摘    要:通过直剪试验并结合理论计算对沥青路面微表处的抗剪性能进行研究,研究表明:夏李高温时,微表处的抗剪强度可以抵抗极端不利条件下的车轮剪切力;在最佳油石比±1%的范围内,微表处抗剪强度不会随油石比的增加而减小;界面污染或界面有水会减小微袁处与旧路面的粘结力.

关 键 词:微表处  抗剪强度  粘聚力  内摩擦角  界面

Abstract:This paper studies micro-surfacing shear performance of asphalt pavement via direst shear test in combination with theoretical calculation, and study shows that micro-surfacing shear strength at high temperature in summer can resist wheel shear force under extreme adverse conditions, and will not decrease with increase of asphalt-aggregate ratio within optimal asphalt-aggregate ratio ±1% range; while interface pollution or water on interface will reduce binding force between micro-surfacing and old pavement.
Keywords:micro-surfacing  shear strength  cohesion  internal friction angle  interface
