In accordance to the defects presented in using the chinese road asphalt technical standards to assess the asphalt performance as well as the facts that the shrp test equipment of usa can not be widely employed in china since its being very expensive, the shrp rheological concept is utilized in the research project to carry out the exploration of the rheological properties of modified and non - modified asphalt by using conventional tests such as penetration and ductility. the conclusions obtained by using the conventional test rheological index to assess asphalt performance are compared with those by using the shrp rheological index and their certain correlation are found
針對目前我國道路石油瀝青技術標準評價瀝青路用性能存在的種種缺陷，以及美國shrp試驗設備因其昂貴性而暫時無法在國內大量推廣應用這一事實，本課題試圖利用shrp流變思想，採用針入度、延度等常規試驗設備進行改性及非改性瀝青流變特性的研究，並將常規試驗流變指標評價瀝青路用性能的結論與shrp流變指標評價結論作比較，找出它們之間的相關關系，從而肯定了採用常規試驗設備進行瀝青流變特性及路用性能研究的有效性。 -
The research results show that aggregate gradation and the nominal maximum aggregate size evidently influence the shear resistance of asphalt mixture ; aggregate flakiness content influences the shear resistance of asphalt mixture, and with the increase of aggregate flakiness content the shear resistance of asphalt mixture decreases ; asphalt binder properties, especially penetration, softening point and viscosity influence the shear resistance of asphalt mixture, and the latter increases with the decrease of penetration and the increase of softening point and viscosity ; asphalt content influences shear resistance of asphalt mixture, and with the increase of binder / aggregate ratio the shear resistance of asphalt mixture decreases ; air void influences shear resistance of asphalt mixture, and usually with the increase of air void the shear resistance of asphalt mixture decreases ; homogeneity does not have a direct and obvious relationship with absolute value of shear resistance of asphalt mixture, but does with variation of shear resistance of asphalt mixture
研究結果表明：集料級配和公稱最大集料粒徑對瀝青混合料抗剪強度有顯著的影響；瀝青混合料抗剪強度受其集料中針片狀含量的影響較大，集料中針片狀含量增大，瀝青混合料抗剪強度減小；結合料的性質，特別是針入度、軟化點和粘度對瀝青混合料抗剪強度有較大的影響，隨著針入度減小，軟化點和粘度增大，瀝青混合料抗剪強度增大；含油量對瀝青混合料抗剪強度有較大影響，隨著油石比的增大，瀝青混合料抗剪強度減小；瀝青混合料抗剪強度受其空隙率的影響較大，一般隨著空隙率的增大，其抗剪強度減小；瀝青混合料均勻性與瀝青混合料抗剪強度絕對數值間沒有明顯的關聯，而與數值間的變異性有著很好的相關性。 -
