Federal Highway AdministrationFederal Highway AdministrationThe Concrete Pavement (CP) Road Map is a plan for concrete pavement research that will guide the investment of research dollars for the next several years. This TechBrief is a summary of FHWA-HRT-05-52, Concrete Pavement Road Map Volume I and FHWA-HRT-05-53, Concrete Pavement Road Map Volume II. For most of the 20th century, the same materials--portland cement concrete, high-quality aggregate, and water--were used in pavement concrete, with only minor refinements. This fairly forgiving formula allowed some variations in subgrade quality, construction practices, and other variables without sacrificing pavement performance. In today's environment, however--with new, sometimes incompatible materials, more demanding production schedules, and other pressures--the old system for constructing concrete pavements is not as malleable. The CP Road Map gives the highway community an opportunity to reinvent itself proactively through research.79
