2002 PAVEMENT - Federal Highway Administration

distress-specific performance models are needed to allow engineers to better consider the potential modes of pavement failure so that the optimal combination of materials, layer thicknesses, and design features can be selected. The importance of LTPP to the development of the 2002 Design Guide was recognized from the very start.
