中文摘要 | 本研究使用五種瀝青進行試驗,藉以建立瀝青混凝土與瀝青之性質的關係。每種瀝青分別製作馬歇爾試體,並施予不同的養治狀況,以研究熱、紫外線、空氣和自然日照對瀝青硬化所造成的影響。利用回彈模數試驗和間接張力試驗進行評估馬歇爾試體之老化影響。然後從混凝土中回數瀝清,分別試驗回收瀝青與原始瀝青,以評估老化的效應。另外,自兩處鋪設路段鑽心取樣,再將瀝表回收以評估瀝青稠度及其紅外線光譜的特徵。藉由變異數分析及迴歸分析決定試驗參數的顯著性,並建立參數間的關聯。比較不同老化程序的效應,進而建立試驗室老化與現地老化的關係。 |
英文摘要 | Five asphalts were used in a laboratory testing program to establish a relationship between mixture properties and the binder properties. Each of thses five asphalts was used to make Marshall specimens in the asphalt mixture testing program. The compacted specimens were subjected to different exposure conditions to study the effects of heat, ultraviolet light, air and natural sunlight to the hardening of asphalts. All the aged Marshall specimens were evaluated by the resilient modulus and indirect tensile tests at 5 and 25℃. Asphalt residues were recovered from the asphalt mixtures, and tests were performed on the recovered asphalt residues and the original asphalts to evaluate the effects of age hardening. Also, core samples and recovered asphalt residues from two paving projects at various ages were evaluated for consistency and infrared spectral characteristics. Analyses of variance and regression analyses were performed on the results to determine the significance of test parameters and to establish relationships. The effects of different artificial aging processes were compared. Relationships between laboratory aging and field aging were established. |
