Pavement heats the near-surface air and affects the thermal comfort of the human body in hot summer.
Because of a large amount of connected porosity of porous Portland cement concrete (PPCC), the thermal parameters of PPCC are much different from those of traditional Portland cement concrete (PCC).
The temperature change characteristics of PPCC and the effects on surrounding environment are also different.
A continuous 48-hour log of temperature of a PCC and five kinds of PPCC with different porosity were recorded in the open air in the hot summer.
The air temperatures at different heights above concrete specimens were tested using self-made enclosed boxes to analyze the characteristics of near-surface air temperature.
The output heat flux of different concrete specimens was calculated.
The results show that the PPCC has higher temperature in the daytime and lower temperature in the nighttime and larger temperature gradient than the PCC.
The air temperature above PPCC is lower than that of PCC after solar radiation going to zero at night.
The total output heat flux of PPCC is slightly smaller in the daytime and significantly smaller at night than that of PCC.
The results of tests and calculations indicate that PPCC contributes to the mitigation of heating effect of pavement on the near-surface air.
