Statewide Survey of Skid Resistances of Pavements (1976)

Statewide survey of skid resistance continued in 1976 with testing of rural, major, collector roads (1985 Functional Classification). This included 5,074 miles (8,166 km) of state secondary roads and 788 miles (1,268 km) of rural secondary roads. About 17 percent of the secondary mileage and about 15 percent of the rural secondary mileage surveyed in 1976 may be considered slippery. A small percentage of both secondary (5.3 percent) and rural secondary (5.8 percent) roads had an average skid number below 26. These sections, in particular, should be flagged for deslicking. Through 1976, 50 percent of the mileage of rural, state-maintained roads in Kentucky were surveyed. These roadways carried 93 percent of all traffic on rural, state-maintained roads
