沥青路面专用剪切仪的开发与试验研究

Study on Test and Development of Shear Apparatus for Asphalt Pavement

沥青路面的面层和基层之间有粘结层，而粘结层的剪切强度可以作为评定路面粘结层的指标之一。本文详细介绍了沥青路面专用剪切仪的结构及工作原理，并通过现场试验来计算其剪切强度，认为该仪器可有效地检测沥青路面层间的剪切强度，从而可以检测施工质量。

There is bonding layer between surface layer and the grass - roots level of asphalt pavement, and the shear strength of the bonding layer can be used as one of targets for assessment of the bonding layer. This paper describes the structure and working principle of special shearing device for asphalt pavement and the shear strength by caculation in field trials, and also presents the shear apparatus is so effective in testing layer of asphalt pavement between the shear intensity that it can be used to test the construction quality.
