Thermal Behavior of a PCM Incorporated Concrete Pavement
Conversion of natural landscapes to artificial structures that store sensible heat has led to urban heat island (UHI) effect and thermal distresses in the pavements. Reducing the pavement temperature without affecting its structural and service properties is an emerging problem of research importance. The current study evaluates the thermal behavior of phase change material (PCM) incorporated concrete pavement. A commercially available organic PCM with melting temperature 35–65℃ was used in this work. As direct incorporation of PCM adversely affects the mechanical strength of concrete, the PCM was impregnated into expanded clay aggregates (ECA) and coated with cement paste for encapsulation. The thermal and mechanical performances of this PCM incorporated concrete pavement was evaluated for a period of 1 month. A maximum temperature reduction of up to 3.68℃ was observed by the incorporation of the PCM.
