Functional thresholds for designmaintenance of urban pavements: Functional criteria for sustainable design of urban pavements

摘要

Functional criteria have been mostly defined in urban pavements using subjective methods, rather than by means of objective and repeatable procedures. The WholeBody Vibration, the Heart Rate Variability, and new technologies to determine theIRI (International Roughness Index), are nowadays available. For that, an analysis ofavailable technologies is made under a PC-O (Pavements Clients-Oriented) integralperspective, including simulations with the HDM-4 computer program. The IRIcriteria for speeds allowed on urban roadways, i.e. the so-called IRIcity criteria, areproposed in the paper.
