摘要
本文采用三维空间有限元力学模型,分析旧水泥混凝土路面上沥青加铺层产生反射裂缝的机理,探讨设置应力应变消散软夹层的阻裂效果,为改进在旧水泥混凝土路面上设计沥青加铺层的方法提供理论依据。
A three dimensional finite element analysis has been used to analyse the mechanism of reflective cracking in asphalt overlays on existing concrete pavements and to explore the effect of installing the stress and strain relieving interlayers on preventing reflective cracking. The analysis in the paper will provide a theoretical basis for improving the design of asphalt overlays on existing concrete pavements.
