摘要: 利用斜面剪切仪对沥青混合料进行剪切试验,调节剪切仪剪切刃的间距,可以得出压头压力标准差和变异系 数均最小的最佳剪切刃间距,进而计算出沥青混合料的最大抗剪强度,并用单轴贯入试验对比了最大抗剪强度结 果的准确性。结果表明,斜面剪切试验可以准确地测定沥青混合料的最大抗剪强度。其试验方法简单可行,可以 在沥青混合料剪切试验中推广应用。

Abstract: Using inclined plane shear instrument to carry out the shear test of asphalt mixture, the best shear blade pitch in minimum of the standard deviation and coefficient of" variation can be got by adjusting the edge pitch of blades. And then the biggest shear strength of asphalt mixture is obtained, furthermore, the accuracy of the results is verified by uni-axial penetration test. The results show that the inclined plane shear test can accurately determine the largest shear strength of asphalt mixture. Its testing method is simple and feasible, and it can be applied and promoted in the shear test of asphalt mixture.

Key words: asphalt mixture , shear strength , shearing , inclined plane shear ;
