Comparsion and Harmonization of Skid Resistance Measuring Methods and Measurements on Pavement Surfaces

这项研究的目的是比较和协调不同测量方法对路面纹理和抗滑性能的测量。研究中使用的数据是1992年在比利时和西班牙进行的PLARC国际实验。该数据库已开放供研究人员使用。本研究试图对各种测量装置进行关联和协调，并提出将各种测量装置的测量值转换为通用的国际摩擦指数的模型。并将该指标应用于路面管理系统中。研究表明，不同测量仪器之间的相关性由测量原理、测量类型、测量速度和滑移率来确定。建立了防滑与织构关系的数学模型，并在此基础上提出了将不同仪器测量的防滑性能转换为统一尺度的国际摩擦指数(IFI)。尝试将IFI应用于路面管理系统。这项研究的结果将有助于协调(或标准化)许多国家使用的不同测量仪器的测量。

The objective of the study was to compare and harmonize texture and skid resistance measurements of pavement surfaces by various measuring methods. Data used in the study is the PLARC international experiment which was performed at Belgium and Spain in 1992. The database was opened to use for researchers. It was attempt in the study torelate and to harmonize the various measuring devices, and to propose the model for converting the measurement value by various device into the common scale (International Friction Index). It was also attempt to apply the index to pavement management system.It was shown in the study that the correlation among various measuring devices were determined by measuring principles, by types of measuring type, by measuring speeds and by slip ratios. The model relating the skid resistance and texture was developed and the International Friction Index (IFI) which can convert the skid resistance measurement by different devices into the common scale was proposed based on the developed model. It was attempted to apply the IFI to pavement management system. The results of the study would contribute to harmonize (or standardize) the measurements by different measuring devices in use in many countries.
