Road Well-Traveled: Implications of Climate Change for Pavement Infrastructure in Southern Canada

Relatively little research has been completed to investigate the potential impacts of climate change on pavement infrastructure despite the dependence of Canadian economic and social activity on road transport, and the documented influence of climate and other environmental factors on the deterioration of pavements. A review of pavement management practices and engineering models and approaches used to monitor, assess and predict flexible pavement performance revealed that climate - and thus potentially climate change - is an important consideration in at least three deterioration processes: thermal cracking, frost heave and thaw weakening, and rutting. Two sets of case studies were undertaken in order to investigate these generalized impacts of climate change in greater detail. The first set of case studies examined deterioration-relevant climate indicators that are routinely applied or referenced in the management of pavement infrastructure. The second set of case studies involved applying the newly developed Mechanistic-Empirical Pavement Design Guide (MEPDG) to assess the impact of pavement structure, material characteristics, traffic loads, and changes in climate on incremental and terminal pavement deterioration and performance.
