Title:

Evaluation of Products That Protect Concrete and Reinforcing Steel of Bridge Decks from Winter Maintenance Products

Abstract:

This study was initiated to develop performance-based testing procedures to aid the Colorado DOT'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). The results of this study indicate that surface abrasion testing can readily be implemented on both laboratory samples and on field projects, to assess the resistance of various concrete mixtures and coatings to vehicular traffic wear. The rapid chloride permeability test proved valuable to assess the resistance to chloride penetration of these same concrete mixtures and coatings.
