ABSTRACT

This paper discusses the hypotheses, assumptions and methodology of a bridge consumption analysis that allows an asset manager to estimate bridge consumption costs per mile for road functional classes and geographical locations in the State of Texas. The methodology uses road and bridge inventory data and allows the user to address the differences in bridge densities per mile observed in different geographic regions such as Texas counties, and urban and rural areas. The analysis results are summarized in a series of spreadsheet, one for each of the 24 truck configurations of interest, so that the asset manager can estimate bridge consumption in cost/mile for any given route and geographical area. These results are being used to calculate permit prices for non-standard truck configurations such as large ocean container haulers.
