Abstract. Global warming is increasing worldwide, leading to recurring climatic hazards each year. These hazards have a negative influence on the performance of infrastructure, most of which are inadequately prepared to resist the effects of climate change. Roadway system is being negatively impacted by the severe Global Warming, which is characterized by extreme heat and severe flooding. The objective of this study is to examine the impact of various factors on the performance of concrete pavement under varying weather conditions, including extreme heat and flooding. The goal is to create designs and tactics that will make concrete pavements more robust in these challenging circumstances. This research examines the characteristics of concrete and the dimensional configuration of concrete pavement using FEACONS IV to evaluate their influence on the concrete pavement’s performance under severe heat and flooding events. This study’s main findings from FEACONS IV analysis are as follows. With a lower elastic modulus, sufficient flexural strength, and aggregates with a lower coefficient of thermal expansion, concrete pavement may have an increased load-carrying capacity Increasing Concrete slab thickness can reduce stress caused by load and temperature. Increased subgrade modulus reaction value under flooding circumstances enhances pavement strength. Nevertheless, under conditions of severe temperatures, a substantial subgrade reaction modulus has the potential to increase the stress caused by temperature and load. Concrete pavement with porous limestone aggregate shows a low coefficient of thermal expansion and elastic modulus, indicating that it could outperform concrete pavement made with river gravel or granite. The implications of the findings lead to increased temperatures which will result in the degradation of pavement. It is necessary for agencies to consider a rise in temperature when designing, constructing, and maintaining pavement. Flooding causes the concrete slab and subgrade layer of a pavement to become saturated, which negatively impacts the pavement’s performance over time.
