RollerCompacted Concrete Pavement • RCC mixtures require compaction with the use of vibratory, tamper bar screeds, and typically but not always with either static or vibratory rollers to achieve a target density. RCC does not involve the use of internal vibration that typically is used to consolidate concrete used in conventional paving

In geotechnical engineering, soil compaction is the process in which a stress applied to a soil causes densification as air is displaced from the pores between the soil grains. When stress is applied that causes densification due to water (or other liquid) being displaced from between the soil grains, then consolidation, not compaction, has occurred.
