溫拌瀝青混凝土應用於台灣地區可行性研究
A study of warm mix asphalt to be used in Taiwan
摘要
自工業革命以來全球化石燃料的使用不斷增加，成為主要能源的供應方式，導致溫室氣體不斷的排放造成地球暖化，因此節能減碳、永續經營及綠能發展概念成為現今主要議題，以熱拌及溫拌瀝青混凝土施工溫度、生產過程碳排放量及成效試驗三個構面進行研究與評估。 熱拌瀝青混凝土生產過程產生大量的煙霧及溫室氣體，對施工人員及氣候暖化造成嚴重的影響，若降低拌合溫度可有效改善相關問題，但須評估降低生產溫度是否對瀝青混凝土成效產生不良影響，本研究以添加劑方式調製溫拌瀝青膠泥藉此降低拌合溫度，針對溫拌瀝青膠泥性質進行相關性試驗，評估添加劑改變原始瀝青膠泥特性，探討溫拌瀝青混凝土配合設計方式；將以刨除料摻配量0%、20%、40%及60%配比設計，比較熱拌與溫拌瀝青拌合後之成效性質、材料及拌合過程中所產生碳排放量試算，並探討兩種瀝青混凝土成本差異。 藉由降低拌合溫度所生產之溫拌瀝青混凝土有較低的碳排放量，但須做更多的評估及規範的制定才能應用於台灣地區鋪面，並且溫拌拌合技術種類繁多，須有效掌控各種拌合特性，才可確保施工品質。

The usage of fossil fuel increasing from Industrial revolution and it becomes the main energy resource, but on the hand, fossil fuel results in global warming as well. Therefore, energy saving and carbon reduction, sustainable use, and environmental consciousness becomes the main theme for discussion. The present study investigates on three aspects. First, estimate the degree of warm mix asphalt and hot mix asphalt during the procedure. Second, estimate at carbon reduce emissions while processing asphalt pavement. Finally,the asphalt concrete effectiveness of the test. The processing of hot mix asphalt usually hazy with smoke and result in greenhouse effect, moreover, it will influence the health of worker as well as climate serious negative effect. Hence, this research assumes that decreasing the temperature of during operation can avoid negative effects. The present study use an additive to manufacture the warm mix asphalt in order to decrease the temperature, moreover, this research aim at the additive character of warm mix asphalt . This study with the mix design practices, this is, 0%, 20%, 40 and 60 % RAP to compare the HMA and WMA carbon emissions, cost differences and effectiveness of the test results. The result of this experiment confirms that decreasing asphalt mix temperature can reduce carbon emission. Nevertheless, knowing well characteristics of blending and evaluating condition risk before application are the most important aspec.
