Mathematical Model of Skid Resistance as a Function of Speed
Skid resistance has been modeled as an exponential function of speed involving two parameters, zero-speed intercept and percent normalized gradient are presented, and an alternative parameter called a "speed constant", which is free of those inconsistencies, is proposed. Two methods for identifying the model parameters are evaluated using test data collected on road sections in Pennsylvan…
Limitations of Using Skid Number in Accident Analysis and Pavement Management
Trr No. 1311 Pavement Design, Management And Performance, pp. 43-50 Pavement frictional characteristics are commonly determined by conducting skid tests in accordance with ASTM Standard E274. The results of these tests (skid number/SN) are used in ranking roads to establish construction priorities and to estimate tire-pavement friction in accident analysis. The role of SN in these two applicat…
