Technical Brief on RollerCompacted Concrete Pavement
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

RollerCompacted Concrete (RCC)
Rollercompacted concrete, or RCC, takes its name from the construction method used to build it. It's placed with conventional or highdensity asphalt paving equipment,then compacted with rollers. Rollercompacted concrete has the same basic ingredient as conventional concrete: cement, water, and aggregates, such as gravel or crushed stone.
Loosening Compacted Soil: How To Improve Soil Compaction
Loosening compacted soil can be done a number of ways. For larger areas, like lawns, you can use an aerator. These machines will either remove plugs of soil from the ground or will puncture the ground and give the soil room to decompress. For smaller areas, you can work in organic materials like compost, peat moss and other organic materials. Gypsum is another amendment that can be used for .
