• Federal FHWA Requirements for NPMs vs. CDOT Drivability Life for PD-14

• Pavement Condition Based on National Performance Measures:

• Interstates and Non-Interstate NHS for the State of Colorado and the Denver Regional Council of Governments Region

• Discussion of NPM Pavement Condition Target Adjustment

• Adopted by Transportation Commission in September 2020

• MPO Role

December 2020 NPM Pavement Condition & Target Adjustment

National Performance MeasuresGeneral Information

• The Fixing America’s Surface Transportation Act (FAST Act) requires states to report pavement condition in Good/Fair/Poor format under 23 CFR 490. Metrics for safety, bridges, and system reliability are also required.

• Pavement performance metrics include the following:

• Performance of the Interstate System.

• Performance of the non-Interstate National Highway System (NHS), including off-system NHS.

• Under the FAST ACT, there is a minimum performance level for Interstate System pavement in poor condition—no more than 5 percent. If a state exceeds minimum condition, they lose flexibility of a portion of federal funds.

• Under CDOT’s Policy Directive 14, we currently report Drivability Life as the primary pavement asset management performance metric.

• CDOT uses PD-14 to assess long-term condition of transportation assets, including pavement. A revised Policy Directive 14.0 was adopted by the Transportation Commission on November 19, 2020.

NPM Pavement Condition & Target Adjustment

National Performance MeasuresAssessing Pavement Condition

• Measured on condition of three distresses: • International Roughness Index• Cracking Percentage• Rutting (Asphalt)• Faulting (Concrete)


National Performance Measures

vs. Drivability Life

Drivability Life

• Pavement distresses• IRI – International Roughness Index

• Rutting

• Cracking

• Faulting

• To have a low DL segment, one distress must fall below an acceptable threshold

National Performance Measures

• Pavement distresses• IRI – International Roughness Index

• Rutting

• Cracking

• Faulting

• To have a poor segment, two distresses must fall below an acceptable threshold

5

• The FAST Act mandates a pavement performance measure that uses a different methodology for pavement

condition; state DOTs must report pavement condition in terms of Good, Fair, and Poor condition. This

methodology for assessing pavement condition has accurate data only back to 2018.

• Under CDOT Policy Directive 14, drivability life is used as the primary pavement asset management performance

metric for investment decisions. This metric has been in use for pavement condition assessment since 2012.

of 2020. This target was also adjusted in the October 2020 Mid Performance Period Progress Report submitted

to FHWA.
