Study on Test and Influence of Anti-shear Strength of Asphalt Mixture

In order to further reveal the shear property of asphalt mixtures, shear device self-developed was used to research the variation and impact factor of anti-shear strength, cohesion and internal friction angle of different asphalt mixture types. The results show that: Modified asphalt can effectively improve the cohesion and anti-shear strength, but little effect on the internal friction angle; the internal friction angle and anti-shear strength of SAC-16 are greater than AC-16, but the cohesion is not significant different; with the nominal size of stone increased, the internal friction angle and anti-shear strength of asphalt mixtures rose, but little change in the cohesion; with temperatures increased, the anti-shear strength and cohesion of asphalt mixtures reduced gradually, but little change in the internal friction angle.
