What are the effects of climate change (e.g., increased temperatures, extreme weather events) on pavement performance and maintenance needs?



Climate change, with its associated increased temperatures and more frequent extreme weather events, significantly impacts pavement performance and increases maintenance needs. Higher average temperatures can lead to increased rutting in asphalt pavements, as the asphalt binder softens and becomes more susceptible to deformation under traffic loads. Increased thermal cracking is another consequence, even though higher average temperatures may seem beneficial, more extreme high and low temperature swings increase the stress....
