老路拓宽工程因新老路基路面之间的不良结合和差异沉降易造成沥青路面结构产生纵向反射开裂,为了提高相应的抗裂能力,近年来在结合部沥青下面层和半刚性基层之间铺设 RoadMesh钢丝网加筋处治的新技术得到越来越多的应用.为此,依托实体工程,通过预设新老路面结合部纵向开裂,建立了合理的新老路面结合部加筋结构的三维有限元模型,根据不同荷位作用下沥青路面结构力学响应的数值模拟,确定了最不利荷位,并据此对比分析了 RoadMesh钢丝网、土工布、自粘式玻纤格栅和高强土工格栅加筋新老路面结合部的沥青路面结构力学响应.研究结果表明,荷载两车轮均作用在新路一侧且靠老路一侧的车轮外缘与结合部对应...

In the existing road widening projects, due to the poor joint and the differential settlement between new and existing pavement, it is easy to cause the producing longitudinal reflection cracking for asphalt pavement structure. In order to improve the correspond- ing crack resistance, a new technology of reinforcement and treatment in the joint is getting more and more applications for paving the RoadMesh steel mesh between the lower asphalt layer and the semi-rigid base layer in recent years. For this reason, relying on the practical project, ...
