Roughness-International Roughness Index
Roughness- reflects the pavement surface condition that directly affects vehicle
operating costs.
Roughness Definition.
The deviations of a pavement surface from a true planar surface with
characteristics dimensions that affect vehicle dynamics, ride quality, dynamic
loads, and drainage, for example, longitudinal profile, transverse profile, and
cross slope”
