Roller compaction is a compaction process that employs the use of three key components: The feeding system: carries the raw material from the mouth of the machine to the compacting unit. The compaction unit: uses two counter-rotating rolls to compact the material. The size reduction unit: mills the compacted material to the desired particle size.
Compaction Equipment. There are three basic pieces of equipment available for HMA compaction: (1) the paver screed, (2) the steel wheel roller and (3) the pneumatic tire roller. Each piece of equipment compacts the HMA by two principal means: By applying its weight to the HMA surface and compressing the material underneath the ground contact area .

Roller Compacted Concrete (RCC) Overview. Roller compacted concrete, or RCC, has the same basic ingredients as conventional concrete, but it is created from a mix that is stiff enough to be compacted by vibratory rollers. RCC is typically constructed without joints, and it does not require forms, finishing, or reinforcing.
Experiences with Roller Compacted Concrete in Kansas By Lisa Harris W hen paving a road or street, two common choices for the material are asphalt and poured concrete. Each material has its pros and cons in terms of cost, maintenance, and longevity. Now, in some parts of Kansas, there is a third option: roller compacted concrete (RCC).
The roller also a small drum installed on its front called a stabilizer roller. It is not powered. It aids the roller in keeping itself stable and simplifies the handling process. This type of roller usually also has a water sprinkler system. It is used for wet compaction. The roller can be either diesel-powered or battery-powered.
