Skid Tester Correlation Study
A correlation study was conducted between the California Skid Tester and an ASTM Skid Tester. Coefficients of friction were obtained with the California unit at the standard test conditions of locked wheel, smooth tire, wet pavement and a speed of 50 miles per hour. Skid numbers were obtained with the ASTM Skid Trailer operating at ASTM E274-65T standard test conditions of locked wheel, ribbed tire, wet pavement and a speed of 40 miles per hour. The ASTM unit made additional tests with the spee parameter changed to 50 miles per hour. Tests were also made by the ASTM unit with the ribbed tire replaced by a smooth tire at speeds of 40 and 50 miles per hour. For the four test conditions investigated, correlations were obtained that indicate that the California coefficient of friction can be used to estimate the ASTM skid number. (Author)
