The following plot, Figure 12, graphically presents the application <strong>of</strong> pavement rehabs for asphalt<br />

streets by PCI and Distress Deducts.<br />

3.2 FIX ALL AND ANNUAL ESTIMATES<br />

Figure 12 – ACP Rehabs by PCI and LAD<br />

Three different approaches may be taken to identify the amount <strong>of</strong> funds the <strong>City</strong> needs to set aside each<br />

year to maintain the roadway network at its current condition. All three are completed external to the<br />

pavement management system and are simply used to validate the final results.<br />

A ballpark value for the annual street maintenance budget may be quickly determined by taking the total<br />

value <strong>of</strong> <strong>Bartlesville</strong>’s roadway network, estimated at $304.8M, and dividing that by the ultimate life a<br />

roadway – assumed to be 100 years. By this method, the annual budget is estimated at $3.05M.<br />

Network Valuation ($M): 304.8<br />

Ultimate Roadway Depreciation Life (yrs): 100<br />

Annual Budget Based on Depricatied ($M/yr): 3.05<br />

A second method to validate the annual budget is to identify the average network PCI and associated<br />

rehabilitation requirement, and then estimate the number <strong>of</strong> miles required to be rehabilitated each year<br />

based on a typical life cycle for that rehabilitation activity. For <strong>Bartlesville</strong>, the average PCI is 65, which<br />

places the <strong>City</strong> midway in the thin overlay – surface treatment range. At an average cost <strong>of</strong> $170,000/mi<br />
