This reveals that albedo has different effects on pavement temperature in summer and winter with different peak solar radiations. The peak solar radiation intensity at around 1:00 pm is approximately 1000 W/m2 in summer in Davis, California (see Incident Solar Radiation in Fig. 8 (d) and Fig. 14 (a)). It is approximately halved to 500 W/m2 in winter (see Incident Solar Radiation in Fig. 8 (b) and Fig. 14 (a)). The temperature effect of albedo in winter is also approximately half of that in summer (−6°C/+0.1 albedo in summer and −3 °C/+0.1 albedo in winter). It implies that solar radiation positively influences the cooling effect of increased albedo (CEalbedo), and the cooling effect of increased albedo in hot climates with high solar radiation is larger than that in climates with low solar radiation. This also can be seen from the insignificant effect of albedo (∼0°C/+0.1 albedo) on the low temperature during nighttime with no solar radiation for both summer and winter.
