• 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.
