瀝青混凝土配合設計中,在計算篩分析與級配曲線時,都有所規範的上限與下限,唯有在填充料的部分僅規範通過 # 200篩達70%以上,然而對於更高的通過比例甚至是100%通過之填充料粒徑並沒有詳加的說明 ; 而由於填充料可改變瀝青膠泥流動性,形成溫感性低、黏度大的瀝青膠漿,故此因素可能會對瀝青膠漿或是瀝青混凝土產生不同程度的影響。
本研究探討不同粒徑之石粉填充料對瀝青混凝土工程性質的影響,並針對瀝青與不同粒徑填充料混合後的膠漿做流變黏彈性質分析比較。
綜合工程試驗結果來看,馬歇爾穩定值流度值、間接張力與回彈模數試驗上,並沒有顯著的差異表現。然而在滯留強度上,可以發現隨著填充料粒徑的增加,滯留強度表現越佳。另外在Cantabro磨耗試驗中,可以得知隨著粒徑的增加,磨耗值也會有越大的表現。
而在流變試驗當中,可以發現抗車轍能力與粒徑大小呈現正相關而與抗疲勞能力呈現負相關。
In marshall mix design, the calculation of gradation curve have a standard upper and lower limits, only in the filler specification have the rule that through the # 200 sieve more than 70%, but for a higher proportion even 100% of the filler particle size is not described in detail; and because the filler material can change the flow of asphalt, the formation of lower temperature sensitivity and lower viscosity, so the factors may influence at varying degrees.
In this study, we will discuss the effects of different fillers particle size on the engineering properties, and the effects on viscoelastic properties of asphalt mixed with different particle size fillers.
According to the results of the comprehensive engineering properties, there is no significant difference in the Marshall stability, the indirect tension and the resilient modulus. However, in the retained strength, it can be found that as the filler particle size increases, the retained strength will have better performance. Also in the Cantabro test, it can be learned that as the particle size increases, the wear value will increase.
In the rheological test, we can find that the anti-rutting ability and the size of the particle size is positively correlated, however the anti-fatigue ability to show a negative correlation.
