Abstract
In Taiwan, many manhole covers, which cause skid risk to two-wheel vehicles under wet weather condition, are installed on the road. To reveal how the manhole covers affect the road safety, this study carried out a survey that investigated the skidresistance of 99 manhole covers with 3 different instruments, the GripTester, the British Pendulum Tester, and the Dynamic Friction Tester. The result shows that most of the covers currently on the road do not have good enough skid resistance, while the new-casting covers all performed good skid resistance in the survey. Accordingly, the skid resistance of roads should be rectified by replacing overly old covers with new ones. © Chinese Society of Pavement Engineering.
