Maintaining a pavement’s friction is important for safe driving. Traditional high-friction surface treatments consist of applying a polymer resin to the existing road surface and topping it with high-quality aggregates to help drivers maintain control at existing or potentially high-crash areas. However, this type of treatment can be relatively expensive and not well-suited to all locations.
To identify alternative solutions, the Missouri Department of Transportation (MoDOT) conducted a research study to evaluate the costs and performance of surface treatments made with asphalt-based binders. The results will help MoDOT maintenance crews select cost-effective treatments for the state’s roads.
