【摘要】：为了探讨透水性路面的热学行为,在现场以简易气象站及温度探测针进行气象与路面温度资料量测,以探讨不同类型路面温度变化的情形。根据试验分析结果,影响路面温度因子以日照及气温为最大,研究中建立的模型,发现面层热传导系数影响路面吸热及散热的速率,密级配沥青混凝土白天表面温度虽较其他路面低,但其面层底部温度却较透水性路面高,而透水性路面以透水连锁砖面层底部温度最低,各种路面平均热输出以密级配沥青混凝土为最大,其次为透水沥青混凝土,透水连锁砖最小,显示面层材料除热传导系数影响外,反射率也影响路面吸收热能的多少,因此选择较合适的透水性路面材料可降低城市中路面热能储存。
[Abstract]:In order to study the thermal behavior of permeable pavement, the meteorological and pavement temperature data were measured by simple weather station and temperature probe in order to investigate the temperature variation of different types of pavement. According to the results of the test and analysis, the model established in the study shows that the heat conduction coefficient of the surface layer affects the rate of heat absorption and heat dissipation of the road surface. Although the daytime surface temperature of dense graded asphalt concrete is lower than that of other pavement, the bottom temperature of the surface layer is higher than that of the permeable pavement, and the lowest temperature is at the bottom of the permeable brick layer. The average heat output of all kinds of pavement is the largest in dense gradation asphalt concrete, followed by permeable asphalt concrete, and the water permeable linked brick is the smallest. It shows that in addition to the influence of heat conduction coefficient, the reflectivity of the surface layer material also affects the amount of heat energy absorbed by the pavement. Therefore, choosing more suitable permeable pavement materials can reduce the thermal energy storage of urban pavement.
