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”
And then…And then…
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
Do it the rightDo it the right WAY !

Quality Based Roads Program Elements
1. System level pavement management
Software-based or spreadsheet
2. Pavement materials evaluations and rehabilitation recommendations
Enforceable Hot Mix Asphalt construction specifications
3. 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

Cost Effective Maintenance Strategy
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

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

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

Causes of Pavement Failure
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

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

*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 “…doing it the right way”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

NE Local Road Pavement Performance Study 2002
Quality Based Road Program
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!
