環境保護已成為交通運輸中日益重要的問題，尤其是瀝青製造產業。儘管熱拌瀝青混凝土 (HMA)仍然為廣泛應用，但目前溫拌瀝青混凝土 (WMA) 技術研究指出，採用沸石技術能夠有效的降低瀝青混合料的產製溫度。本研究目的為評估應用沸石的流變特性和成效試驗。應用沸石與瀝青 AC 20 混合後之質量損失率、發泡效果、黏度和動態剪切流變儀 (DSR) 進行評估; 另外，成效試驗評估應用之 WMA 和 HMA 皆由實驗室進行，包括壓實性能指數、抗水分敏感性和漢堡輪跡試驗 (HWTT)。實驗結果顯示應用沸石材料相較於採用一般的瀝青黏度與溫度方法，使用壓實性能指數作為決定WMA的拌和與壓實溫度較為適合。其中，Aspha-min 具有比其他沸石更好的壓實性能指數。然而，依據抗水分敏感性和 HWTT結果顯示，天然沸石優於其他沸石，其抗水分侵害殘餘指數 (TSR) 為91%，10,000 次的車轍深度為 7.03 mm。依據本研究對於經濟、能源和環境影響分析結果，沸石對於環境有效益的，沸石可用作一種有效且可持續的 WMA 添加劑。

Environmental protection is an increasing and essential issue in pavement engineering, especially asphalt concrete manufacturing. Hot Mix Asphalt (HMA) is widely used worldwide. However, Warm Mix Asphalt (WMA) technology can decrease asphalt mixtures production and laying temperature. Zeolite is a material that can be a warm mix additive because it can provide a foaming effect to increase workability. This study evaluates zeolite as a warm mix additive in rheological properties, mixing performance, economic, energy, and environmental impacts. Four different types of zeolites, Aspha-min, Zp-4a, Type A, and Natural are used in this study. The optimized content of zeolite was determined by using a mass loss test, the foaming effect, viscosity, and Dynamic Shear Rheometer (DSR) were conducted to evaluate the physical properties of the asphalt binder. The results showed that using 5% of zeolite as an additive has better workability and viscosity. To understand the performances of WMA with zeolites, compactability indices, moisture sensitivity, and the Hamburg Wheel Tracking Test (HWTT) were also conducted. Experimental findings have shown that the compactability index can better determine mixing and compaction temperatures than viscosity tests for zeolite material as a WMA additive. The results showed that Aspha-min has better compactability indices than other zeolites, and Natural zeolite has lower moisture sensitivity and HWTT. With a Tensile Strength Ratio (TSR) of 91% and rut depth at 10,000 passes is 7.03 mm. Moreover, economic, energy, and environmental impact analyses have shown that zeolites are environmentally efficient. Reducing 15 °C and 30 °C can reduce energy consumption and GHG emission by 5.49% and 10.97%, respectively. This study found that zeolite may be used as an effective and sustainable WMA additive.
