Mechanistic-Empirical Pavement Design Model

Temperature, precipitation, cloud cover, freezing index, and other environmental conditions can have a significant effect on flexible and rigid pavement performance, both in actuality and in terms of what is modeled. These factors affect how the pavement layer materials behave when responding to traffic loadings and when subjected to environmental loadings. NCHRP Research Report 1151: Mechanistic–Empirical Pavement Design Model: Enhancements of Climatic Inputs, from TRB's National Cooperative Highway Research Program, explores how to improve climatic inputs and related models that can be implemented by transportation agencies.
