Washington's 2015 high-friction road treatment on Snohomish ramps

Washington state transportation crews in 2015 bonded ultra-hard bauxite chips to a highway ramp in Snohomish County using polymer resin, a high-friction surface treatment designed to give vehicles better grip. The coating is intended to reduce crashes on curves and ramps, particularly in wet weather when standard pavement loses traction.
