Pavements are designed based on historic climatic patterns, reflecting local climate and incorporating assumptions about a reasonable range of temperatures and precipitation levels. Given anticipated climate changes and the inherent uncertainty associated with such changes, a pavement could be subjected to very different climatic conditions over the design life and might be inadequate to withstand future climate forces that impose stresses beyond environmental factors currently considered in the design process. This research explores the impacts of potential climate change and its uncertainty on pavement performance and therefore pavement design. Two tools are integrated to simulate pavement conditions over a variety of scenarios. The first tool, MAGICC/SCENGEN (Model for the Assessment of Greenhouse-gas Induced Climate Change: A regional Climate Scenario Generator), provides estimates of the magnitude of potential climate change and its uncertainty. The second tool, the Mechanistic-Empirical Pavement Design Guide (MEPDG) software analyzes the deterioration of pavement performance. Three important questions are addressed: (1) How does pavement performance deteriorate differently with climate change and its uncertainty, (2) What is the risk if climate change and its uncertainty are not considered in pavement design, and (3) How do pavement designers respond and incorporate this change into pavement design process.
