Preliminary Field Investigation of Intelligent Compaction of Hot-Mix Asphalt
Attention is being directed toward intelligent compaction (IC) of pavement layers, which uses rollers especially manufactured to determine the degree of compaction and regulate the compactive effort required to produce a pavement layer with the optimum density. An IC roller should also have the capability to record a mix characteristic that can be correlated with the density of the final product. In this study, a small field investigation was conducted to determine if the stiffness measured by a particular IC roller correlated with the density of the thin surface layer of asphalt being compacted, thereby leading to a possible future end-result acceptance tool. The roller patterns were also used to determine whether the IC roller was more efficient than a conventional vibratory roller, i.e., whether fewer roller passes were required than with a conventional roller.
