Abstract
Abstract The problems of soil-structure interaction involve different members or different materials behave together under applied loading. In the case of concrete pavement resting on soil under traffic loading, both concrete and soil will deform. Rigid Pavements are made of Portland Cement Concrete (PCC). It serves out two aims, to maintain a durable surface with comfortable driving for vehicles. The second purpose is to decrease the stresses on the layers of pavement beneath the surface such as subbase and subgrade. Concrete is considered a weak material in resisting tensile stresses. Therefore, when low tensile stresses are applied, rigid pavement begins to crack effortlessly. In concrete pavement, the usage of different kinds of fiber reinforcement could be an effective technique to improve these properties. Numerous kinds of fibers are utilized in the concrete pavement to behave as an alternative to ordinary reinforcement. They may differ in material like steel or plastic and could be in many shapes, and dimensions. The addition of fibers is during the mixing when the concrete is still fresh. The incorporation of different sorts of fibers could be a significant step in diminishing the cracks and achieving a higher performance of concrete. Two kinds of fibers or even more than two can be combined to achieve a mixture that produces profits for each type of fiber in this composite. In this paper, an intensive review was made to demonstrate the forms of distresses that could happen in concrete (rigid) pavement and the impact of incorporating different kinds of fibers into the concrete to enhance the concrete ability to eliminate or even delay the process of failure.
