This report presents some data obtained from testing twenty-two different types of overlays on three concentric tracks at the G. A. Riedesel Pavement Testing Facility at Washington State University. Six different passenger winter tires were tested, including unstudded, a garnet dust snow retread, and four different types of studs. The data represents a testing period from November 20, 1972 to February 20, 1973 and a total 300,000 revolutions, that is 900,000 wheel applications on the inside track and 300,000 wheel applications on the outside track.
The results reveal that the different polymer concretes show the least wear, and that rubber additives improved the performance of some of the asphalt concrete overlays. The type #2 stud continually showed less wear than the other types of studs. Comparisons with the previous ring revealed that the present ring overlays showed less wear, and that stud protrusions are much less. A comparison and discussion of the results from both rings at this wheel application range is presented. The results from the present data are also discussed. The results are tentative and may change as the present test continues.
