Abstract
The main goal of this work is to determine the economic feasibility of Fiber Reinforced Polymer (FRP) as the primary material for construction of short span bridge decks. The analysis is based on a comparison of the lifecycle costs for a cast-in-place steel reinforced concrete bridge and FRP bridge deck over a 60-year time horizon; both have dimensions of 8.0 m (26.3 ft) long by 8.3 m (27.2 ft) wide. The total cost estimate using the FRP material ranges from $82 to $182 per square foot ($882â$1958 per sq meter) with a range average of $132 per square foot ($1,420 per sq meter). It is also shown that the breakeven construction cost of the FRP deck is $113 per square foot ($1216 per sq meter) for a discount rate of 2%. The main factors affecting the analysis are costs of material, traffic delays, and discount rate.
