Description: What's the Cost to Society?, finds that automobile crashes cost U.S. motorists more than $164 billion per year, or about $5 trillion over the past three decades, taking into account property damage, lost earnings, medical costs, emergency services, legal costs, and travel delays. According to the FHWA report Surface Finishing of Portland Cement Concrete Pavements (FHWA-SA-96-068), surface treatments using epoxy resin and calcined bauxite can improve the friction of existing portland cement concrete surfaces on roadways with high numbers of wet-weather crashes. Road crew workers can apply high-friction surfacing treatments on top of most road surfaces, including asphalt, concrete, steel, and wood.\n "It is evident based on anecdotal information from the site that there is a marked improvement in skid resistance over the previous surface in all weather conditions," says Tim Ujvari, chief of the commission's regional maintenance department that carried out the project.
