Slipperiness of Highway Pavements. Phase I
A study evaluated the relationships between (1) pavement friction and test speed, (2) friction levels and traffic volume, and (3) friction levels and wet pavement accidents. It included correlation of friction measurement units and the establishment of 30 sites for long-range observation of friction levels. At 61 sites, stopping distance tests were performed so that a correlation could be established between values obtained with a two-wheel skid trailer and those obtained with a stopping-distance car. Regression analyses were performed on these sets of data. Data from 62 sites were used to establish the relationship between pavement friction and test speed. Forty-six sites were tested to determine the relationship between friction level and accumulated traffic volume. Non-polishing S-4 and S-5 bituminous mixes were observed for average PSDN after 25-30 million vehicle passes. Five hundred twenty-one sections on Virginia's Interstate system, totaling 312.8 miles, were studied to determine the relationship between the percent of wet accidents and predicted stopping-distance skid numbers.
