“…These issues cause high maintenance costs over the years and if not properly addressed can lead to loss of lives. In comparison with asphalt, concrete pavements have many advantages, including lower life cycle costs, greater resistance to wear, longer lifespan, reduced environmental impact, and easier management of maintenance and repairs [20]. In addition, concrete pavements are commonly utilized in high-load-bearing applications, such as highways, airports, and bridge decks, due to their durability and ability to provide long-lasting solutions [21].…”

The urban heat island (UHI) effect occurs when cities and towns warm up more than the surrounding rural areas because they have more structures and less vegetation and soil. The issue can be lessened by implementing a pavement solar collector (PSC) system, which converts heat from the pavement’s surface into thermal energy. In this work, the authors analyze the effect of pipe depth (85 mm to 50 mm) and spacing (200 mm to 100 mm) on the efficiency of heat extraction from the surface while taking pavement structural performance into account using the ANSYS Fluent program. The modeling approach was validated against the previous studies. According to the findings, a concrete water harvesting system may achieve the maximum outlet temperature with the least impact on traffic loading by using a distance of 100 mm and a depth of 85 mm. The load’s impact is 51% less than that of the model that predicted the highest outlet temperature, and the outside temperature is reduced by 3.9%. The outcomes here demonstrated that concrete might be employed in the PSC system as an alternative to asphalt.
