TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 530: Construction and Rehabilitation of Concrete Pavements Under Traffic identifies practices from projects representing a wide range of conditions and techniques. The current state of the practice in constructing or rehabilitating concrete pavements under traffic relies primarily on a few high-profile and well-documented projects. Sixteen case examples were reported to illustrate successful projects conducted under a variety of scenarios. Appendices A and B are available online and are combined into one PDF document.
