路面平整度是评价路面使用性能最主要的一项指标。根据目前国内外道路平整度研究现状,本文通过论证,选定采用能较全面反映道路不平整特性的国际通用的平整度指标(IRI)作为标准指标和国内通用的简单快速的平整度测量仪(XLPY—D型路面平整度仪)。经试验分析,提出了平整度仪测定指标转换为标准平整度指标的计算方法,并建立了我国规范平整度指标与标准平整度指标间的相关关系,为规范指标向标准平整度指标过渡和替换提供了可行的途径和方法。
Pavement roughness is to evaluate the pavement performance is the most important indicator. According to the current research status of road roughness at home and abroad, through the demonstration, the paper chooses the international common flatness index (IRI) which can fully reflect the unevenness of the road as the standard indicator and the simple and quick flatness measuring instrument XLPY-D-type road surface roughness meter). Based on the experimental analysis, this paper puts forward the calculation method of converting flatness index into standard flatness index, and establishes the correlation between normalized flatness index and standard flatness index in our country, in order to standardize the transition from standard flatness index to standard flatness index Provides a feasible way and method.
