1. The mix of the road material contributes to dry road surface friction . 2. Surface friction and roadway safety are important considerations as well for pavement decisions.3. The spinning effect, along with surface friction , usually will produce a forward momentum. 4. Surface friction also causes winds to blow more inward into low pressure areas.5. Typically the lubricant-to-surface friction is much less than surface-to-surface friction in a system without any lubrication. 6. Typically the lubricant-to-surface friction is much less than surface-to-surface friction in a system without any lubrication. 7. Surface friction testers are used at airports and on major roadways before ice formation or after snow removal.8. Plasticity surface friction is also very low in comparison to the plastic deformation energy and can be neglected. 9. This layer, where surface friction slows the wind and changes the wind direction, is known as the planetary boundary layer. 10. In the absence of surface friction , contact stresses are normal ( i . e . perpendicular ) to the contact surface.
