Abstract:

The long-term performance of asphalt pavements depends on the quality of the subgrade and ; asphalt layers. Intelligent compaction methods continuously monitor the modulus/stiffness of ; subgrade and asphalt layers during compaction process and have been proposed for ensuring ; uniform compaction. The use of the Intelligent Compaction Analyzer (ICA) developed at the ; University of Oklahoma in Norman, OK in determining the subgrade modulus and asphalt layer ; density/dynamic modulus during construction was addressed in this project. Several case ; studies were conducted to demonstrate the application of the ICA in real-time estimation of ; compaction quality. Results from these case studies show that the ICA was able to estimate the ; modulus of the stabilized subgrade with accuracy suitable for the control of compaction quality. ; Similarly, the ICA was found to accurately estimate the density/dynamic modulus of asphalt ; layers during construction of asphalt pavements. Project results demonstrate that the ICA was ; helpful in identifying and remediating the under-compacted regions in stabilized subgrades as ; well as asphalt layers. It was also found that the average subgrade modulus, average asphalt ; layer density/dynamic modulus, and overall uniformity of compaction could be improved with the ; use of the ICA.
