  • 1. SUSTAINABLE Quality Based Roads Program New York State County Highway Superintendents Association, Inc. Prepared For: 2012 Winter Highway & Bridge Professional Development Conference & Expo Prepared By : Robert Christman, P.E . - Technical Advisor Vanasse Hangen Brustlin, Inc .
  • 2. Sustainable Pavement Management Practices
    • Recycling
    • Warm Mix Asphalt
    • Porous Pavement
    • Pavement Preservation
    • Smooth Pavements
    • Longer Lasting Pavements
  • 3. Pavement Management Theory
    • Do the right thing at
    • the right time in the right place
      • Make timely maintenance repairs
      • Avoid more expensive, extensive repairs
    Avoid “Worst First”
  • 4.
    • Do the right thing : correct preservation maintenance application, HMA mix, rehabilitation alternative
    • At the right time : pavement management system analysis
    • In the right place : pavement management in consort with a master plan, combining pavement sections, plus the human factor
    And then… Do it the right WAY !
  • 5. Quality Based Roads Program (QBRP) 1. Pavement Management 2. Pavement Materials Evaluations 3. Construction Quality Assurance
  • 6. Quality Based Roads Program Elements
    • System level pavement management
      • Software-based or spreadsheet
    • Pavement materials evaluations and rehabilitation recommendations
      • Enforceable Hot Mix Asphalt construction specifications
    • QA testing/inspection at the production facility and QA testing/inspection on site of in-place materials
  • 7. 1. Pavement Management System Level Analysis
    • Professional, Objective, repeatable rating system
      • Develop Pavement Condition Index (PCI)
      • Track pavement performance
      • Prioritization
      • Budgets
    • Options
      • On the ground

  • 11. Pavement Preservation
    • Timely routine and preventive maintenance reduces the frequency of resurfacing
    • Energy consumption, aggregate consumption, and green house gas emissions are all reduced by the use of preventive maintenance treatments
  • 12. Pavement Preservation ISSA 45th Annual Convention - February 2007

  • 14. Pavement Management Goals
    • Invest now for large benefits later
      • pavements are one of your largest capital assets to protect
    • Perform timely maintenance now
    • Avoid expensive improvements later
    Do the right thing at the right time in the right place and do it the right way
  • 15. 2. Pavement Materials Evaluation
    • Preferred approach for pavements in need of capital repair
    • Provide owners/managers with the most cost effective and reliable rehabilitation alternatives for their pavements
  • 16. Typical Pavement Performance Curve Do Nothing Routine Maintenance Preventive Maintenance Structural Improvement Base Rehabilitation
  • 17. Project Level Evaluation
    • Obtain available project information
    • Establish existing condition of pavement
    • Determine the cause of distress
    • Identify feasible alternatives
    • Make recommendations
  • 18. Pavement Materials Evaluation
    • Obtain samples of subgrade/subbase, base and surface materials via test pits and cores
  • 19. Pavement Materials Evaluation
    • Field samples are tested and evaluated in AASHTO accredited materials testing laboratory by certified technicians
  • 20. Field Sampling and Testing For Pavements in Need of Capital Repair
    • Diagnose most probable causes of distress
    • Identify structural characteristics and layer material properties in existing pavement for sustainable selection incorporating:
      • Economics and Green Assessments
      • Recycling
      • Emphasis on rehabilitation, not reconstruction
    • Place materials engineer in the best possible position to make correct choice of pavement rehabilitation
  • 21. Causes of Pavement Failure Base related Age related Mix/Construction related
  • 22. Pavement Materials Evaluation
    • Base/subbase materials are often recommended for reuse or alternative pavement solutions are suggested, saving money.
  • 23. Pavement Materials Evaluation
    • Provides 5, 10, 20, 25+ year action plans for maintenance and rehabilitation of roadways and parking lots
    • If applicable, provide Life Cycle Cost Analysis (LCCA) of pavement alternatives to determine both initial and life-cycle construction and maintenance costs
    • If applicable, provide Life-Cycle
    • Sustainability Assessments
    • Cost to benefit ratio
  • 24. Proper Design
    • Paving Mixture Design
    • Pavement Structure Design
    • Sustainable Pavement Alternative Selection
  • 25. Pavement Evaluation Benefits
    • Less chance of premature failure
    • Better chance of achieving and exceeding intended design life
    • Better use of available funds and lower overall cost in the future
  • 26. Annual Project Development
    • Project scheduling
    • Future build coordination with utilities and site activities
    • Develop a strategic multi-year plan for maintenance and rehabilitation
    • Assign next year’s pavement evaluations

  • 27. Annual Project Development
    • Diversify your investments
    Preservation Maintenance Structural Improvement Base Rehab *Miles per dollar spent
  • 28. Annual Project Development
    • Communicate with the tax base
      • What, when and where projects are going to take place
    • Use media as a tool for education
      • Traditional and social media are a great way to keep the tax payer informed as to how you are saving them money

  • 29. Project Specifications
    • Develop specifications for quality enforcement , provisions for production quality factors and field placement quality specific to the owner’s needs
    • Include Superpave hot mix asphalt, mat and joint density with incentive/disincentive
  • 30. 3. Construction Quality Assurance “…doing it the right way”
    • Assure pavement preparation:
      • Cracks sealed
      • Localized deficient areas properly patched
      • Correct application of tack
  • 31. Construction Oversight
    • Sampling and testing at production facility during production/placement
    • Job site construction oversight
      • In-place density testing (QC)
      • Core sampling for payment factors (QA)
      • Smoothness testing of final surface via rolling straight edge or profilometer
  • 32. Longer Lasting Pavements
    • Planned Work
    • Properly Designed
    • Enforceable specifications
    • Construction oversight for specification compliance
  • 33. Why Do All This? 100 93 85 72-78 60-65 Preservation Maintenance 0 Pavement Materials Evaluations have saved 10-40% in rehabilitation capital costs Do Nothing Routine Maintenance Preventive Maintenance Structural Improvement Reconstruction
  • 34. NE Local Road Pavement Performance Study 2002 Quality Based Road Program $15/s.y. $2.75/s.y.
  • 35. The Payoff:
    • For every $1.00 invested in QBRP, one can save a NET $6.00 in capital road dollars over the life of the roadway
    • Performance life increase of 40% using pavement management, materials evaluations and quality assurance
    • Extending the life of the “good” roads, frees up extra funding for the “worst” roads
  • 36. Sustainable Quality Based Roads Program
    • Improve infrastructure asset value
    • Improve pavement condition system-wide
    • Make informed budgeting decisions
    • Better plan for upcoming work
    • Factual responses to the money managers and politics
    • Savings in long-term road capital improvement dollars, natural resources, greenhouse gases and emissions.
  • 37. Conclusion:
    • Sustainable QBRP pavements do not necessarily require “new technologies” – good old fashioned well built roads contribute to sustainability!
