Available in PDF, EPUB and Kindle. Book excerpt: Road roughness is gaining increasing importance as an indicator of road condition, both in terms of pavement performance, and as a major determinant of road user costs. This paper defines roughness measurement systems hierachically into four groups, ranging from profilometric methods (2 groups), through response type road roughness measuring systems (RTRRMS's), and, subjective evaluation. The International Roughness Index (IRI) is defined, and the programs for it's calculation are provided. The IRI is based on simulation of the roughness response of a car travelling at 80 km/h. The report explains how all roughness measurements can be related to this scale, also when travelling at lower speeds than 80 km/h. The IRI emerges as a scale that can be used both for calibration and for comparative purposes.

Available in PDF, EPUB and Kindle. Book excerpt: The research project was conducted to evaluate the performance of an inexpensive non-contact roughness measuring device, Roughness Surveyor, as well as the potential use of this device as a calibration reference for Response-Type Road Roughness Measuring (RTRRM) systems. A correlation was also conducted between RTRRM systems from three different States (Georgia, Florida, and Minnesota) against the Roughness Surveyor, the inertial profilometer owned by the Ohio DOT, and the profilometer designed and operated by the South Dakota DOT. A total of sixteen test sites were selected for the correlation and calibration study with a total of 52 individual test sections encompassing a variety of roughness levels and pavement surface types.

Book excerpt: Volume I: Experimental Investigation, documents an extensive series of measurements of the performance of a commercial inertial road profiling system (IRPS) and a commercial response-type road roughness measurement (RTRRM) system. Based upon the results of these measurements and upon an analysis of the operation of such equipment, calibration and testing guides, given in the Volume II were developed to assist users in assessment of IRPS and RTRRM functionality and operating performance.
