• Abstract:
  The Ohio Department of Transportation (ODOT) has set strategic goals to improve driving safety by maintaining
  
  smooth pavement surfaces with high skid resistance. ODOT has taken the initiative to monitor pavement
  
  friction on Ohio roadways and remedy the pavement sections with low skid resistance. However, this is a
  
  passive and reactive approach toward the problem. A more proactive approach would be to test hot mix asphalt
  
  (HMA) in the laboratory during the mix design stage to ensure that the aggregates used will provide adequate
  
  friction over the life of the pavement. With the validity of a research-grade polishing machine established in a
  
  previous study, ODOT has initiated this project to conduct a long-term field study to collect field performance
  
  data over a longer time period. The research effort was aimed at further validating the applicability of the
  
  previously developed laboratory test protocol and acceptance criteria through a correlation and comparison
  
  study with long-term field performance data. This research has produced the following deliverables: (a) a new
  
  commercial grade accelerated polishing machine called “The Polisher,” (b) models for predicting the field
  
  performance of asphalt pavement friction under traffic, and (c) supplemental notes with draft specifications for
  
  polishing HMA samples and for testing friction properties. The commercial grade polishing machine and the
  
  supplemental notes were recommended for ODOT implementation.
