得出了隨膠粉含量的增加膠粉改性瀝青的抗老化性能提高，老化后低溫延度比減小、質量損失量減小、軟化點提高，針入度呈正態分佈及改性瀝青老化的規律，提出了廢膠粉用作瀝青改性劑時粒徑選擇和摻量確定的原則，為廢膠粉改性瀝青在公路瀝青路面中的應用提供了良好的技術支持。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。Needle penetration of petroleum waxes, method of test for 05. 01, 15. 09
