asphalt modifier
解釋
瀝青改性劑-
The paper is based on innumerable practical heavy - load road data, deliberate heavy - load standard in detail through theoretical arithmetic, and bring heavy - load standard about cement concrete pavement and asphalt concrete pavement separately ; in the meantime, through a large quantity of cement concrete pavement stress calculation, the paper puts forward relation expression between load on concrete board and stress level under board ; meanwhile, the paper puts forward traffic classification about cement concrete pavement and asphalt concrete pavement ; through bearing board testing on each structure sheaf the paper finds the material modulus gets modified ; through comparing position equivalent rebound modulus to theoretical equivalent rebound modulus, the paper points out limitation of nomograph in course of cement concrete pavement design, whereby, puts forward modifier formulas about theoretical equivalent modulus
本文以大量的重載道路資料為主，從實際出發，結合理論計算，對重載標準進行了詳細的討論，分別給出了水泥混凝土路面與瀝青混凝土路面的重載標準了；同時，通過大量的水泥混凝土板底應力計算，推導出了混凝土面板荷載與板底應力水平的關系式；給出了水泥混凝土路面與瀝青混凝土路面的交通分級；通過對試驗路各結構層進行承載板測試，發現現有材料模量較以前有了明顯的提高；對比現場實測的當量回彈模量與理論當量回彈模量，指出現有水泥路面設計中的諾謨圖不能完全符合現有道路材料，從而提出了對理論模量的修正公式。 -
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。 -
