廢棄輪胎橡膠粉之應用為鋪面材料研究者所關注的議題，因為此涉及資源再生與工程績效，然而，目前橡膠瀝青規範亦僅限在基本物性作為初估分類，且對瀝青黏結料的力學特性尚無完整的預測模式，更甚鋪面於服務壽命內瀝青混凝土適用規範之健全性，瞭解該材料以因應交通負荷和氣候變化的影響，為一值得深究探研的範疇領域。本研究選用通過No.30號篩橡膠膠粉作為瀝青改質劑，並對黏結料進行基本物性試驗及韌性試驗，結果顯示橡膠提升基底瀝青的軟化點、黏滯度與回彈率，並會降低針入度與感溫性。然而，瀝青黏結料的老化有可能會導致柔性路面的耐久性喪失，且攸關疲勞開裂、永久變形等潛藏危害，係鋪面設計上不容忽視且至關重要之材料性能，故本研究針對橡膠瀝青混凝土進行新鮮、短期老化及長期老化等三類不同狀態，並變更試驗的溫度、加載速率以探討該材料之物理、力學試驗，再以一般密級配瀝青混凝土作為對照，其結果顯示瀝青性質之於混合料存在程度上的關聯性，間接張力值結果可知橡膠瀝青混凝土較一般瀝青混凝土具低感溫性，於老化經過後亦呈現穩定趨勢；破壞應變則以橡膠瀝青混凝土整體較一般瀝混凝土高，其展現之延展特性更為良好；破壞應變能為材料於最大破壞點前載重－變形曲線涵蓋面積，橡膠瀝青混凝土具一定程度下降，並產生與間接張力值相關之趨勢變化；韌性性質則為橡膠瀝青混凝土高於一般瀝青混凝土，顯示添加橡膠改質瀝青混凝土之延展變形要較後者顯著。綜觀上述橡膠瀝青混凝土其在中溫狀態時，因黏結料內含橡膠顆粒，使能擁有足夠的韌性行為以抵抗開裂破壞；反之在高溫狀態時，因橡膠改質促使瀝青感溫性為不敏感，故在高溫時會較一般瀝青混凝土更穩定，對於長期鋪面服務績效有利，同時老化時間的長短之於橡膠瀝青混凝土在各項數值可見趨勢較為穩定且平緩。

The application of waste tire rubber powder is an issue of concern for paving material researchers. There is involved in resource recycling and engineering performance. Currently, the specification of asphalt rubber binder is also limited to basic physical properties. There is not a complete prediction model for the mechanical properties of asphalt binders and neither the specifications for asphalt concrete in service. In this study, crumb rubber powder was used as asphalt modifier, and physical property test and toughness test were carried out on the asphalt-rubber binders. The empirical test results showed that the performance of penetration, softening point, viscosity, elastic recovery, and temperature-susceptibility were improved by rubberized modification. However, aging of asphalt binder may result in loss of durability of the pavements. The pavement deterioration such as fatigue cracking and permanent deformation should not be negligible and important material properties in paving design. In this study, rubberized asphalt concrete was subjected to three different types of conditions: unaging, short-term aging and long-term aging. The temperature and loading rate of the test were varied to investigate the physical and mechanical tests of the material. In addition, the dense-grade asphalt concrete was used as a control mix. The results show that the asphalt binder properties are related to the mixture. The results of indirect tension values show that rubberized asphalt concrete has lower temperature sensitivity than conventional asphalt concrete, and it also shows a stable trend after aging. The failure strain is higher for rubberized asphalt concrete than conventional concrete, indicating that the ruberized asphalt has better ductility. Additionally, the failure strain energy is the area of the load-deformation curve before the maximum failure point, and the value of the rubberized asphalt concrete decreases, resulting in a trend related to the indirect tension value. The toughness property is higher for rubberized asphalt concrete than conventional asphalt concrete. Therefore, rubberized asphalt concrete has sufficient toughness to resist cracking damage due to the rubber particles presenting in the binder at intermediate temperatures. It is beneficial to long-term pavement performance.
