Abstract
In order to reduce the road surface temperature and improve the efficiency of heatconduction within the pavement, a peg-top oriented heat conduction structure(POCS) was designed. Meanwhile, two indexes, the peak temperature at the roadsurface and accumulated solar radiation absorption, of the structure werecompared with those of the contrast structure. Results showed that the peaktemperature at the road surface was reduced by 4.4°C, and the accumulated solarradiation absorption was increased by 11.3%. These suggest that the POCS canrelease less heat to atmosphere and absorb more solar radiation, and isexpected to be applied to urban roads to mitigate the urban heat island effect
