Investigation of Friction Life Cycles for Indiana Pavements. Executive Summary
The report describes a review of INDOT's Friction Equipment calibration procedures and documents changes made as a result of the study. A new air-bearing force plate calibration pit was constructed and different axle sensors were adopted. Data from 11 years of correlations with the Area Reference Skid Measuring System (ARSMS) at the Transportation Research Center in Ohio and for 3 years on test pads at the INDOT Test Road was used to evaluate calibration procedures. A low-end friction pad was constructed as part of the study. Friction data collected over 5 years for 7 pavement surface types on 164 pavement sections is analyzed to develop prediction equations for friction life. A general model was selected as the best prediction for bituminous pavements, with an 2 of 0.48. Recommendations on the suitability of various pavement surface types are made for different levels of traffic. These recommendations were adopted into INDOT surfacing specifications.
