PDF Thickness Design of Roller-Compacted Concrete Pavements

Roller-compacted concrete (RCC) is a relatively stiff or zero­ slump concrete mixture that is compacted by vibratory roller. RCC is capable of providing concrete with relatively high in­ pjace strength, and its engineering behavior is similar to that of conventional concrete. RCC is being used as a paving material at

Roller Compacted Concrete with Recycled Concrete

Apr 14,  · One type of CDW is Recycled Concrete Aggregate (RCA), which could be an excellent option to use as an aggregate for the pavement layer due to its physical properties. RCA was used in several types of concretes; in some researches studies, it was used as an aggregate for Roller Compacted Concrete (RCC) [8–11].

Properties and design of fiber reinforced roller compacted

Cost savings could be realized for paving projects constructed with the emerging roller compacted concrete (RCC) technology. In particular, pavement thickness reduction due to the inclusion of fibers in RCC can allow single-lift construction where two lifts of unreinforced concrete would be required.

Roller compacted concrete for highway pavements

Roller compacted concrete (RCC) has long been a known technology for paving. Looking at the more recent projects employing RCC, one thing in common can be observed: the pavement supported heavy and slow-moving traffic. This article discusses the advantages and disadvantages of RCC, mixture characteristics, and factors affecting pavement quality.

ROLLER COMPACTED CONCRETE PAVING | Igel Construction

Roller Compacted Concrete is a low water-cement ratio concrete pavement installed through a specialty paver, similar to an asphalt paver. The low slump concrete is mechanically compacted by the paver and followed quickly by double drum rollers. The density of the pavement is then checked by nuclear gauges. The compacted concrete's compressive
