CASE STUDIES-USING EAROMAR

Decisions among competing pavement investment and maintenance strategies must be based upon economic analyses considering both the costs and impacts of each strategy. Such analyses are sensitive to several local factors, including initial pavement design and construction, traffic loads, climate, maintenance and rehabilitation policy, maintenance technology, and unit costs. Of particular importance here are maintenance and rehabilitation actions, whose effects on pavement performance have not been studied extensively or quantified in the past. To enable highway administrators and engineers to account better for the interactions among the several factors above in influenceing strategy selection, we have redesigned and recoded FHWA's EAROMAR system to produce a second version of this product. EAROMAR simulates freeway operational and structural performances to predict life-cycle roadway costs. These costs include highway agency expenditures for roadway reconstruction, rehabilitation and maintenance, and user costs of vehicle operation, travel time (including congestion) and accidents. This report illustrates EAROMAR's use through application in a case study and through a set of sensitivity runs. The case study deals with pavement reconstruction vs. rehabilitation alternatives on Rt. 128 in Massachusetts, a 6-to-8-lane freeway handling in excess of 100,000 vehicles per day. The types and sources of data required, the results predicted, and analyses of these results to develop specific conclusions are discussed. (Author)
