• Abstract:
  A key step toward ensuring the desired long-term performance of pavements in roadways is effective compaction. The limitations of conventional compaction techniques and current density-based acceptance practice in highway construction have led to non-uniform and unsatisfactory compaction of the pavement materials. Intelligent Compaction (IC) technology has the potential to significantly improve the consistency and uniformity of compaction. However, despite recent advancements in IC technology, several challenges remain to be addressed to enhance IC performance. This project attempted to explore the possibility of utilizing compaction measurement values (CMVs) as a function of vibration amplitude and frequency in the control system with the goal of optimizing the compaction process. In addition, it was attempted to identify potential wireless sensing systems and possible integration with IC roller for field applications. The analysis of data from an IC project indicated that linear models can reasonably express the CMVs as a function of vibration amplitude and frequency at different sections of the road. However, the variability of CMVs caused by factors both from the roller and the pavement side makes it difficult to obtain strong correlations between CMVs, vibration amplitude and frequency. In terms of enhancing performance of IC using wireless sensing, considering the complexity of sensing in subsurface, passive wireless sensing appears to be a better choice among existing wireless sensing systems. Proper pressure sensor ruggedization/packaging is critical, particularly for the sensors embedded right below the surface of the pavement.
