Innovative hybrid wearing surfaces for FRP bridge decks

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Corrosion of steel reinforcing bars in concrete bridge decks is considered the primary limit state in severe environments. Fiber reinforced polymer (FRP) composite bridge decks are durable alternative to steel reinforced concrete bridge decks. However, conventional wearing surface materials used on concrete bridge decks do not adhere well to GFRP bridge decks. This paper presents the results of an experimental research that focuses on durability of wearing surfaces used on FRP bridge decks. The wearing surfaces investigated under this program were epoxy polymer concrete, polymer modified concrete, polymer modified asphalt, and asphalt. Several thermal compatibility tests were conducted. The results of this research suggest that polymer concrete adheres best to GFRP decks, while polymer modified concrete exhibits the best wear resistance. Three wearing systems were developed and presented.
