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.

Presents the first ever guide for vehicle scanning of the dynamic properties of bridges Written by the leading author on the subject of vehicle scanning method (VSM) for bridges, this book allows engineers to monitor every bridge of concern on a regular and routine basis, for the purpose of maintenance and damage detection. It includes a review of the existing literature on the topic and presents the basic concept of extracting bridge frequencies from a moving test vehicle fitted with vibration sensors. How road surface roughness affects the vehicle scanning method is considered and a finite element simulation is conducted to demonstrate how surface roughness affects the vehicle response. Case studies and experimental results are also included. Vehicle Scanning Method for Bridges covers an enhanced technique for extracting higher bridge frequencies. It examines the effect of road roughness on extraction of bridge frequencies, and looks at a dual vehicle technique for suppressing the effect of road roughness. A filtering technique for eliminating the effect of road roughness is also presented. In addition, the book covers the identification of bridge mode shapes, contact-point response for modal identification of bridges, and damage detection of bridges—all through the use of a moving test vehicle. The first book on vehicle scanning of the dynamic properties of bridges Written by the leading author on the subject Includes a state-of-the-art review of the existing works on the vehicle scanning method (VSM) Presents the basic concepts for extracting bridge frequencies from a moving test vehicle fitted with vibration sensors Includes case studies and experimental results The first book to fully cover scanning the dynamic properties of bridges with a vehicle, Vehicle Scanning Method for Bridges is an excellent resource for researchers and engineers working in civil engineering, including bridge engineering and structural health monitoring.

This handbook dicussess tyre-road contact forces generated by heavy vehicles covering their influence on road surface and bridge response and damage, as well as ways of regulating and improving vehicles so as to minimize road damage.;The main incentive for understanding vehicle-road interaction is the possibility of reducing the road damage caused by heavy vehicles and the very high associated costs. This may be achieved by highway authorities, through improved design and construction of roads; by government agencies, through regulations intended to encourage the use of more "road-friendly" vehicles; or by vehicle engineers, through design of improved vehicle configurations and suspensions, which minimize road damage.;The book provides a unified mechanistic approach to the entire subject, covering vehicle dynamics; dynamic tyre forces; weigh-in-motion; pavement and bridge response; damage mechanisms of paving materials; vehicle-guideway interaction; suspension design to minimize road damage; and assessing road damaging potential of vehicles for regulatory purposes. It includes 25 literature reviews, covering topics from asphalt deformation to weigh-in-motion, and citing over 500 references. In addition, it discusses both the fundamental mechanics of the mechanical and civil engineering systems, as well as practical and implementation issues.
