SHRP LIFE-CYCLE COST METHODOLOGY FOR TREATMENT OF CONCRETE BRIDGE COMPONENTS

As part of the Strategic Highway Research Program (SHRP) implementation, FHWA has developed and is conducting a workshop nationwide entitled "Methodology for Design and Treatment of Conc Bridge Components Subject to Corrosion of Reinforcing Steel." An important component of this workshop is a life-cycle cost analysi methodology used to select the most cost-effective strategy for treatment of concrete at the project level. Two versions of the methodology have been developed: a handbook with worksheets and nomograms for manual calculations and a computer program titled "CORRODE" software for automated calculations. Through the SHRP showcase, bridge engineers and managers in several states have be introduced to the methodology for determining which treatment - s as concrete overlay, cathodic protection, sealer or membrane - to on reinforced concrete bridges to minimize life-cycle costs. Usin the results of tests specified, the methodology assesses the condition of the concrete. That information is then used to systematically predict how the condition can be expected to chang time and when the maximum tolerable condition is reached. Subsequently, several treatment alternatives are examined, and it predicted how the concrete component might perform in the future after each treatment. For each treatment, a life-cycle cost is computed. The life-cycle cost analysis considers both agency cost bridge user cost. The results of the life-cycle cost analyses are compared to determine which treatment alternative has the lowest life-cycle cost and when the treatment should be applied.
