| This study was undertaken measure and analyze the thermal environment characteristics of the grey permeable cement concrete pavement(GPCCP), the permeable cement concrete brick pavement(PCCBP) compared with impermeable cement concrete pavement(ICCP) and bare soil(BS) under the summer outdoor environment. Following is a summary of major results. 1) The peak surface temperature was greatest in the GPCCP(54.2$^{circ}C$) followed by ICCP(47.2$^{circ}C$) on August 2, 2002, the hottest day(35.3$^{circ}C$ of highest temperature) during the experiment; peak temperature in the ICCP and BS were 45.5$^{circ}C$ and 45.3$^{circ}C$, respectively. 2) Analysis of heat budget of the pavements has revealed that the heat environment was worse in the GPCCP than that in the ICCP and that this was mainly due to a low albedo in the former(0.2) relative to that of the latter(0.4). 3) Analysis of heat budget of the pavements has revealed that the heat environment was worse in the GPCCP than that in the PCCBP, BS and that this was mainly due to a decreased latent heat resulting from a time dependent decreasing impact of rainfall. 4) It is necessary to make cool pavements to further studies on light-colored surface materials for attaining high albdo and construction methods which can enhance the latent heat through the continuous evaporation from pavements surface. 5) Vertical arrangement of pavement layers has not been considered in the present study, which has been on the heat characteristics of the surface layer materials. Accordingly, future studies will have to be empasized on pavement methods including the vertical arrangement of the pavement layers. |
