MnDOT’s TAMP Pavement Life Cycle Costs

 Identify Better Management Strategies  Quantify Future Maintenance  Determine Appropriate Treatments

Life-Cycle Costs Iceberg Initial Capital Expenditures Maintenance Costs Future Capital Costs Operational costs are not part of LCC, but are part of overall management $ Background image:

 Established Pavement Technical Work Group  Materials (i.e. pavement office) & District maintenance staff  Subject matter experts provided guidance on typical inputs and assumptions

 Analysis Period: 70 years  Discount Rate: 2.2%  Salvage Value Included  Costs Collected/Analyzed by $/Lane-Mile  Rigid pavements: 11%, Flexible pavements:89%  Only Agency Costs Considered  Annual Inspection Cost  $37 per roadway-mile

 Routine & Reactive Maintenance  MnDOT Metro spent $1.4 Million in 2012  Maintenance investment by condition (G/F/P) could not be determined  Maintenance performed 482 ln-mi of pavements: 295 in Good, 161 in Fair and 26 in Poor  Weighting factors applied to maintenance costs: Good-0.8, Fair-1.2, Poor-1.8  Equates to Good-$2340/ln-mi, Fair-$3480/ln- mi, Poor-$5229/ln-mi

 Typical, Desired, Worst First Strategies  Identify minor and major rehab surface treatments for asphalt and concrete Deterioration Models for Various LCCA Scenarios

MnDOT’s Post-TAMP Pavement Asset Management Initiative

 “Understand Life Cycle Costs of Major Assets” – Maintenance costs (TAMP)  Phase 1: Determine how much “labor, equipment, material (LEM)” was spent at certain asset conditions?  Pavement  Entering LEM in RCA; assigning reference points for certain (maint.) source codes  RCA RECORD is being divided into segments; matched to condition data from pavement Van (M-records) THREE M-RECORDS Roadway Segment RCA RECORD (TOTAL LEM) Reference Points LEM1 LEM2 LEM3

18 Pavement Van Condition Data LEM From Work Orders

19 Condition of Road Improves  Focus on RED LINE: As Condition Improves, Maintenance spends less money/mile
