Construction of safe, smooth, and durable pavements requires good design, sound selection of materials and mix design, and well-controlled construction processes. The Federal Highway Administration's Concrete Pavement Technology Program (CPTP) is helping designers, material suppliers, contractors, and State agencies improve portland cement concrete pavements by addressing some of the critical gaps in knowledge. The CPTP will produce practical and usable tools, guidelines, methods, and software to be used in the selction of materials, mix, and pavement design and operation. This followup article describes the Program's progress and highlights over the past year (2002-2003), beginning with selected CPTP projects in advanced pavement design systems.
