CONNECTICUT SUPERPAVE GYRATORY ROUND ROBIN - 2003

The Superpave gyratory compactor is a key component for Quality Control and Quality Acceptance for Hot Mix Asphalt (HMA). Recent research has shown test result differences between various models of gyratory compactors. It this difference is large enough, disputes may arise between the HMA suppliers and the Accepting Agencies. This project was to evaluate the differences between Superpave gyratory compactors used for Connecticut Department of Transportation Projects. Two different Superpave mixes were sent to each participating facility. The specimens were fabricated by the facility and then they were shipped back to the Connecticut Advanced Pavement Laboratory (CAP Lab) for determination of their Bulk Specific Gravity in accordance with AASHTO T166.
