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 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 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:

6 MEASURE Terminology

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

8 Preventive Maintenance is a component of Pavement Preservation

9 Pavement Preservation Programs encompass: Corrective & Routine Maintenance Preventive Maintenance Minor Rehabilitation 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 Pavement Management Systems Long-Term Network Planning Optimization Cost-Effective Decision Making Sustainable Financing

11 Rehabilitation Minor Rehab Extends Life TIMER TIMER Adding More Time

12 Rehabilitation Major Rehab Originates Life TIMER TIMER Initiating Time

13 Preventive Maintenance is NOT about Maintenance as Usual

14 Rehabilitation Trigger Original Pavement The Pavement Preservation Concept Very Good Fair Poor 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) 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 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 Network Condition Planning

22 Pavement Management Decision Triangle Pavement Management Decision Triangle Preventive Maintenance Rehabilitation Reconstruction

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

24 Reconstruction Strategy (20, 25, & 30 Year Fixes) Reconstruction Strategy (20, 25, & 30 Year Fixes)

25 Combined Reconstruct and Rehab Strategy (10 to 30 Year Fixes)

28 MEASURE Commitment of Leadership

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

30 MEASURE Training

31 Training is needed for: 1. Department Personnel Maintenance Design Construction Materials Planners Contract Agencies 2. Contractors 1. Department Personnel Maintenance Design Construction Materials Planners Contract Agencies 2. Contractors

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

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

34 MEASURE Validation of Program

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

36 Georgia’s Results

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

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