For many years, aggregates for use in new road surfacings have been selected according to their ability to resist polishing, as measured by their Polished Stone Value (PSV). However, traffic has increased dramatically since the original research, and experience has suggested that expected performance is not always achieved in practice. This report gives the results of a study to predict skidding resistance from PSO and traffic data.
