摘要

過去台灣地區鋪面採用不透水之設計，使得大地喪失涵養水源之功能，且因都市化日漸之提升而減少原有植被地，雨水滲入機會大幅減少，
部分地區遇颱風或豪雨時產生淹水現象。
根據相關研究指出透水性鋪面(Permeable pavement)具有降低熱島效應之成效，本研究主要目的為探討透水性鋪面之熱學行為，於實驗室先行量測面層材料熱傳導係數，並於現地實驗區以簡易氣象站及溫度探測針進行現地氣象與鋪面溫度資料量測，以探討不同類型鋪面溫度變化之情形。
根據實驗分析結果影響鋪面溫度因子以日照及氣溫為最大，研究中建立之模型，發現面層熱傳導係數影響鋪面吸熱及散熱之速率，密級配瀝青混凝土白天於表面溫度雖較低，但其面層底部溫度卻較透水性鋪面為高，而透水性鋪面以透水連鎖磚面層底部溫度最低，各種鋪面平均熱輸出以密級配瀝青混凝土為最大，其次為透水瀝青混凝土，透水連鎖磚為最小，顯示面層材料除熱傳導係數影響外反射率亦影響鋪面吸收熱能之多寡，因此選擇較合適之透水性鋪面材料可降低都市中鋪面熱能儲存。

The pavement of Taiwan adopted the waterproof design in the past, made the earth lose the function which conserved the source of water, urbanize original vegetation improvement day by day reduce, rainwater permeate chance reduce by a wide margin, Some areas produced
and flooded water phenomenon while meeting typhoons or the torrential rain.
Point out the Permeable pavement according to relevant research have effect of reducing the tropical island effect, this main purpose of research, in order to probe into the calorifics behavior of the permeable pavement, one storey of materials heat-conduction coefficient that going ahead of the rest amount examines the surface in the laboratory, and on test block survey with weather station and temperature needle go on meteorological phenomena and pavement temperature materials amount examine now now, in order to probe
into the situation that the temperature of different kinds of pavements changes.
Influence the temperature factor of pavement to regard sunshine and temperature as biggest according to the experiment analysis result, model that set up, find surface layers of heat-conduction coefficient influence shop front heat absorption and speed that dispel the heat in studying, it is relatively low in surface temperature in the daytime that dense-graded asphalt concrete, but its temperature of bottom is higher than permeable pavement, and permeable interlock-brick with surface layer of bottom temperature most low, various kinds of pavement average to is it buy the asphalt concrete for being heaviest with security to output while being hot, permeable asphalt concrete completely secondly, permeable interlock-brick completely, show surface layers of material except that heat-conduction coefficient influence person who reflect influence shop front absorb number of heat energy also, so choose and can be reduced
in the city than the suitable permeable pavement material the heat energy of pavement stored.
