Unlike conventional concrete, which uses internal vibration for consolidation, roller-compacted concrete is externally vibrated with rollers.
Roller-compacted concrete is placed similarly to asphalt. The concrete is delivered in trucks and then spread by modified asphalt rollers.
World of Concrete gave attendees an up-close and personal look at how roller-compacted concrete is placed at a simulated jobsite.
Attendees stopped by RCC Live! to see live demonstrations of a roller-compacted concrete test-strip placement.
The purpose of the demonstration is to show attendees what they need to do to prepare for an RCC project.
Wayne Adaska, director of pavements for the Portland Cement Association, discusses the importance of compaction.
