摘要
用热光弹性法研究了半刚性基层沥青路面低温收缩裂缝的稳定性问题 .结果表明 :路面结构产生裂缝后 ,温度梯度是引起裂缝继续扩展的重要因素 .
The crack caused by thermal stress in asphalt concrete pavement was investigated by the photo_elastic method. The results show that the thermal load is the main factor causing the crack to develop continuously. The findings are in full agreement with those obtained by the finite element method.
