To address these challenges, it is essential to understand the influence of climate change on the key environmental parameters on pavement design. The Climate Adaptation and Asphalt Selection Tool (CAAST) was employed to capture the variations of climatic loadings on some of the key environmental parameters, while the Pavement Mechanistic-Empirical Design (PMED) tool was utilized to get the trends of the rest of the parameters for the four pavement design cycles of 25 years, ranging from 1995 to 2094. The analysis incorporates historical (1995\u20132019) and projected short-term (2020\u20132044), intermediate-term (2045\u20132069), and long-term (2070\u20132094) hourly climate data from Environment and Climate Change Canada (ECCC), which were dynamically downscaled using the Canadian Regional Climate Model 4 (CanRCM4) for 17 different cities across Canada. Modern-Era Retrospective analysis for Research and Applications, Version 2 (MERRA-2) historical (1995\u20132020) climate data were also used to compare the ECCC\u2019s historical data to understand the trends of key climatic parameters. The downscaled climatic data were then fed into the CAAST and PMED to calculate critical environmental parameters such as Mean Annual Air Temperature (MAAT), Mean Annual Lowest Air Temperature (MALAT), Mean Annual Highest Air Temperature (MAHAT), Mean Annual Degree Days (MADD), Mean Annual Precipitation (MAP), freezing index, and average annual freeze-thaw cycles. It is found that the MAAT increases consistently across all cities, especially northern cities, which would experience a sharp increase, threatening permafrost stability. MALAT is also projected to rise, reducing risks of low-temperature cracking, particularly in southern regions, while MAHAT is expected to double in some areas, intensifying rutting. The MADD is found to rise significantly, indicating extended warm seasons; however, increasing MAP over the design cycle weaken pavement subgrade. The freezing index is declining, but freeze-thaw cycles in the Northern region tend to intensify the transitional zones, exacerbating pavement deterioration. These findings emphasize the importance of incorporating climate projections into road design for improved resilience.<\/div>\n<p>Contributors: <a href=\"https:\/\/carleton.ca\/artel\/people\/sajib-khan\/\">Khan S<\/a>,\u00a0Maadani O, <a href=\"https:\/\/carleton.ca\/artel\/people\/dr-kamal-hossain\/\">Hossain K.<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Abstract: Climate change has introduced significant challenges to the performance and durability of flexible pavements due to variations in temperature, precipitation, and freeze-thaw cycles.
