DETERMINATION OF SKID RESISTANCE-SPEED BEHAVIOR AND SIDE FORCE COEFFICIENTS OF PAVEMENTS

Pavement friction characteristics including skid resistance-speed dependence, side force coefficients, and brake slip numbers are seen to be derivable from data obtained in the transient slip test. The transient slip test is described, and it is noted that any friction tester with force-measuring transducers can be used for these measurements. The brake slip numbers are shown to be independent of the rate of wheel lockup, which leads to the observation that brake slip numbers obtained during a transient slip test are equivalent to locked-wheel skid numbers at the same sliding speed. Side force coefficients can be computed from transient slip data with the help of a model. The data and conclusions apply to the standard skid-test tire operating under fixed test conditions and normal load, water film thickness, and inflation pressure. /Author/
