Abstract

Importance and necessity of concrete, as the most consumed material and the most important  construction material has been introduced in the 20th century and also after the water, the material that human consume more than everything is Concrete. While only about two centuries, past after innovation of cement and concrete and also this consuming is growing rapidly. Roller compact concrete use in two different field, the first application field is in dams and the second  application is in the Pavements. Today, composites are used in concrete products  as a new technology in the construction industry. New materials that have a special place in construction are concrete additives and amplified  fiber. In this study, main goal is to look about roller compact concrete for road pavements in terms of different technical parameters and also examine the effect of fiber in it. Because, today, cracking of concrete is considered as one of the most important issues of the day and one of practical solutions is use of fiber. The use of fiber in the  roller compact concrete improves compressive strength and tensile strength; and in all the specimens, pulse velocity through concrete decreased with use of more fiber that it is a sign of a better quality of fibered concretes than ordinary concrete. The results of this study showed the importance of application of fiber to improve performance of roller compact concrete for pavements.
