Abstract
AbstractThis study examines the effect of aggressive freeze-thaw (FT) cyclic exposure on strength and integrity of bridge decks built using glass fiber-reinforced polymer (GFRP) stay-in-place (SIP) structural forms that completely replace the bottom rebar layers. The concern has been whether entrapped moisture may cause frost-jacking of the form, negatively impacting deck integrity. Eleven scaled deck specimens were built, each using two flat GFRP plates with T-shape ribs running normal to girders. Both plates spanned the gap between girders and were spliced by overlapping, directly under the load. The study simulated the following surface treatments of the form: no treatment at all, adhesive bond to freshly cast concrete, and coarse aggregates bonded to the forms. Also, unbonded and bonded lap splices of the forms were tested. The decks were subjected to three cracking load cycles before being saturated and subjected to up to 300 FT cycles at +5 to −18°C core temperatures. Freezing was in air while thawi...
