that real-time acceleration monitoring of vibratory compaction systems allows for effective evaluation of compacted soil stiffness, leading to improved field construction.

    Since vibratory compaction is generally not effective for fine-grained soils, machine drive power (MDP) compaction systems have been developed, and are in the process of being studied further. This paper presents preliminary results from a compaction field study performed in the State of Delaware using a MDP equipped CCC system. The effectiveness of continuous compaction control in this study will be assessed and compared with two in-situ evaluation techniques that are commonly used to measure soil modulus.
