1. Introduction
With the continuous deterioration of the nation's infrastructure, it was found that over half of the nation's 607,000 bridges were built before 1940 [1]. These bridges have reached the end of their useful service lives. In a study recently conducted by Ellis [2] for the Federal Highway Administration (FHWA), the estimated annual direct cost of repairing corrosion on highway bridges was between $6.43 and $10.15 billion. This estimate includes the $1.07 to $2.93 billion needed each year to maintain the concrete bridge decks. In an effort to address these sobering statistics, transportation agencies have been trying to identify new, cost-effective, and reliable construction materials that can be used to not only fabricate but also rehabilitate bridge decks. Advanced composites made of fibers embedded in a polymeric resin, also known as fiber-reinforced polymer (FRP) materials, have received considerable attention as a strong candidate to replace deteriorating concrete and steel structures. These composites, commonly used for civil engineering applications, are reinforced with an inexpensive fiberglass. The advantages of FRP composites have been widely recognized and include their low weight, ease of installation (reducing traffic delay), resistance to both environmental and chemical attacks, and resistance to fatigue loads. Extensive durability studies have been conducted on FRP composites for aerospace and marine applications. Autoclave-based fabrication was used to manufacture each of these applications under strict specifications. Cheaper manufacturing processes have been used in the civil market (e.g., wet layup, vacuum assisted resin transfer molding [VARTM], and pultrusion), resulting in lower temperature cure epoxies. The FRP composites used in the field for rehabilitation purposes are cured under ambient temperatures. Thus, these composites are more vulnerable to moisture damage and plasticization than those used for
