This report describes an experimental program that investigated the braking and hydroplanning performance of an aircraft tire on asphaltic concrete surfaces having various treatments. The tests were conducted on a dynamic track in the speed range of 70 to 150 knots, and under other operating conditions whose magnitudes represented values widely used by airlines or aircraft. The results show that the type of surface treatment has a significant influence on the braking performance of an aircraft tire on puddled runways, grooves at closure spacings provide higher friction levels. When the runways are wet or flooded the braking capability on all surfaces is either very high or very low, respectively. The braking performance on the reflex-percussive grooves, the porous friction overlay, and the saw-cut grooves spaced at 3 inches is comparable.
