XLPY-D型路面平整度仪与国际平整度指数(IRI)

XLPY-D VIALOG AND INTERAHNTIONAL ROUGHNESS INDEX

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。

The road roughness is an important index evaluating pavement performance. On the basis of the resarch on the pavement roughness at home and abroad, the International Road Roughness Index (IRI) is regarded as a standard index and the vialog XLPY-D is selected and applied.. The former can reflect the feature of the road roughness and the latter is a current、simple and rapid apparatus measuring roughness in nation. Through surveying and analyzing certain roads, the computing method changing the measure index into IRI is put forward and the relationship transforming National Rorghness Index (NRI)into standard Roughness Index(SRI) is carred out,thus providing the transformation from NRI into SRI with the feasible measurement.
