近年來，每年產生數以萬計之瀝青路面刨除料（Reclaimed Asphalt Pavement, RAP），衍生各種環保及工程管理問題，我國因應循環經濟及節能減碳，積極推動「再生再利用粒料循環運用於公共工程」政策，解決刨除料堆置問題之同時也達到永續經營發展，然而，時常為了節省成本而忽略考量 RAP 材料性質直接地大量使用，導致路面鋪築後短時間內容易出現劣化行為。本研究導入 RAP 老化瀝青之有效反應量概念，利用間接張力開裂試驗（IDEAL-CT）、間接張力強度試驗（IDT）、馬歇爾穩定值試驗、車轍輪跡試驗結果，探討瀝青混凝土於不同 RAP 含量之疲勞開裂與車轍績效性能，並藉由績效平衡設計方法評估最適切再生瀝青混凝土配比設計，提高再生鋪面之耐久性。根據試驗結果顯示，當添加 RAP 含量較少時（20%、30%），再生瀝青混合物性能表現相對 0% RAP 實驗對照組之變化不大；然而，當 RAP 含量高於40% 時，再生瀝青混凝土之疲勞開裂相關試驗與車轍試驗結果都受到嚴重的影響，且兩特性皆對新鮮瀝青添加量極為敏感的情形下，容易造成再生瀝青混合物開裂能力極佳而車轍表現極差或是相反之極端表現，為此本研究透過適當之 RAP 有效反應量假設，明顯能在兩項性能之間取得較佳的平衡，除此之外，為了避免瀝青混凝土在高含量 RAP 使用下出現較嚴重之疲勞開裂行為，必須訂定有效反應量假設之上限值；此外，從 IDEAL-CT 試驗與車轍試驗之績效平衡設計結果顯示，當再生瀝青混凝土擁有較佳之抗開裂性能時，抗車轍能力則會相對較差，也藉由比較 IDT 試驗與車轍試驗績效平衡結果，顯示輪跡試驗之動穩定值相對於最終車轍深度，更能有效評估 RAP 使用量與有效反應量對再生瀝青混凝土車轍性能之影響。

Currently, million tons of RAP (reclaimed asphalt pavement) are produced every year which leads to many environmental and engineering management issues. In Taiwan, the government promoted a policy, which is called “re-using recycled aggregates in public works”, to solve the RAP stockpile and keeping problems, and to achieve sustainable development goals. However, adding high contents of RAP to new mixtures without considering its properties for saving time and money always caused premature deteriorations of the new asphalt pavement. In this study, the concept of DoA (degree of aged binder activity) was considered for the recycled asphalt mix design process. The Indirect Tensile Asphalt Cracking Test (IDEAL-CT), Marshall Stability test, and wheel tracking test were conducted to assess the cracking and rutting resistance of recycled asphalt mixtures with different RAP contents. The performance balanced concept was applied to evaluate the most appropriate mix design in order to improve the performance of recycled asphalt mixtures. The experimental results indicated that adding more than 40% RAP would adversely make both cracking and rutting performance be more sensitive to the virgin asphalt content. These results also suggested that there should be upper and lower limits of virgin asphalt content to achieve a better performance-balanced design. It is found that the incorporation of a hypothesized appropriate DoA could help achieve a better balanced-performance. In addition, the result showed the better the cracking resistance of recycled asphalt concrete is, the lower the rutting resistance will be.
