• Abstract:
  The Indiana Department of Transportation (INDOT) is currently utilizing a profilograph and the profile index for measuring smoothness ; assurance for newly constructed pavements. However, there are benefits to implementing a new IRI based smoothness specification ; utilizing road profiles measured using inertial profilers. Technological advancements have improved the quality of road profiles ; measured using inertial profilers; furthermore, utilizing inertial profilers allows smoothness data to be collected much more quickly and ; efficiently than the methodology currently utilized by INDOT. Pavement smoothness quantified using International Roughness Index (IRI) ; calculated using profiles provided by inertial profiles is better correlated to user response than what is currently being utilized by INDOT. ; Furthermore, INDOT currently utilizes IRI to monitor the pavement smoothness throughout the remaining life of the pavement. ; Consequently, Utilizing IRI for measuring the smoothness of newly constructed pavements allows seamless monitoring of pavement ; smoothness from cradle to grave. This study presents an IRI based draft smoothness specification for newly constructed pavements ; utilizing profiles provide by inertial profilers. The process developing a draft specification included developing pay factor tables, ; developing the methodology for calculating the smoothness bonus, developing methodology for locating areas of localized roughness, ; and developing inertial profiler certification procedures.
