Description
This report documents the development and preparation for implementation of a specification for using International Roughness Index, using an inertial profiler, as a smoothness measure for new portland cement concrete pavements in Minnesota. This new specification represents a departure from the use of the Profile Index, using a California Profilometer, for concrete pavement smoothness. In addition to providing recommendations to the Minnesota Department of Transportation regarding the implementation of the specification, the report contains additional information and analyses. These include a summary of the specifications in use by other states for measurement and incentive/disincentive payment for concrete pavement smoothness, an analysis of the effects of pavement surface characteristics on the International Roughness Index and the Profile Index, and a comparison of IRI-based concrete pavement smoothness specifications in use by other states. The report concludes with several recommendations for the new specification and for its administration and enforcement by the Minnesota Department of Transportation.
