摘要
表面铺装是影响城市热岛现象的重要因素之一,而蒸发冷却是可以降低铺装表面温度的一种有效方法。研究可知现今采用的一般表面铺装材料不具有吸水性和保水性,而蒸发冷却效果仅仅在表面洒水后的短暂时间内产生作用。本文通过对蒸发冷却效果的定量分析,研制开发出了具有吸水性和保水性的表面铺装材料,具有长时间稳定的蒸发冷却效果,可在一定程度上缓解城市热岛现象。
Surface pavement is one of the important factors that has influence on heat island phenomenon,while evaporative cooling is an effect method to decrease the road surface temperature.Based on the studies,it was known that the normal surface pavement material does not have the properties of water absorption and water retention,the evaporative cooling could only have effect during the short time period after the surface was watered.In this paper,with the quantitative analysis,the surface pavement material with water absorption and water retention properties was developed.This material had steady performance and could relieve the heat island phenomenon at some extent.
