中文摘要 | 本研究在瀝青混凝土中添加纖維或纖維與FCC粉體觸媒混合物,進行馬歇爾穩定 值、間接張力強度及疲勞試驗,求得疲勞生命期之預估方程式,以供柔性路面設計及服務期 限預估之用,並求得最適合之纖維或纖維與 FCC 粉體觸媒混合物之添加量。 研究結果,添 加纖維或纖維混合粉體觸媒之瀝青混凝土,其穩定值皆低於純瀝青混凝土;但間接張力強度 及疲勞特性大致較純瀝青混凝土佳, 若以此特性來選擇較適合之配比, 以採用瀝青含量 6 %及纖維添加量 0.2 %(對瀝青混合料重之比)或瀝青含量 6 %及纖維混合粉體觸媒添加 量 0.4 %(對瀝青混合料重之比)兩種配比較佳。 |
英文摘要 | The objective of this paper was to study the characteristics of asphalt concrete mixtures adding the fibers and fluid cracking catalyster. This study included the Marshall stability tests, indirect tensile tests, and flexural fatigue tests to predict the fatigue life of asphalt concrete, to provide the parameters for flexible pavement design, and to evaluate the service life of pavement. The results of this study indicated that the Marshall stability was lower for the asphalt concrete mixtures adding the fibers and FCC, but the indirect tensile strength and fatigue resistance was better. The best way to utilize the fibers and FCC as an asphalt modifier was adding 0.2% fibers by weight of mixtures or 0.4% fibers and FCC by weight of mixtures at 6% asphalt content. |
