Abstract

This paper describes a comparison performed between two experimental procedures (with the Grip Tester and the Continuous Friction Measurement Equipment) of the fixed-slip method for longitudinal continuous friction measurement in airport pavements. The measurement framework is described, namely, the experimental testing and the related conformity assessment procedure supported by different friction thresholds. The experimental results of the comparison are presented (raw data, differences between friction estimates and corresponding experimental probability distributions) and its impact on the conformity assessment result is discussed. Conclusions are drawn based on the obtained difference dispersion, instrumental measurement uncertainties and expected difference between the two experimental procedures.
