Pavement asset sustainability ratio targets established.

This bill requires Minnesota's Department of Transportation to track and report on pavement maintenance quality using a specific metric called the Asset Sustainability Ratio (ASR). The ASR is calculated by dividing "total mile years added" by "total system mileage," with targets set at 0.65 by 2027, 0.75 by 2029, and 0.85 by 2031 and beyond. The department must include these annual ASR results in its official transportation performance report. This directly affects the Minnesota Department of Transportation, mandating measurable goals for pavement maintenance rather than changing road construction methods.
