“…The disc rotates horizontally at a linear speed of about 20 to 80 km/hr under a constant load. The rubber pads can touch the pavement surface at different speeds so the DFT can measure the skid resistance at various speeds [85]. In a study, Saito et al [85] showed that the coefficient of friction of the DFT and the British Pendulum Number (BPN) have a high correlation at each point for each measuring speed [85].…”

“…This device can be used to measure pavement friction characteristics in the laboratory or at low speeds in the field. The BPT is easy to handle, can be used in the laboratory and in the field, but its result is only a measure of frictional property at a low speed [85].…”

“…The rubber pads can touch the pavement surface at different speeds so the DFT can measure the skid resistance at various speeds [85]. In a study, Saito et al [85] showed that the coefficient of friction of the DFT and the British Pendulum Number (BPN) have a high correlation at each point for each measuring speed [85]. Both British pendulum and DFT device procedures are based on determining the loss in kinetic energy of a sliding pendulum or rotating disc when they are in contact with the pavement surface.…”

“…The ribbed tire is insensitive to the thickness of the pavement surface water film and is insensitive to the pavement macro-texture, but the smooth tire is sensitive to the macro-texture of the pavement surface [4] [84]. Saito et al [85] enumerated some of disadvantages associated with locked wheel testers:…”

“…In this test the test wheel must maintain a constant angle (yaw angle) to the direction of motion [1]. The side-force method test wheel moves at an angle to the direction of vehicle motion because the critical situation for skid resistance occurs in cornering [85].…”

Driving safety is of significance in the automobile industry and transportation systems. Pavement skid resistance has long been recognized as the most important parameter in reducing traffic accidents especially in wet conditions. The knowledge of the friction coefficient and skid resistance is very valuable information for safety enhancement of roads. Thus, it is important to find proper methods for measuring skid resistance and frictional properties of the pavement surface. There is a wide range of measurement methods and devices for measuring skid resistance. This paper presents a review on the research studies that have been done on characterization of the frictional properties of the pavement surface and discussed methods used for measurement and evaluation of texture characteristics and the strengths and weaknesses of these methods. Finally, some ideas have been suggested to develop new methods for better and proper measurement of skid resistance.
