4.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.
研究结果表明：集料级配和公称最大集料粒径对沥青混合料抗剪强度有显著的影响；沥青混合料抗剪强度受其集料中针片状含量的影响较大，集料中针片状含量增大，沥青混合料抗剪强度减小；结合料的性质，特别是针入度、软化点和粘度对沥青混合料抗剪强度有较大的影响，随着针入度减小，软化点和粘度增大，沥青混合料抗剪强度增大；含油量对沥青混合料抗剪强度有较大影响，随着油石比的增大，沥青混合料抗剪强度减小；沥青混合料抗剪强度受其空隙率的影响较大，一般随着空隙率的增大，其抗剪强度减小；沥青混合料均匀性与沥青混合料抗剪强度绝对数值间没有明显的关联，而与数值间的变异性有着很好的相关性。
