沥青路面面层回弹弯沉值地设计与检测姚永鹤王艳红曹燕君（浙江广厦建设职业技术学院建筑工程学院 , 浙江东阳 322100 ）摘要： 回弹弯沉值是沥青路面公路工程设计和检测地重要指标, 我们结合实例阐述沥青路面面层弯沉设计值地计算、非标准轴载和标准轴载下弯沉实测值之间地换算、工程现场弯沉检测值地修正以及对弯沉检测工程地评定进行了理论分析, 为具体地工程实践提供了切实可行地参考依据.关键词： 沥青路面回弹弯沉设计值检测值Bituminous Pavement Road SurfaceSnapping Back Deflection Value Design and Examination Yao Yonghe, Wang yanhon (Architectural Engineering Dept. Guangsha College of Applied Construction Technology, Dongyang 322100,Zhejiang) Abstract: The snapping back deflection value was the bituminous pavement highway engineering design and the examination important target, this article unifies the example to elaborate the bituminous pavement deflection design value's computation, under the non-standard axle load and the standard axle load between the deflection actual value's conversion, the project scene deflection examination value's revision, as well as has carried on the theoretical analysis and the discussion to the deflection examination project's evaluation, has provided the practical and feasible reference for the concrete project practice.
