When a nonrotating tire moves from a quasi-dry section to a flooded section of a pavement, a transition from a nonhydroplaning to a hydroplaning state may occur. During this transition, friction force drops from a higher level to a lower level. This transition phenomenon was investigated experimentally. The experimental program was conducted both in the laboratory on a moving-belt friction tester and on the highways at the Pennsylvania Transportation Institute Research Facility. Good agreement was found between the laboratory and the highway test results. The results showed that the transition time could last up to 65 ms under the limits of operating conditions employed in the test program. The operating conditions included the test speed, the water-film thickness, the tire-inflation pressure, the vertical load on the tire, and the microtexture of the pavement. (Author)
