Pavement skid resistance, which depends on slip speed, is an important factor impacting traffic safety. To deeply understand the relationship of asphalt pavement skid resistance to slip speed, field tests are conducted using Dynamic Friction Tester (DFT) at 33 test sites of 11 sections with various highway grades and surface types. Friction coefficients corresponding to various slip speeds (0 km/h through 80km/h by 0.1 km/h) are obtained for each test site. Evaluations show that the Penn State Model is not suitable for characterizing the curve of slip speed-friction coefficient measured by DFT. Then, a new model with 3 parameters is developed. Regression analysis of the 33 DFT measurements shows that the new model can accurately describe the relationship of asphalt pavement skid resistance to slip speed measured by DFT. It has the potential to improve skid resistance evaluation of asphalt pavement.
