Inertial and inclinometer based profiler repeatability and accuracy using the IRI model

Oregon DOT is transitioning to use the International Roughness Index (IRI) for an incentive\disincentive program for pavement smoothness evaluation for newly paved roads. The IRI will typically be determined by contractors using inertial profilers. This research evaluated the procedures, site, and equipment used for establishing a reference profile for a certification process for inertial profilers. In a comparison of several profiling devices, the inclinometer-based profiler used by Oregon DOT for the reference profile showed sufficient results in repeatability and accuracy in profile measurement and calculation of IRI. However, the certification site shows significant variability in IRI across the site, which can lead to lower accuracy scores when the exact path is not followed. Further, significant differences in IRI were observed during repeat visits throughout the course of the study period.
