In a single pass, workers in upstate New York placed a 10-inch-thick roller compacted concrete (RCC) pavement. This job was the largest RCC pavement project ever done at the time.
Aggregate moisture content had to be monitored constantly because moisture differences can greatly affect the compacted density measured for acceptance. Based on aggregate moisture, plant operators adjusted water added at the plant to produce a uniform mix.
At cold joints workers saw cut the joint several inches in from the side, removed the waste material, and applied a grout before paving the next lane.
To cure the RCC pavement, sprinklers were run for an hour every 6 hours. After the first sprinkling, the surface was covered with polyethylene-coated burlap. Sprinkling on top of the sheeting helped replace moisture that escaped at the seams.
