回收瀝青混凝土(RAP)具有經濟價值和減少資源浪費之意義，本研究採用拌和場兩種不同老化程度之回收瀝青混凝土作為研究材料，分別為RAP-0.6 (回收瀝青60℃黏度約為600,000 poise)與RAP-1.6 (回收瀝青60℃黏度約為1,600,000 poise)，再生劑為RA5、RA75和軟化劑為AC-10與AC-5，並選擇添加AC-20新鮮瀝青之密級配瀝青混凝土作為對照組。
以不同含量(0%、20%、40%、60%)之回收料添加還原劑(RA5、RA75、AC5、AC10)，將目標黏度設定為2000±400 poise，再將瀝青混凝土回收料添加入AC-20基底瀝青與新鮮粒料中拌和，形成再生瀝青混凝土(RAC)。評估添加不同種類的還原劑對RAC之影響，進行穩定值、流度值、間接張力、回彈模數試驗、殘餘強度試驗、車轍輪跡試驗，並探討不同擴散天數之間接張力變化，最後將萃取RAC之瀝青進行黏度、FT-IR、GPC，探討黏結料之物理、化學性質。
在配合設計流程上因還原劑用量視為瀝青含油量之一部分，在RAP添加比例較高時，使用還原劑會出現過多瀝青現象。當RAP添加比例較高時，會降低其RAC之粒料間孔隙(V.M.A.)；同時，也會造成瀝青填充率(V.F.A.)增加的情形，可能形成冒油。拌合過程應選擇中黏度的再生劑(RA75)做使用，可和回收瀝青有較好的拌合效果，同時也提升對抵抗水侵害的能力。績效試驗結果顯示回彈模數與間接張力顯示添加RA75之RAC結果優於其他兩者，因黏度較高，與RAP材料黏度較相近，融合效果較佳；化性試驗結果顯示FT-IR結果顯示酮官能基指標隨著添加RAP越多有上升的趨勢；亞砜官能基則隨RAP添加比例增加而上升，說明了添加RAP越多，老化官能基也較明顯。

Reclaimed asphalt pavement (RAP) has economical value and can reduce the consumption of resources. In this thesis, RAP of two different aged level are used as the research materials, which are RAP-0.6 (viscosity 600,000 poise under 60℃) and RAP-1.6 (viscosity 1,600,000 poise under 60℃). The rejuvenating agents are RA5 and RA75. The softening agents are AC-10 and AC-5. The control group is the dense-graded asphalt concrete with AC-20.
Different levels of RAP (0%, 20%, 40%, and 60%) are added to the recycled agents (RA5, RA75, AC5, and AC10) with target viscosity being 2000±400 poise. Then the recycled asphalt concrete (RAC) is formed by mixing the base asphalt AC-20 and fresh aggregates. To evaluate the characteristics of RAC with different recycled agent, the following tests are conducted: stability test, flow test, indirect tension test, resilient modulus test, tensile strength ratio, and track test. The relationship between indirect tension and diffusion time is also discussed. Finally, the physical and chemical properties of asphalt binder extracted from RAC are discussed.
Because the recycled agent is considered as a part of the asphalt content, using the recycled agent with high RAP ratio will lead to the negative asphalt content and decrease the voids in the mineral aggregate (V.M.A). In the meanwhile, the voids filled with asphalt (V.F.A) will also increase, which may cause bleeding. In RAP mixing process, the recycled agent with medium viscosity (RA75) should be chosen in order to obtain better mixing effect and higher resistant to moisture damage. The performance test results show that the RAC adding with RA75 are better than other counterparts in resilient modulus and indirect tension strength. Because RA75 has higher viscosity which is close to RAP’s, the mixing effect is better. Finally, FT-IR result shows that the content of the aged functional group (ketone index and sulfoxide index) increases with the increment of RAP content.
