摘要

透水混凝土是一種特殊形式的多孔混凝土，具有高透水性；多孔隙性

與表面粗糙的特點。美國環保署Enviromental Protection Aqency（EPA）

認為適當使用透水混凝土是控制初始急流污染及暴雨管理的最佳方式，並

利用訂定區域暴雨逕流量的限制條件，鼓勵使用透水混凝土做為道路面層

材料，但國內外對於透水混凝土在現地性質方面，尤其對透水混凝土表面

受熱所產生的溫度變化缺乏有系統的研究，所以本研究對透水混凝土做溫

度觀測試驗，並利用層集多重分類法進行分析

經過實驗結果顯示，熱影像在經過層集多重分類法後能有效將溫度性

質相近的像元隔成區塊，將溫度區塊邊界區分，進行數據分析，分析結果

顯示在保水層無包含水量下透水混凝土鋪面在日間受到日照及環境溫度影

響，升溫快速，平均溫度也比環境溫度高上許多，但到了夜間溫度差異逐

漸減少，熱輸出量降低與環境溫度達到平衡，而透水混凝土在保水層無含

水量狀態下溫度會略高於瀝青混凝土鋪面。

Pervious concrete is a special type of concrete with a high porosity, high

permeability, high volume of voids and rough surface. US Environmental

Protection Agency (EPA) suggests that an appropriate use of pervious concrete

is the best way to control initial rapid pollution and stormwater management.

The Agency determines limiting conditions of rainstorm runoff of all regions

and encourages the use of pervious concrete as road surface material. But in our

country, there are not enough systematic studies into the nature of pervious

concrete in local regions, especially the temperature changes caused by the

heated surface of pervious concrete. The present study contains therefore a

temperature observation test and an analysis using multi-layer classification.

According to the empirical results, through the multi-layer classification

of thermal imaging, the cells with a similar temperature could be efficiently

classified as a block. The data analysis was obtained on the basis of the

boundaries of temperature blocks. According to the analysis results, when its

water-retention layer contained no water, pervious concrete pavement was

heating up quickly because it was affected by the sunshine and the ambient

temperature during the day and its average temperature was much higher than

the ambient temperature; however, during the night, such difference was

gradually reduced and thermal output was reduced to reach equilibrium with the

ambient temperature. When the water-retention layer of pervious concrete

contained no water, its temperature would be slightly higher than the asphalt

concrete pavement.
