THE RELATIONSHIP OF LOCKED WHEEL FRICTION TO THAT OF OTHER TEST MODES

This report describes a test program in which a modified single wheel skid tester was used to obtain data in locked wheel, yaw (cornering), and transietn slip modes for seven pavements. Correlation coefficients between the data for the various modes are reported. High correlation is found between Peak Brake Slip Number and Skid Number, Peak Side Force Coefficient and Skid Number, and Peak Side Force Coefficient and Peak Brake Slip No. The speed gradients of the same data are shown to be uncorrelated.
