Abstract: Reflective cracking is a distress which influences the performance of semi-rigid pavement. In this paper, based on studies and investigations of reflective cracking of semi-rigid pavement, the idea of using high quality granular base as sandwich layer to ervent semi-rigid pavement from reflective cracking is developed .

Key words: reflective cracking, resistance cracking performance, semi-rigid pavement, granular base

摘要： 半刚性基层沥青路面反射裂缝是影响其使用功能的主要病害, 在综述国内外半刚性基层沥青路面防治反射裂缝措施及研究现状的基础上, 重点提出了采用高质量级配碎石中间层防止和减缓半刚性路面反射裂缝的研究思路及其途径, 以供进一步研究参考.
