摘要

泡沫瀝青製程具有節省能源及降低污染的環保優勢，為最近幾年歐美積極研究採用的路面再生工法。本研究在實驗室執行泡沫瀝青混合料的配比設計試驗，並將設計拌製的泡沫瀝青試體與熱拌再生瀝青試體進行工程性質比較。研究結果顯示添加80%舊路面刨除料的泡沫瀝青混合料，最佳瀝青用量由全新材料用量的3.5%降至2.0%，且抗水份侵害能力也較全新材料佳，充份顯示泡沫瀝青工法採用高刨除料添加量的好處。在回彈模數及疲勞試驗數據上，則顯示泡沫瀝青具有與傳統熱拌再生瀝青混合料相競爭的可能性。

Using a Wirtgen WLB10 laboratory plant, works were performed on local materials to produce foamed bitumen treated cold mixtures. The engineering properties of foamed bitumen treated mixes are investigated and compared with those of hot recycled asphalt. Test results show the benefits of utilising high percentages (80%) of milled asphalt in foamed bitumen mixes. The optimum bitumen content can be reduced from 3.5% to 2.0% compared to mixes consisting of all new aggregate, and the moisture resistance of the mixture is enhanced. Resilience modulus and fatigue data show that foamed bitumen treated mix performs as well as hot mix asphalt.
