瀝青回收料(Reclaimed Asphalt Pavement , RAP)近年來越來越廣泛的應用於道路當中，在環保意識的推動下，各國也開始添加各種比例的回收料於路面當中，在國內早有實際應用的例子，然而，回收料的品質及來源難掌握，在配比設計階段也僅能簡單得到瀝青黏度及針入度數據，實難控制添加RAP於新鮮瀝青混凝土後的鋪面績效，應對RAP有更深入了解，才能適材適用。本研究分為老化瀝青及回收料兩部分作為探討，瀝青包括回收瀝青(RB)以及添加1%MⅢ之回收瀝青(RBM)，探討及基本物性及流變行為，了解到添加了MⅢ瀝青後其彈性恢復、抗疲勞性增加，抗車轍性下降。另一方面製作100%RAP回收料製作瀝青混凝土試體，透過三種溫度150℃、170℃及180℃及乾濕狀況之力學試驗比較，找出回收料最佳拌合溫度為167.5±2.5℃。為探討老化瀝青有效反應量將新鮮粒料與回收瀝青重新拌合製作試體，利用溫度與CT Index兩者的比值所作的回歸方程式，找出最佳拌合溫度下的最大瀝青激活量約為23%。最後，將混合料之車轍、肯特堡及CT Index乾濕結果製作三軸績效平衡圖，建立回收料的最佳績效範圍，最後，定義出了RAP在3軸圖的績效範圍，並了解到在167.5±2.5℃的拌合溫度下其激活量約為23%。

In the world , the pavement is widely utilized as Reclaimed Asphalt Pavement (RAP) in recent years. Environmental protection is the main idea in pavement , many countries want to add various recycled materials in pavement. There have been some examples are used in their road. However, the quality and source of recycled materials are difficult to control. Viscosity and penetration is too easily to caculate in the design progress so that is not enough to discribed the pavement performance. RAP must do more experiment that can use in pavement. This research is divided into two parts: bitumen and asphalt. Bitumen including Recycled Bitumen (RB) and recycled bitumen added 1% MⅢ(RBM). Discussing the basic physical properties and rheological behavior. The elasticity , recovery and fatigue resistance increase, and rutting resistance decreases. On the other hand, asphalt concrete were made by100% RAP recycled materials. Through the comparison of mechanical tests at three temperatures of 150°C, 170°C and 180°C in dry and wet conditions, the best mixing temperature of the recycled materials was found where is 167.5±2.5°C. In order to explore the dgree of activity, using naturel aggregate blending with RB and RBM to make asphalt concrete. Using the regression equation of the ratio between the temperature and the CT Index, the maximum degree of activaty amount of asphalt at the optimal mixing temperature was found approximately 23% . Finally, make a three-axis performance balance chart based on the rutting、cantanbro and CT Index, the wet and dry results to establish the best performance of the recycled materials.Above of all , RAP the best of performance was define by 3-D performance diagrams and it has 23% of bitumen in 167.5±2.5℃.
