| Summary: | 碩士 === 國立中央大學 === 土木工程研究所 === 90 === We took AC-20, AR-8000, PMA, and high-viscosity asphalt(HiAsph) as the factors of the asphalt. Without adding to Hiasph, mineral fibers(MF) were added. Besides, cellulose fibers(CF) were added to PMA for comparing the effects of different fibers. The VFA period was on 5.0%~5.5%(total mix) and prepared for marshell samples and mastics. We took the upper one of the period for the design oil content.
Comparing the mastic rheology and performance of the Specimans, we could conclude that δ was not only highly correlated with the work of IDT, and creep modulus, but also nearly highly correlated with IDT, TSR, and MR. By the way, the correlation of G*/sinδ and depth of the wheeling rutting test was high.
The results of our study presented, we suggest that we could replace the speciman’s performance with the mastic rheology for determination of designing drainage asphalt. Addtionally, we could make a proper design method in local of Taiwan.
