Roller-Compacted Concrete (RCC) cement.org

Roller-compacted concrete has the same basic ingredient as conventional concrete: cement, water, and aggregates, such as gravel or crushed stone. But unlike conventional concrete, it's a drier mix—stiff enough to be compacted by vibratory rollers. Typically, RCC is constructed without joints.

Design of Concrete Pavement for City Streets

a concrete pavement is largely within the concrete itself due to its rigid nature, Because of the remarkable beam strength of concrete, heavy loads are distributed over large areas resulting in very low pressures on the subgrade. This makes it economically impractical to build up subgrade strength with thick layers of crushed stone or gravel.

What causes a concrete pavement to crack?

It is not uncommon for concrete pavement temperatures to exceed 45 °C (113 °F) in summertime, particularly for fast-track concrete paving (5,8). Mixtures containing certain fly ashes or lower quantities of portland cement can delay early age strength development in cooler weather.
