| 摘 要： | 半刚性沥青路面反射裂缝产生的原因之一是半刚性基层温度变化引起的，半刚性基层和沥青面层之间加入柔性基层可有效地防止沥青路面出现反射裂缝，根据传热学原理，采用有限单元法对吉林通化试验路3种路面结构半刚性基层顶部温度状况进行了对比，分析结果表明无论夏季或冬季，柔性基层都能有效地改善沥青路面半刚性基层的温度状况，从而减少或消除沥青路面出现反射裂缝．

| Abstract: | Reflecting cracks of semi-rigid asphalt pavement is caused by semi-rigid base temperature change. Flexible base between semi-rigid base and asphalt surface could efficiently avoid or reduce reflecting cracks of asphalt pavement. According to heat exchange theory, temperature status of semi-rigid base top in Jilin Tonghua test road which has three kinds of pavement structures was contrasted by applying finite element method. The result indicated that flexible base could efficiently ameliorate temperature status of semi-rigid base of asphalt pavement, therefore could reduce or avoid reflecting cracks of asphalt pavement. |
