This video details how to make strength test cylinders for testing Roller Compacted Concrete (RCC). It is based on ASTM C1435 Standard Practice for Molding Roller-Compacted Concrete in Cylinder Molds Using a Vibrating Hammer.
I have read about an article about modified compaction test and RCC for experiments. Same procedure in ASTM D 1557. But I'm not sure if this is a good way to experiment on RCC since the unit weight decrease from 7.7% compared to Roller vibrator.
