Title: OPERATIONAL GUIDELINES FOR LONGITUDINAL PAVEMENT PROFILE MEASUREMENT
Accession Number: 00791546
Record Type: Monograph
Abstract: This digest provides road profiler operators, their supervisors, the users of road profiler output, and interested engineers and administrators practical details about the workings and operation of various road profilers. It differentiates between the data requirements for computing the International Roughness Index (IRI) and the Ride Number (RN). It addresses the several areas that can affect proper data collection: the equipment, the shape of the surface being measured, the measurement environment, the profiler operations, and the profiler operator skill requirements. These operational guidelines are based on the determination of factors that affect roughness measurements, the quantification of the effect of these factors on repeatability and accuracy, and the determination of how and when these factors can be controlled. This digest presents the project findings in the form of guidelines for "best practices"; more technical presentations of the research findings are contained in the companion publication, NCHRP Report 434, "Guidelines for Longitudinal Pavement Profile Measurement."
