台灣因人口、工廠的數量大增,隨之產生的廢機油數量不計其數,加上環保意識高漲,若能將過剩的廢機油作為再生劑添入老化瀝青中,即可減少其他天然材料的使用,朝永續經營方向發展。本研究以實驗室方法模擬瀝青長短期老化,再以廢機油添加於老化瀝青作為再生劑,藉由各項工程性質和流變試驗等,分析廢機油對不同老化瀝青的膠漿性質影響,評估廢機油作為再生劑之可行性。
綜合試驗結果,添加廢機油於老化瀝青對AC-10、AC-20及改質Ⅰ型瀝青都有顯著的再生效果。基本工程性質試驗如軟化點、黏度等,三種瀝青加入廢機油再生後都可恢復至與初始狀態相近,且符合規範要求。韌性試驗方面,各再生瀝青韌性幾乎都低於原始瀝青數值,顯示廢機油對老化瀝青韌性值恢復效果有限。DSR結果顯示,傳統瀝青經廢機油再生後抗變形能力皆較原始狀態差,但改質Ⅰ型瀝青不論長短期老化,形成再生瀝青後其抗變形能力都比原始狀態佳,抗車轍能力上升。最後由擴散試驗得知,廢機油的擴散能力對於三種瀝青的再生皆有明顯效果,且擴散速率隨著溫度提高。
整體來看本研究的試驗結果,廢機油作為再生劑應用於老化瀝青為可行的,且對SBS改質瀝青有更好的再生效果。
This research is investigated to use waste engine oil as rejuvenating agent in aged asphalt binder. In this research, the instrument Rolling Thin Film Oven is used to simulate aged process. Then waste engine oil is added to aged asphalt binder. There are several experiments to evaluate the properties of aged asphalt binder containing waste engine oil.
From all the test results, we could sort out that waste engine oil can be applied as rejuvenating agent. For both conventional asphalt and modified asphalt, there are no significant difference on mechanical properties and all of results are qualified. What’s more, this research also compared waste engine oil with standard rejuvenating agent RA5 in order to measure the diffusion ability of waste engine oil. It shows that waste engine oil can diffuse well in aged asphalt binder. According to the results, using waste engine oil as rejuvenating agent is feasible in the future.
