半刚性基层沥青混凝土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 ,半刚性基层和沥青混凝土面层之间加入柔性过渡层可有效地防止沥青混凝土路面出现反射裂缝。根据传热学原理 ,采用有限单元法对吉林省通化试验路 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 ,柔性过渡层都能有效地改善沥青混凝土路面半刚性基层的温度状况 ,从而减少或消除沥青混凝土路面出现反射裂缝
Semi-rigid base asphalt concrete pavement reflection cracks is one of the reasons is the semi-rigid basement temperature changes caused by the semi-rigid base layer and asphalt concrete surface layer of flexible transition layer can effectively prevent the reflection of asphalt pavement cracks. According to the principle of heat transfer, the finite element method was used to analyze the temperature of top of semi-rigid basement of the three pavement structures of Tonghua Experimental Road in Jilin Province. The results show that the flexible transitional layer can effectively improve the asphalt pavement half Rigid grass-roots temperature conditions, thereby reducing or eliminating the reflective cracking of asphalt pavement
