A Study on Radiation Cooling Effect on Asphalt Concrete Pavement Using Basic Oxygen Furnace Slag to Replace Partial Aggregates

چکیده
In this study, aggregates in asphalt concrete were partially replaced by basic oxygen furnace slag (BOFS) proportions of 45 wt.%, 55 and 75 wt.%. The thermal performances the specimens are discussed based on conductivity, emissivity, indoor outdoor temperature measurements. Consequently, wt.% specimen’s BOFS, which had a high emissivity 0.86 across sky window. tests, change was recorded to estimate performance specimens. According quantitative calculation, when substitution BOFS higher than better radiation cooling ability. Among these specimens, specimen with absorbed most heat inside body, contributing less remaining environment. Furthermore, because Newton’s energy accounted for about 90% stored within 7 h, dissipation after seventh hour primarily cooling, corresponding emission urban boundary layer. As mechanical properties, stability value, indirect tensile strength, British pendulum number (BPN) line specifications under proper substitution. conclusion, has great applicability pavements due its properties. It not only achieves goal island mitigation but also reflects concept resource sustainability.
