摘要
对沥青混凝土桥面铺装层进行剪切试验,并模拟了实际中的几种工况。通过对试件变形、应力及应变的分析,找出了引起桥面铺装层剪切破坏的主要原因。依据试件剪切破坏的过程,提出了疲劳破坏的控制条件。最后对试验误差进行了分析。
The paper makes shear experiment of pavement layer of asphalt concrete deck and simulates a few of real behaviors. By way of deformation, stress and strain of the sample, it find principal reasons failing the shear of deck pavement layer. In accordance with process of failure of sample shearing, the paper presents yet the conditions for control of fatigue failure. Lastly, it analyzes experimental error as well
