The report describes the validation of models previously developed to normalize pavement friction measurements to standard environmental and operational conditions. In addition, recommendations are reported to improve the techniques and equipment for pavement friction measurement. Two models were examined for normalization of weather-related and seasonal variation of pavement friction. Their performance was found to be comparable, but the generalized prediction model is more readily applied than the mechanistic model, which requires knowledge of the percent normalized gradient of the pavements to be adjusted. Two recommendations are made for improving pavement friction measurement equipment and techniques. The first suggests the use of current equipment with both smooth-treaded and ribbed standard test tires. The second requires modification to the equipment but provides for simpler instrumentation in that it is possible to eliminate the force transducer. The system uses the acceleration of the test tire during the spinup after being locked as the indication of pavement friction.
