Preliminary Field Investigation of Intelligent Compaction of HMA

About the project:

A new roadway construction concept called intelligent compaction, IC, uses rollers that have the ability to change compaction effort as the roller drum senses the stiffness of the layer.  If the stiffness measurements recorded by the roller correlate to density as expected, there is potential that the roller might be used as an acceptance tool in the future. This project is designed as a preliminary study to a national pooled fund study and will determine the correlation of density to stiffness and influence of temperature on the ability to achieve adequate stiffness/density.
