Abstract (Limit: 250 words) <br />This report documents the development of an analysis procedure and an associated computation tool to <br />estimate the impact of heavy vehicles on local agency pavements. The heavy vehicles of interest are those <br />which were not anticipated at the time the pavement structure was designed, but which cause additional <br />damage and thus create the need for rehabilitation or reconstruction sooner than expected. These <br />unexpected heavy vehicles could be generated by new industrial facilities, mining activities, changes in <br />urban waste collection patterns, temporary heavy construction in a limited geographical area, or for other <br />reasons. The tool described in this report implements the procedure, and provides users with the ability to <br />analyze a single roadway segment (for detailed impacts estimates) or an agency's entire network (for <br />summary statistics over the system). The tool provides estimates of the percent of originally intended life <br />that may be used by the unanticipated vehicles, the additional pavement structure that would have been <br />required at construction to accommodate the additional vehicles, and the additional damage that they <br />cause. The tool is contained in a macro -enabled Microsoft Excel spreadsheet and does not need additional <br />files or external functionality to conduct an analysis. <br />17.
