The performance and durability of Portland cement concrete pavements (concrete pavements hereafter) are extremely affected by the vehicle loads and the daily fluctuation of temperature and relative humidity. Tensile stresses and strains are created and gradually increase. When the tensile stresses exceed the tensile strength of concrete pavements, cracking of concrete initiates and propagates through the complete depth of the concrete pavements. As a result, the performance of concrete pavements deteriorates and may be out service. In this study, the performance and durability of concrete pavements was improved by using a new reinforcement material, called geogrid materials. Geogrid materials are geosynthetic materials and have advantageous structural properties such as high tensile strength and high resistance of corrosion. Geogrid materials provide a complete bond with the surrounding concrete because of their openings’ shape and the roughness of their nodes. These properties encourage using geogrid reinforcement materials with concrete pavements. The main objective of this research study was to investigate the effect of geogrid materials on the performance and durability of concrete pavements under static and cyclic loads and under ambient environmental conditions.
