Strategic Measure_Preventive Maintenance

This measure tracks the percentage of lane miles managed by the City of Austin that had preventive maintenance completed. Preventive maintenance 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 what constitutes the City's Preventive Maintenance program.

This dataset supports the measure M.E.3 within the Mobility outcome under the Strategic Direction 2023 initiative.

Data Source: Pavement Management Information System, Street & Bridge Operations

Calculation:
Total number of lane miles of street preventative maintenance completed* / Total number of lane miles managed

*Total number of lane miles of street preventative maintenance completed = Lane miles of overlay completed + lane miles of preventative maintenance crack seal completed + lane miles of preventative maintenance thin surface treatments completed.

Measure Time Period: Quarterly (Fiscal Year)

Automated: No

本指标追踪了奥斯汀市管理的道路里程中完成预防性维护的比例。现有路面的预防性维护可以延长其使用寿命，并减少每年对城市街道所需进行的资本投资。沥青铺面、薄层表面处理和裂缝密封是构成城市预防性维护计划的主要组成部分。该数据集支持战略方向2023计划下的移动性成果指标M.E.3。数据来源为道路与桥梁运营部门的路面管理信息系统。计算方法为：已完成的街道预防性维护总里程数除以管理的总里程数。其中，已完成的街道预防性维护总里程数等于铺面完成里程数加上预防性维护裂缝密封完成里程数加上预防性维护薄层表面处理完成里程数。测量时间周期为季度（财政年度）。自动化：否。上次描述更新日期：
