摘要：	Understanding the relationships between road surface properties and high speed friction is key to managing the risk of loss of vehicle control. It is understood that, in wet conditions, texture depth plays an important part in the generation of locked-wheel high speed friction. For the majority of road surfacing materials low levels of texture depth are likely to correlate with low levels of friction. However, this is not the case for all surfaces as previous works have shown there are some surfaces that provide low levels of texture depth and high levels of friction. The work documented in this report explores the relationship between high speed friction and road surface properties with a view to identifying the mechanisms by which materials can provide low levels of texture depth yet high levels of locked-wheel high speed friction.
