| 摘 要： | 利用单轴贯入试验对不同尺寸的沥青混合料试件进行了抗剪强度检测。结果表明，随着试件尺寸减小，抗剪强度偏差增大；抗剪强度与路面车辙深度有较好的对应关系。对于直径100mm的Ac-20中面层芯样，单轴贯入试验能较好地区分其抗车辙能力水平，是一种快速简便的检测方法。 |

| Abstract: | Uni-axial penetration test has been conducted to get shear strength of different size asphalt mixture specimens. The results show that shear strength error would increase with specimen size decreasing, shear strength has high correlation with rutting depth. For 100ram diameter AC-20 mixture samples, uni-axia] penetra- tion test can distinguish their rutting resistance level. It＇s a quick and easy method for detecting rutting disease. |
