Studies of pavement skid resistance in Kentucky have been in progress since 1956. In 1964, an extensive investigation into the use of an automobile as a testing tool was undertaken and an interim standard method of testwas selected. Since then, investigations with the device have continued, both to facilitate meaningful interpretation of skid-test data and to evaluate the skid resistance performance of pavement surfaces. Variables associated with the testing device, procedures and pavement surfaces were investigated. Several paving projects were tested to determine the number of sites required to obtain a representative result. The polishing of pavements due to traffic, time in service, and year-to-year climatic differences were considered in order to ascertain the frictional characteristics of various pavements. Every type of pavement, sealing, and deslicking treatment used on Kentucky's state road system were monitored and assessed as to their frictional properties. The skid resistance of bituminous and portland cement concrete pavements were related to cumulative traffic. (Author)
