The coefficient of friction measuring devices must ensure the correctness of the results, since the assessment
of the anti-skid properties of the pavement surfaces affect the pilot’s decisions upon the landing maneuver.
Accepted repeatability of measurements at the level of ±0.03 and reproducibility at the level of ±0.07 is not
a sufficient condition for acceptance of the measurement system. The paper presents an approach to evaluating
systems that measure friction coefficient of pavement of functional elements of airports. Measurements
for specific conditions were made in 10 series, on cement and asphalt concrete surfaces, at 65 km·h–1 and
95 km·h–1, under dry and wet conditions. The assumption of normality of distributions was verified based on
the Shapiro-Wilk test by analyzing W statistics. It has been observed that the coefficient of friction measured
using the friction testers attained different values for the same test conditions. Considering the reference
tester, straight regression lines were plotted to determine the corrected coefficient of friction.
