    Quality Based Road Program Quality Based Road Program Presentation Transcript

    • 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 .
    • Sustainable Pavement Management Practices
      • Recycling
      • Warm Mix Asphalt
      • Porous Pavement
      • Pavement Preservation
      • Smooth Pavements
      • Longer Lasting Pavements
    • 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”
      • 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 !
    • Quality Based Roads Program (QBRP) 1. Pavement Management 2. Pavement Materials Evaluations 3. Construction Quality Assurance
    • 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
    • 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
        • Windshield
        • Video

    • 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

    • 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
    • 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
    • Typical Pavement Performance Curve Do Nothing Routine Maintenance Preventive Maintenance Structural Improvement Base Rehabilitation
    • Project Level Evaluation
      • Obtain available project information
      • Establish existing condition of pavement
      • Determine the cause of distress
      • Identify feasible alternatives
      • Make recommendations
    • Pavement Materials Evaluation
      • Obtain samples of subgrade/subbase, base and surface materials via test pits and cores
    • Pavement Materials Evaluation
      • Field samples are tested and evaluated in AASHTO accredited materials testing laboratory by certified technicians
    • 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
    • Causes of Pavement Failure Base related Age related Mix/Construction related
    • Pavement Materials Evaluation
      • Base/subbase materials are often recommended for reuse or alternative pavement solutions are suggested, saving money.
    • 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
    • Proper Design
      • Paving Mixture Design
      • Pavement Structure Design
      • Sustainable Pavement Alternative Selection
    • 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
    • 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

    • Annual Project Development
      • Diversify your investments
      Preservation Maintenance Structural Improvement Base Rehab *Miles per dollar spent
    • 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
      Paving Scheduled for Main Street
    • 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
    • 3. Construction Quality Assurance “…doing it the right way”
      • Assure pavement preparation:
        • Cracks sealed
        • Localized deficient areas properly patched
        • Correct application of tack
    • 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
    • Longer Lasting Pavements
      • Planned Work
      • Properly Designed
      • Enforceable specifications
      • Construction oversight for specification compliance
    • 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
    • NE Local Road Pavement Performance Study 2002 Quality Based Road Program $15/s.y. $2.75/s.y.
    • 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
    • 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.
    • Conclusion:
      • Sustainable QBRP pavements do not necessarily require “new technologies” – good old fashioned well built roads contribute to sustainability!
