Assessment of operational characteristics of continuous friction measuring equipment (CFME)
There are many devices used around the world to measure friction. The majority of Departments of Transportation in the USA currently use locked-wheel trailers for friction measurements. The use of the fixed slip devices has gained popularity in other countries, especially in Europe, and they are starting to be used in the USA. These systems measure the friction under the condition similar to those produced by anti-lock braking system. This paper evaluates the effect of grade, water film thickness and speed on friction measurements of the continuous friction measuring equipment. The data used in this study were collected at the Virginia Smart Road using the GripTester. The experiment showed that grade affects the GripTester measurements suggesting that measuring with GripTester would be more accurate on flat surfaces. It also confirmed previous results that measurements were shown to be sensitive to water film thickness and testing speed.
