The static contact patch of some friction measuring devices
2014
The tyre/asphalt interface influences a wide range of pavement properties. Compared to other areas of highway research there has been relatively little work done into better understanding this interface given its importance. One of the main problems has been with acquiring data relating to what is happening at this interface. This paper looks at the static contact patch or interface of some measuring devices typically used to measure highway and airfield wet friction. The investigation used a high resolution XSensor pressure pad to measure pressure distribution within the contact patch.
