摘要
总结了旧水泥混凝土路面沥青加铺层反射裂缝的产生机理与寿命预测研究现状,重点讨论了当前国内外沥青加铺层反射裂缝的防治措施、试验评价方法及存在的问题,并展望了其研究趋势。在重载交通条件下沥青加铺层反射裂缝防治技术及简单易行、可靠适用的反射裂缝试验设备与方法是当前研究的方向与重点。
The generation mechanism and fatigue life prediction on reflection cracking of asphalt overlay on old concrete pavement are presented. The open issues, preventive measures and testing methods at home and abroad are discussed in detail. It is concluded that under heavy transportation loads, technologies for prevention of reflection cracking of asphalt overlay and the simple, feasible testing equipment and methods are the research direction and focus.
