| Abstract | This paper explores the impact of projected climatic loading parameters, utilizing Environment and Climate Change Canada data, on flexible pavement performance and design. Despite the expectation that flexible roads should endure various structural and environmental conditions throughout their design life, premature damage often occurs within the initial 3–5 years of service. Therefore, understanding the impact of climate change on flexible pavements in the historical, short, intermediate, and long terms becomes crucial. The pavement mechanistic empirical design (PMED) was employed to assess climatic loading effects on pavement design and performance. PMED-predicted rutting performance showed sensitivity when comparing historical and projected climatic loading parameters up to 2093. Preliminary results based on a 25-year design life for City of Windsor revealed a 72% higher rutting impact compared to historical data, shortening the pavement's design life by 28%, 56%, and 68% for short, intermediate, and long terms, respectively. |
