回收瀝青混凝土(RAP)，具有永績發展的潛在效果，而國內現今少有改質瀝青混凝土回收料(RMAP)之研究。本研究使用RMAP之回收瀝青60℃黏度約為37,050 Poise，RAP之回收瀝青60℃黏度約為45,000 Poise，新鮮瀝青為AC-20，軟化劑為AC-10，再生劑為RA-5，且選擇新鮮瀝青AC-20之密級配瀝青混凝土作為對照組。回收料添加比例為10~100%，目標黏度依還原劑和回收料添加比例有所不同，配比設計採用相同的瀝青用量並盡量使級配曲線相近以進行工程性質與體積性質的比較。透過穩定值、流度值、間接張力、回彈模數試驗、滯留強度試驗和老化前後之Cantabro磨耗驗等試驗，評估對再生瀝青混凝土(RAC)和再生改質瀝青混凝土(RMAC)之影響。除了流度值，RMAC和RAC工程性質皆符合規範要求，且顯示回收料硬化存果仍在；RMAC與RAC之Cantabro磨耗率有顯著差異，試體短期老化與長期老化後之Cantabro磨耗率則無明顯差異。添加再生劑RA-5時，RMAC與RAC之V.M.A.隨著回收料比例增加而下降；但添加軟化劑時，RAC在高回收料添加比例情況下，由於孔隙率增大造成V.M.A.上升，而RMAC仍能控制在4%孔隙率，RMAC於回收料添加量少於60%時，由工程性質與體積性質結果來看，具用於鋪面之可行性。受黑石頭程度的影響，使用再生劑和高回收料添加比例60%~80%情況下，試體表面產生冒油和油斑。

There are few domestic studies of Reclaimed Modified Asphalt Pavement (RMAP) now. In this study, AC-20 and AC-10 were respectively used as virgin asphalt and softening agent. RA-5 was used as rejuvenating agent. In order to compare engineering and volumetric properties for different mix designs, asphalt content and grading curve of mix designs were adjusted to the same as much as possible. In this study, conducting Marshall test of stability, flow, indirect tension, resilient modulus, residual strength and Cantabro test with mixture conditioning to evaluate virgin asphalt concrete, Recycled Asphalt Concrete (RAC) and Recycled Modified Asphalt Concrete (RMAC). In addition to flow value, engineering properties of RMAC and RAC were all in compliance with specification requirements, and reclaimed materials still obviously had hardening effect. RAC and RMAC had significant differences in Cantabro test, but there were no significant differences between short-term aging and long-term aging. When adding rejuvenating agent RA-5, V.M.A. of RAC and RMAC would decline with the increase of the proportion of reclaimed materials；but when adding the softening agent, V.M.A of RAC in a high proportion of reclaimed material would rise due to porosity increasing, and RMAC would still control the porosity of 4%. From the results of engineering and volumetric properties, it is feasible to use RMAP in asphalt pavement when proportion of reclaimed materials are less than 60%. Because of the effect of black rock, the surface of specimens would generate binder spots and bleeding.
