基于沥青路面剩余寿命指标的养护路段划分方法探讨

Discussion on maintenance section division method based on the residual life index of asphalt pavement

路面使用性能评价是科学养护的基础,而路段划分的精确与否则直接影响了路面使用性能的评价。文章利用吐-乌-大高速公路多项检测数据,在分析规范推荐的养护路段划分方法存在缺陷的基础上,引入剩余寿命指标来补充、完善现有路面评价体系,建立了基于沥青路面剩余寿命指标的养护路段划分方法,并利用该方法对实例进行了分析和对比论证。

Pavement performance evaluation is the foundation of scientific maintenance, and section dividing accurate or not directly affect the pavement performance evaluation. Using a number of testing data of Turpan - Urumqi - Dahuangshan highway, on the basis of the analysis of specification recommended maintenance sections divided method has defects, introducing the residual life indicators to complement and perfect the existing pavement evaluation system, set up the maintenance section classification method based on the residual life index of asphalt pavement, and using the method conduct analyze and compare on the instance.
