City of Austin Performance Report 2014-15
Total Number of Lane Miles of Street Preventive Maintenance Completed
Preventive maintenance (PM) of existing pavements extends the life of the surfaces and reduces the amount of capital investment required on City streets each year. Asphalt overlaying, thin surface treatments, and crack sealing existing surfaces are the primary components of the Department’s PM program.
This measure is calculated by summing the total number of lane miles that receive a preventive maintenance method in order to extend the useful life of the street inventory.
FY 2014-15 Results
With 606.7 lane miles of preventive maintenance completed in FY 2014-15, performance fell below the goal of 772 lane miles by 21.4%.
Assessment of Results
This indicator is the total lane miles of various street preventive maintenance treatments, specifically crack seals, thin surface treatments, and asphalt overlays. In FY 2014-15, crack seal, thin surface, and overlay treatments covered 123, 368, and 116 lane miles, respectively. Although work performed by the “in-house” workforce met their internal targets, contracted work did not materialize due to lack of funds. Funds originally slated for contracts were repurposed to meet an unanticipated budget shortfall. As a result, 60 lane miles of asphalt overlays and 140 lane miles of thin surface treatments anticipated for FY 2014-15 were not completed by contract.
Public Works (PWD) will use an automated work order and asset management system in FY 2015-16 to continually improve its ability to schedule and monitor work, increasing the reliability of data collected. The use of the work order management system is critical as PWD implements the use of various street preventive maintenance treatments and types of technologies that will increase the need for reporting progress requirements. Also, PWD started development of a new pavement management system that will allow greater efficiencies when developing a Service Plan of street preventative maintenance activities. PWD plans to continue to supplement in-house efforts with contracted work for preventive maintenance treatments as a tool for maintaining 80-85% of lane miles in satisfactory or better condition.
