  1. Using Measure to Create a Capital Pavement Preservation Program

  2. EVOLVING DEMANDS • Highway Usage Increased 29% in the 1990’s • Truck Traffic Increased 40% in the 1990’s • Truck Traffic Will Increase 3% per year in next 20 years

  3. CONSEQUENCES • Operating Revenues Can’t Keep Pace with Needs • Highway Agencies Face Increasing Demands with Decreasing Resources

  4. The Solution: Pavement Preservation Improves the Performance of the Network while Spending Less Program Dollars

  5. Reference: Strategic Planning for Pavement Preventive Maintenance

  6. MEASURE • Terminology

  7. Is there terminology confusion? • Design Life • Service Life • Life Extension • Routine Maintenance • Preventive Maintenance • Minor Rehabilitation

  8. Preventive Maintenanceis a component ofPavement Preservation

  9. Pavement Preservation Programs encompass: • Corrective & Routine Maintenance • Preventive Maintenance • Minor Rehabilitation

  10. Pavement Preservation components include: • Pavement Management Systems • Long-Term Network Planning • Optimization • Cost-Effective Decision Making • Sustainable Financing

  11. TIMER TIMER 0 0 45 15 45 15 30 30 Rehabilitation Extends Life Minor Rehab Adding More Time

  12. TIMER TIMER 0 0 45 15 45 15 30 30 Rehabilitation Major Rehab Originates Life Initiating Time

  13. Preventive Maintenance is NOT aboutMaintenance as Usual

  14. The Pavement Preservation Concept Original Pavement Very Good Good Fair Poor Rehabilitation Trigger Very Poor Time (Years)

  15. MEASURE • Business Processes

  16. Preventive Maintenance Projects Need a Different Business Process • Faster Scoping & Designs (Lower PE costs) • Blanket Clearances • Expedited Project Reviews • Shorter Construction Duration (Lower CE costs)

  17. Preventive Maintenance Projects Need a Different Business Process • Uniform Specifications • Standard Traffic Control • Abbreviated Advertisements

  18. Chip Seal

  19. Crack Sealing

  20. MEASURE • Integration of Preventive Maintenance into the Pavement Management System

  21. Quality Data • Network Condition • Planning

  22. Preventive Maintenance Pavement Management Decision Triangle Rehabilitation Reconstruction

  23. “Mix of Fixes” Approach • Reconstruction • Rehabilitation • Preventive Maintenance

  27. PMS Thresholds

  28. MEASURE • Commitment of Leadership

  29. Indicators of Commitment: • Dedicated Budget • Long-Term Strategy • Assignment of a Champion • Support the Change

  30. MEASURE • Training

  31. Training is needed for: • Department Personnel • Maintenance • Design • Construction • Materials • Planners • Contract Agencies • Contractors

  32. Training Needs: • Terminology • Pavement Indicators for Preventive Maintenance • Treatment Characteristics • Work Zone Development • Inspection

  33. Training Needs: • Network Level Planning • Project Level Planning

  34. MEASURE • Validation of Program

  35. Life Extension PMS Data Point Very Good Good Fair Poor Very Poor Time (Years)

  37. Achieve “Life Extension“ Results Lower Rate of Deterioration Network Condition Improves Fixes are Cost Effective Validation of Success

  38. Increased User Satisfaction Improved System Safety Reduced Cost/Mile Expenditures Lower Life Cycle Cost Validation of Benefits

  39. The End
