of data is critical to bridge life cycle asset management. When building a new bridge or bridges had simple, wood frame operator houses and were operated manually. Table 1 lists the below the bridge deck, the need for through-trusses was eliminated. These efforts resulted in
Applying LCCA to Bridges by Adel Al-Wazeer, Bobby Harris, and Christopher Nutakor. A few States, however, have developed models to predict the life cycle of the bridge deck, for example, by using a repair matrix based on the condition rating and the actions taken.
Types of Bridge Decks By Will Wood bridge decks are almost uniformly constructed with metal support systems to both reinforce the strength of the material and provide insurance against possible weakening and failure of wood in the face of extreme heat and moisture. Heat can cause wood to buckle and morph while constant rain or snow weakens

Fast installation with less disruption to traffic, and reduced long-term maintenance two compelling reasons for the selection of a composite bridge deck
Fiber-reinforced-polymer FRP composites are currently being developed and used in bridge decks. This report examines the life-cycle cost-effectiveness of three FRP bridge decks, using a life-cycle cost method specifically tailored for comparing new materials with conventional ones. The method
Over the last few years there has been a renewed interest on the use of timber-concrete composite TCC structures in bridge decks, possibly because of their cost competitiveness and environmental friendliness. Accordingly, this paper investigates the sustainability of TCC bridge decks under a
Lumber Life Cycle: Wood vs. Composite Decking Decks. Posted on: April 22, 2011. Green Vocab but the lumber industry wants to simplify that by suggesting a single best option for deck-building: wood. A recently published life-cycle assessment LCA comparing pressure-treated wood PTW

The most commonly constructed deck element is the concrete deck slab. This structural slab is designed to be between 7 and 9 thick and is reinforced with two layers of steel reinforcing bars. Many times these bars are coated with epoxy for corrosion protection depending on the bridge location and environment.
