Statewide survey of skid resistances continued in 1978 with the testing of 2,943 miles (4,736 km) of state primary roads and 2,405 miles (3,870 km) of state secondary roads. About 10 percent of both the state primary mileage and the state secondary mileage had an average skid number of 28 or less. These pavements, in pariticular, should be considered for de-slicking.
In 1977 and 1978, 35 percent of the mileage of rural, state-maintained roads in Kentucky were surveyed. These roads carried 87 percent of all traffic on rural, state-maintained roads.
