Portland Cement Concrete Pavement

Portland cement concrete (PCC) pavement, or rigid pavement as it is sometimes called, refers to the rigid concrete layer of the pavement structure that is in direct contact with the traffic. Typical concrete is composed of coarse aggregate (crushed stone and gravel), fine aggregate such as sand, portland cement and water.

HOW TO DECIDE MAXIMUM SIZE OF COARSE AGGREGATE TO BE

Mar 23, 2015On the other hand in smaller size aggregates the surface area is increased which increases w/c ratio and lower strength is achieved. In general for strength upto 200 kg/cm 2 aggregates upto 40 mm may be used and for strength above 300 kg/cm 2 aggregate upto 20 mm may be used.

Particle Shape and Surface Texture Pavement Interactive

Aggregate particle shape and surface texture are important for proper compaction, deformation resistance, and workability.However, the ideal shape for HMA and PCC is different because aggregates serve different purposes in each material. In HMA, since aggregates are relied upon to provide stiffness and strength by interlocking with one another, cubic angular-shaped particles with a rough

Bases and Subbases for Concrete Pavement

Portland cement concrete (PCC) was originally used as a base and was surfaced with wooden blocks, bricks, and cobblestones. The primary benefit of using PCC was its ability to spread load over a larger area than granular or bituminous bound materials, thereby allowing road builders to use less aggregate material.

Concrete is a building material made by mixing cement paste (portland cement and water) and aggregate (sand and stone). The cement-paste is the glue which binds the particles in the aggregate together. The strength of the cement-paste depends on the relative proportions of water and cement; a more diluted paste being weaker.

Reclaimed Concrete Material Material Description RMRC

Reclaimed concrete material (RCM) can be used as coarse and/or fine aggregate in Portland cement concrete (PCC) pavements. However, concrete incorporating more than about 10 to 20 percent fine RCM aggregates can suffer a reduction in quality because of the high amount of water required to maintain adequate workability of the concrete mix.
