The Roller Compacted Concrete (RCC) offers a different concept in the creation of pavement and concrete dams it’s dry Beaton (Zero Abrams slump), with a low water content, and includes of dense mix consisting of graded coarse aggregate, and cementati
ons materials, and water, this makes it so difficult to compact it in big thicknesses layers without using large energy rollers compactors. concrete conveys by trucks, placed and compacted by using equipment asphalt pavement. The main advantage of this technique is in reducing the completion time and cost savings in labor and the possibility of replacing traditional materials in road paving. It also provides a solid surface smooth and polished, and would facilitate the operations of traffic expected in all circumstances and various factors such as axial loads and environmental conditions.
This paper presents a new technology for the manufacture of Roller compacted concrete samples by applying a mechanism of Vibro-compaction pressure on samples of fresh concrete. It had Been manufactured concrete samples differ from their limestone filler content, and after conducting an analytical study of the results of tests of these samples has been reached to ideal feller content for this type of concrete by reliance on the mechanical strength and speed of evolution with time as criteria for the basic design.
