Abstract: The first step in repairing concrete flat surfaces is a basic understanding of the product. Concrete is a rigid paving material and as such requires a uniform base to rest on. Concrete can be used to span openings, but when designed for that purpose it usually contains steel reinforcement. In the mixing and placement of concrete, more water is needed for workability than is required to hydrate the cement. Once pavement is in place, contractors are forced to deal with distress that occurs either from errors during construction or from use that exceeds what the pavement is designed for. The best time to repair concrete is early in the failure mode. Most distress starts out minor and becomes major if ignored, thus, a distress survey of pavement every one to two years is recommended.
