台灣氣候高溫多雨，瀝青路面受水侵害剝脫的現象頻繁發生，瀝青混凝土中常以水泥作為填充料，以達到抵抗剝脫的效果，但水泥價格較高，且對環境負荷較大，近年來有研究參照水泥混凝土的作法，以水淬高爐石粉取代水泥，期望達到降低成本及碳排放量之效果，但其勢必會造成性質上的差異，而此差異是否處於工程上所能承受的範圍，還須經過實際試驗，分析試驗結果才能得知。
本研究使用馬歇爾試驗，來檢測使用水淬高爐石粉取代水泥做為填充料時，對於瀝青混凝土穩定值、流度值、間接張力與滯留強度的影響，並透過Superpave IDT試驗以及IDEAL CT試驗評估其對密級配瀝青混凝土的疲勞開裂性能的影響，其中，爐石粉採用100級、120級兩種，實驗溫度本研究則採用Superpave IDT試驗規範中建議之10℃以及IDEAL CT試驗規範中建議之25℃，共兩種溫度來進行實驗。
根據試驗結果，馬歇爾試驗數值皆符合規範之要求；兩種間接張力試驗之試驗結果趨勢相同，在10℃的試驗中120級爐石粉的配比抗開裂能力最佳，水泥之配比次之，100級爐石粉配比之抗開裂性質與水泥差異不大，25℃的試驗中100級爐石粉的配比抗開裂能力最佳，120級爐石粉的配比次之，由此可知，以抗開裂性質判斷，水淬高爐石粉取代水泥是可行的。從兩個試驗之結果得出結論，試驗的選擇依照需求，若是需要較準確且穩定的數據，建議使用Superpave IDT試驗，若是需要快速判斷抗開裂性質之趨勢，則可使用IDEAL CT試驗。

Due to the hot-and-rainy climate, stripping is one of the most common damage on asphalt pavement in Taiwan. Cement is often used as an alternative filler as well as anti-stripping agent in asphalt concrete. However, the price of cement is higher and the environmental load is greater than mineral fillers. Previous studies refers to the practice of cement concrete, which replaces cement with grounded granulated blast furnace slag (GGBFS), to reduce costs and carbon emissions by cement. However, it will inevitably cause qualitative differences. There is a need to test and analyze the effects of replacing cement by GGBFS in asphalt concrete.
In this study, the Marshall test was used to evaluate the influence of GGBFS as a filler in dense grade asphalt concrete (DGAC). Testing items include the strength stability value, flow value, indirect tensile strength, and strength retention rate. Furthermore, the Superpave IDT test and IDEAL CT test were used to evaluate the anti-cracking performance of DGSC. The activity indexes of the ground granular blast furnace slag are 100 and 120. The testing temperature for Superpave IDT and IDEAL CT test are 10°C and 25°C.
According to the test results, the Marshall test values meet all the specification requirements. As for the Superpave IDT and IDEAL CT tests, the results show the same trend. In the tests at 10℃, the 120-grade GGBFS has the best anti-cracking ability, followed by cement. The crack resistance of 100-grade GGBFS is not much different from cement. At 25℃, the 100-grade GGBFS had the best anti-cracking ability, and the 120-grade GGBFS was the second. From the perspective of crack resistance, it is feasible to replace cement with ground granular blast furnace slag. From the results of the two cracking tests, it can be concluded that the choice of test is based on needs. If more accurate and stable data is needed, it is recommended to use the Superpave IDT test. IDEAL CT test is recommended when the cracking resistance has to be evaluated in a quicker and simpler way.
