Functional criteria for sustainable design of urban pavements

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