Kentucky Transportation Center Research Report
Since 1969, when a research-type, skid-test trailer was acquired, U.S. routes were surveyed in 1970 and 1971, and the interstate and toll road systems were surveyed in 1971. The data were used for research purposes and have been reported. The interstate and toll road systems were surveyed again for research purposes in 1974. Since October 1974, surveys have been performed under a highway safety project grant. All primary and principal secondary roads, involving 4,612 miles (7425 km), were surveyed in 1975. The 1974 and 1975 surveys, data reported herein, represented 25 percent of the mileage of rural, state-maintained roads in …
Accidents On Rural, Two-Lane Roads And Their Relation To Pavement Friction [Nov. 1976], Rolands L. Rizenbergs, James L. Burchett, Larry A. Warren
Accidents On Rural, Two-Lane Roads And Their Relation To Pavement Friction [Nov. 1976], Rolands L. Rizenbergs, James L. Burchett, Larry A. Warren
Kentucky Transportation Center Research Report
Friction measurements were made with a skid trailer at 40 mph (18 m/s) on 1460 miles (2350 km) of rural, two-lane roads (US routes) in Kentucky. Maintenance sections or subsections were treated as test sections. Accident experience, friction measurements, traffic volumes, and other available data were obtained for each. Various expressions of wet-pavement accidents and pavement friction were related and analyzed. Averaging methods were used in developing trends and minimizing scatter. A moving average for progressively-ordered sets of ten test sections and test sections grouped by Skid Numbers and Peak Slip Numbers yielded more definite results. The expression of accident …
