How to determine PCI score?

  • The type, extent and severity of pavement surface distresses (typically cracks and rutting)
  • The smoothness and ride comfort of the road

  • Poor: (PCI 41) Good: (PCI 62) Excellent (PCI 92)

    Pavement Life Cycle

    Importance of preserving pavements

    • ~ Testimony of State's case ~
    • California, Georgia, Michigan, New York, Texas, and Georgia successfully implemented a pavement-preservation program.
    • Rehabilitation and reconstruction projects cost about 14 times as much as preventive maintenance projects per lane-mile.
    • Michigan has enjoyed a cost savings of more than $700 million since 1992.
    • Preventive maintenance treatments can extend its service life by 5 to 7 years.

    Major Type of Pavement Distress

    Alligator Crack
    Hover over me!
    Possible Cause:
    Most often the result of traffic or load related
    Alligator (Fatigue) Cracking

    - A series of interconnected cracks look like alligator skin

    Block Crack
    Hover over me!
    Possible Cause:
    - By shrinkage of the asphalt concrete and daily temperature cycling
    - Not load related
    Block Cracking

    - A pattern of cracks looks like rectangular blocks
    - Occuring over a large portion of the area

    Longitudinal/Transverse Crack
    Hover over me!
    Possible Cause:
    - By shrinkage of the asphalt concrete and daily temperature cycling
    - Not load related
    Longitudinal/Transverse Crack

    Longitudinal: Parallel to the centerline
    Transverse: Perpendicular to the pavement centerline

    Pothole
    Hover over me!
    Possible Causes:
    Eroding the material under the pavement by water seeping into cracks
    Pothole

    - Bowl-shaped holes on the pavement surface

    Rutting Depression
    Hover over me!
    Possible Causes:
    - Failure in the lower pavement layers
    - traffic load related
    Rutting / Depression

    - A linear depression in the wheel path

    Pothole
    Hover over me!
    Possible Causes:
    - Often a combination of many factors including weather, inadequate installation,and heavy loading
    Weathering/Raveling

    - Wearing away of the pavement surface or top coat

    Pavement Treatment

    Condition PCI General Treatments Stragegy Examples
    Excellent 90- 100 Do Nothing/Corrective Maintenance
    Very Good 70 - 89 Preventative Maintenance Chip Seals, Cape Seals, Crack Seals, Fog Seals, Slurry Seals, Microsurfacing
    Good 50 - 69
    Poor 0 - 49 Rehabilitation/Reconstruction Mill & Fill, Overlay
    Select treatment type

    Our Mission
    Maintain systemwide PCI at or above 82 by applying a variety of cost-effective maintenance treatments. By applying the right treatment at the right time, the City can lower costs by reducing the need for future roadway rehabilitation.
