摘要
沥青路面使用性能关键指标的临界范围是确定路面所处状态、选择路面养护时机的关键参数。针对高速公路沥青路面预防性养护时机问题,结合国内外研究成果及我国沥青路面实践,探讨并明确路面使用性能关键指标如路面状况指数(PCI)、平整度指数(IRI)、路面车辙(RD)、横向力系数(SFC)等的临界值范围,为我国高速公路管理部门选择沥青路面预防性养护时机提供参考。
The critical range of key indices of application performance of asphalt pavement is a key parameter for determining pavement status and selection of maintenance opportunity of pavement. In allusion to the problem of preventive maintenance opportunity of asphalt pavement of expressways and in combination with foreign research achievements and our national practices of asphalt pavement, this paper probes into and makes clear the range of critical values of key indices of pavement application performance such as pavement condition index （ PCI ） , international roughness index （ IRI ） , rut of pavement （ RD ） and side - way force coefficient （ SFC ） , etc. to provide a reference for our national expressway management departments to select preventive maintenance opportunity of asphalt pavement.
