沥青路面芯样评价指标养护设计中的应用
The Application of Core’s Evaluation Index Systems in the Asphalt Pavement Maintains & Design
摘要:
沥青路面芯样评价指标体系可对路面的结构厚度、病害范围和集料级配组成、沥青关键指标的变化进行检测和分析,通过对路面芯样的抗压强度、抗剪切性能和层间粘结力等力学指标进行检测,分析路面使用状况,深入了解路面病害程度和发展趋势,解析病害产生原因,并纠正常规上的认识误区,为设计方案提供科学的依据。
Abstract: Adopting the core’s evaluation index systems, we can know and analyze the structural thickness, the disease range and the material grade of the road, as well as the change of the key index of bitumens. Through the compression strength, resisting and shearing mechanics indexes such as bonding strength, etc., we can understand the disease intensity of road surface and development trend in depth, analyze the reason of the disease, and correct the understanding mistaken idea on the routine, to offer the scientific basis for design.
