由於國內交通運輸量隨著經濟發展日益漸增，鋪面道路的使用頻率隨之提高，其中瀝青混凝土係為鋪面材料使用之大宗，重要性不辯自明，但瀝青混凝土在生產過程中因為容易產生大量二氧化碳等溫室氣體，所以不利於環境之存續，為此，如能夠有效減少瀝青混凝土之製造或延長使用壽命，則能夠有效地減少溫室氣體之產生，因此如何判斷瀝青混凝土之疲勞壽命為上述問題之首要關鍵，故本研究以國外常用於探討疲勞性能表現之四點彎曲試驗(Four Point Bending Test, 4PBT)為主要之試驗方法，過程中係以固定頻率10Hz之應變控制加載模式在25°C下進行之，而間接拉伸破裂試驗（Indirect Tensile Asphalt Cracking Test, IDEAL-CT）則為輔助之靜態載重試驗方法，其試驗目的係在求得瀝青混凝土抗破裂指標CTindex，以評估路面抵抗破裂的能力，故為探討及了解瀝青混凝土本身抗破裂之能力與疲勞特性之關係，因此將4PBT與IDEAL-CT結果作為比較，並同時探討相互試驗間替代之可能性，以避免4PBT所需耗費的冗長時間成本；並以不同瀝青混凝土作為試驗標的，以了解不同瀝青混凝土間疲勞壽命之差異，而試驗過程中使用之瀝青混凝土分別為AC-20密級配、老化後之AC-20密級配及改質
IV-F型密級配，最後4PBT結果則分別以AASHTO T321-07提供之勁度50%分析法、AASHTO T321-17提供之峰值分析法，以及耗散能量分析法(Dissipated Energy Ratio, DER)進行分析及解釋，從分析結果中得以發現峰值分析法之相關係數為三者中最高，次之為勁度50%分析法，且勁度50%分析法與峰值分析法相比，疲勞壽命之結果較為保守，但並不適合用於分析改質IV-F型密級配之試驗結果，而耗散能量分析方法(DER)則因分析之結果多為缺漏，故難以推斷其適用性，最後，從4PBT與IDEAL-CT結果比較發現，兩者間具有一定程度之相關性。

As the traffic volume in Taiwan is increasing with the economic development, the amount of used asphalt concrete become more and more.However, it’s exactly that a larger amount of asphalt concrete which easily generate greenhouse gases during the production process make a great negative impact to the enviroment.Therefore, if we can effectively reduce the production of asphalt concrete or extend its service life, the negative impact to enviroment will decrease.Hence,how to determine the fatigue life of asphalt concrete is the primary key solution to the above problem.In this study,The Four Point Bending Test(4PBT) was used to determine the fatigue life of asphalt concrete, and the Indirect Tensile Asphalt Cracking Test(IDEAL-CT) was choosed to evaluate the resistance of the pavement to cracking as an auxiliary test. Therefore, in order to investigate and understand the relationship between cracking resistance and fatigue characteristics of asphalt mixtures, the results of 4PBT and IDEAL-CT were compared.In this study,three types of asphalt concrete were used as specimens to understand the difference in fatigue life between different asphalt concretes.Three types of asphalt concrete were AC-20 dense graded,aged AC-20 dense graded and modified IV-F dense graded separately.Finally, 4PBT results were analyzed and interpreted by the 50% stiffness analysis method provided by AASHTO T321-07, the peak analysis method provided by AASHTO T321-17 and the Dissipated Energy Ratio (DER) analysis method individually.It is found that the peak analysis method has the highest correlation coefficient among the three, followed by the 50% stiffness analysis method.The stiffness 50% analysis method has more conservative fatigue life results compared with the peak analysis method, but it is not suitable for analyzing the test results of modified IV-F dense graded. Finally, the comparison between the results of 4PBT and IDEAL-CT shows that there is a certain degree of correlation between them.
