Abstract

Accurate modeling of tire/pavement friction phenomena is of utmost importance in many applications such as vehicle braking control and frictional evaluation of pavements. LuGre tire friction model is a model which is used for this purpose by estimating its parameters using measured pavement friction data. In this investigation, LuGre model parameters were estimated using field data collected by a standard pavement friction measuring device (Locked Wheel Skid Trailer-ASTM E 274) at a group of pavements with different surface friction properties. Adequacy of the model to predict measured friction data from the device was statistically evaluated and the accuracy of estimated model parameters was determined. The results show the potential of this model to facilitate frictional evaluation of pavements using dynamic friction measuring equipment.
