台灣地理位置位處亞熱帶，高溫多雨，鋪築多孔隙瀝青混凝土(porous asphalt concrete，PAC)，可降低行車打滑與水花飛濺的現象，在多孔隙瀝青混凝土使用量增加下，維修部分的問題也更加受到重視。冷拌瀝青混凝土(cold-mix asphalt，CMA）又稱為常溫瀝青混凝土，冷拌瀝青混凝土可在拌合出廠後，用袋裝於室溫下儲存，做為道路養護單位隨時運送至現場進行路面緊急搶修。
本研究首先探討3種不同冷拌多孔隙瀝青混凝土配比設計方法，由穩定值試驗結果得知，交通部「公路工程施工規範」方式所配置之冷拌試體，有較高強度且符合現地情況。研究參考冷熱拌密級配在規範上之差異，藉由熱拌多孔隙瀝青混凝土試驗項目，建立冷拌多孔隙瀝青混凝土規範。並探討冷拌多孔隙瀝青混凝土在泡水後，工程性質強度變化，由試驗結果得知不同冷拌瀝青，在泡水情形下，有不同強度損失情況。在現地試驗中，本研究使用Clegg土壤衝擊試驗機來獲得現地鋪面之Clegg衝擊值(Clegg Impact Value，CIV)，評估現地中不同瀝青種類及不同結構類型在Clegg衝擊值上差異，由數據結果得知較高強度之瀝青種類及結構類型，顯示出較高之Clegg衝擊值。

Due to Taiwan's geographical location and subtropical climate with high rainfall, paving porous asphalt concrete (Porous Asphalt Concrete, PAC) is used to reduce skid and puddle splashes. Regular maintenance is not required with the increase usage of porous asphalt concrete. Cold mix asphalt concrete (Cold-Mix Asphalt, CMA), also known as room temperature asphalt concrete is a mix which used by the road maintenance unit as temporary pothole repairs. It needs to be stored at room temperature after leaving the factory.
We will research the 3 different porous asphalt concrete cold mix ratio design method where the outcome will determine the standard configuration of the cold mix specimens that is the most suitable for current road conditions. To establish the cold-mix asphalt concrete porous specifications, we will need to reference the porous asphalt concrete hot mix pilot projects. We need to also study the hot and cold mix of density gradation differences. By experimenting the cold mix asphalt concrete porous in damp condition, the result shows that the engineering properties of intensity varies from different experimental results. The cold-mix asphalt under various damp conditions produces variable intensity losses. On another note, the Clegg Soil Impact Tester is also conducted to get the current to the pavement Clegg Impact Value (Clegg Impact Value, CIV). The study is used to assess the way different asphalt types and different structure types reacts and produces different Clegg impact value. Apart from that, the result also shows that higher strength of asphalt known type and structure type shows higher Clegg impact value.
