摘要

由於天然資源日趨枯竭，為了維護環境生態並確保人類社會經濟的永續發展，未來營建工程所使用之材料勢必朝節能化及再生化方向發展。台灣地區天然砂石料源開發已面臨短缺之瓶頸。成長快速且大量生產的汽車工業，為環境帶來重大的衝擊，廢輪胎因為體積大、不易腐化、有易燃性，處理不易。台灣地區位於亞熱帶多雨的地區，密級配瀝青混凝土已漸漸無法滿足服務需求，路面因水分入侵，在天雨過後路面轍推擠、坑洞、剝脫等損壞情形亦常見，使得造成路面維修頻繁，增加養護費用支出，因此藉由採用廢輪胎橡膠瀝青混凝土（CRM），嘗試鋪設以瞭解其成效性。
本研究由廢輪胎橡膠瀝青混凝土之配合設計結果進行試驗室及現地作各項成效試驗，其與密級配瀝青混凝土、再生瀝青混凝土的馬歇爾試體及密級配瀝青混凝土鑽心試體比較。由回彈模數試驗結果，現地鑽心試體試驗結果分析，顯示廢輪胎橡膠瀝青混凝土較一般密級配不易產生龜裂。浸水殘餘強度（TSR）試驗結果，顯示出廢輪胎橡膠瀝青混凝土有較好之抗水性質，在台灣多雨的氣候環境下，能有較好的之成效性質等。
本研究針對於廢輪胎橡膠瀝青混凝土，在現地鋪設經由定期成效檢測，瞭解其鋪設後之路面成效性，進行路面服務成效評估。並利用成本分析方式、分析廢輪胎橡膠瀝青混凝土與密級配、再生及改質瀝青混凝土之經濟性，以供國內道路養護參考之用。

In virtue of nature resources has downwardly drain away, in order to prevent our ecological system and meanwhile to ensure the sustainable development of humanity.
For the future, the materials use in construction engineering should become more ecological and become friendly for our environment.
Nowadays, the exploration of sandstones resources in our country has become complicated problem to be solved. A burgeon of automobile industries has gave a significant effects for our environment. For example: a lots number of waste tires from our vehicles, it’s a need a great budget to solved this waste tires and long period is need to perfectly corrupt this waste tires.
Taiwan is located at the subtropical zone and has rainy climate, for pavement engineering, OGAC (Open Grade Asphalt Concrete) can’t unable to satisfy the demand of service ability for pavement engineering target. Because of the climate factors, rainy bring a lots of water and this water will invade in to the pavement gradually, for the consequence our pavement will lose their functions.
For the result we should maintenance the pavement often in a short time，for the consequence we must increasing fees of maintenance this pavement. In order to reform function of OGAC pavement I would like to introduce Asphalt-Rubber Hot mix Concrete Pavement and to replace OGAC pavement with Asphalt-Rubber Hot mix Concrete Pavement is my majority target.
In this paper I would like to compare by the results of Asphalt-Rubber Hot mix Concrete Pavement in job site with the results of OGAC Pavement and Reclaimed Asphalt Pavement (RAP) that made by Marshall’s in Laboratory.
From the result of Modulus Resistant (MR) test that made in laboratory, we could see that Asphalt-Rubber Hot mix Concrete Pavement has a better performance than OGAC Pavement. And also from the result of Tensile Strength Ratio (TSR) from laboratory, we could see that Asphalt-Rubber Hot mix Concrete Pavement has a better function to resist water that immerse into our pavement than OGAC Pavement.
By this paper, I would like to explain from the observation in long period I’ve made making “service ability” analysis from this Asphalt-Rubber Hot mix Concrete Pavement. And also use cost analysis making comparison between Asphalt-Rubber Hot mix Concrete Pavement with OGAC Pavement and also Reclaimed Asphalt Pavement (RAP).
