Skid Number-Speed Gradient Testing in Colorado
This Interim Report covers the Colorado Division of Highways investigation of skid resistance deterioration as test speeds are increased. Tests were made on one Portland Cement test site and on nineteen samples of the four most frequently applied asphaltic friction courses provided for in Colorado Specifications. These tests produced evidence that skid resistance measured on Colorado Type A Open Graded Plant Mix Seal Coats deteriorated to a significantly lesser degree than any of the other four pavements. Type A PMSC also produced the highest absolute skid resistance values. Further monitoring of the test sites is necessary to determine the rate of degradation of the pavement surfaces due to time, weather, and traffic.
