- Abstract
Low speed skid resistance measurement is of great significance to analyse the actual causes of insufficient friction of pavement, and to formulate appropriate maintaining measures. At present, the British Pendulum Tester (BPT) and Dynamic Friction Tester (DFT) are commonly used to measure the low-speed skid resistance of pavement. However, previous studies have shown that there are operational limitations in the use of BPT and DFT. A new low speed friction tester (WFT) developed by Chang'an University was introduced in this paper. The stability, accuracy and efficiency of BPT, DFT and WFT were compared through laboratory tests and field tests. The influence of test speed on WFT test results in the range of normal walking speed was evaluated. Results show that the stability of WFT test was better than that of BPT and DFT. BPT test results were unreliable and DFT was unsuitable for coarse surfaces or groove surfaces of pavement. WFT is time efficient in testing time, especially in field tests. The study also shows that the test speed had little effect on the WFC at the statistical significance level of 95%. Therefore, WFT can be used as a practical alternative to BPT and DFT, for testing the low-speed friction of pavement in laboratory and field
