In recent years, severe climate changes have led to extremely hot weather to severe rainfalls resulting in flooding and disruption of transportation infrastructure. For example, in the event of flooding, pavements deteriorate faster due to the presence of water on the pavement and hence require more frequent maintenance. Although there have been noticeable changes in weather patterns, the pavement design inputs have not been improved or updated to reflect the weather changes. However, there is noteworthy progress in the research world that is working to assign weight to climate conditions and pavement performance and hence changes to pavement design standards for long sustainable transportation infrastructure. As part of our ongoing funded research, we are identifying the status of the research and approaches being used to study climate change impacts on pavement performance and maintenance hence a framework for future research and pavement design and maintenance standards can be established. As part of our proposed presentation, we will elaborate on our findings related to sources of climate data being used, weights of climate parameters on the pavement performance being noticed, and our findings of missing research in the area that needs to be addressed. The research findings are expected to benefit researchers, public agencies, and engineers to set future research direction, design, and operation of pavement-related transportation infrastructure.
