Service life of concrete bridge decks is often cut short indirectly, due to deterioration mechanisms that exist at early ages of the concrete. Early age deterioration mechanisms such as early age cracking cause the reinforcing steel rebar to be exposed prematurely to the elements of the environment, which causes for lower service life of the bridge deck through corrosion of the reinforcing steel in the bridge deck. In harsh environments, such as the Midwestern United States, the premature exposure can cause devastating effects to service life. In order to prevent early deterioration, it is imperative to examine early age hardened properties of the concrete and fresh properties of the concrete in order to produce the best defect-free bridge deck available which will promote long service life. In order to examine early age hardened properties and fresh properties of concrete to be used for bridge decks on the Illinois Tollway, laboratory testing was performed by CTL Group and the University of Illinois at Urbana-Champaign. Through extensive laboratory testing, results indicate that many mitigation strategies are able to improve early age cracking in concrete for bridge decks.
