• Description:
  The Colorado Department of Transportation (CDOT) is faced with a conflicting challenge: (1) provide winter driving safety, which is enhanced by applying effective deicers such as magnesium chloride and (2) provide a durable, cost-effective transportation system, which is adversely affected by these same deicers. While nationwide research is underway on the effects of magnesium chloride, CDOT must continue deicer application, and simultaneously design, build, and maintain durable structures before this research is complete. This study was initiated to develop performance-based testing procedures to aid CDOT's concrete selection and protection process. The study was also to evaluate commercially available products developed to resist deicer deterioration in parking garages, which may extend the service life of concrete bridge decks, and lower their life-cycle costs. Two parameters were tested that are significant to bridge deck and steel deterioration: chloride intrusion (that causes corrosion in the reinforcing steel), and loss of surface abrasion resistance (wear).
