On the backgrounds of researches inside and outside country, and cooperating experiments with theories analyses, the influence of different processing technology parameters and different sbs modifier sorts on the sbs modified asphalts " properties has been studied. at the same time, their microstructure are observed through fluorescence optical microscopy and scanning electronic microscopy, thus to direct modified asphalt production. on the above conclusion ' s basement, analysing some disadvantages of the storage stability test of sbs modified asphalt in the current specification, a new storage stability test apparatus is developed
本文在參考國內外研究的基礎上,採用理論、試驗相結合的方法,研究加工工藝參數以及改性劑種類等對sbs改性
瀝青性能的影響,並通過熒光顯微鏡、掃描電鏡分析其微觀形態,從而指導sbs改性
瀝青的生產;在此基礎上,分析我國現行規范用來評價sbs改性
瀝青儲存穩定性方面的不足,開發了新的試驗儀,根據
動態剪切流變試驗結果和微觀狀態分析,提出一個新的指標? ?離析率r _ s來評價sbs改性
瀝青的儲存穩定性;最後,針對不穩定的改性
瀝青提出改善措施,研究證明摻加增容劑和穩定劑是行之有效的方法。
