Presented by Matthew J. LaChance Pavement Solutions for State, County, and Municipal Infrastructures
How Many of You… 1. Have the same, or less money to maintain your roads this year compared to last year? 2. Think the money you are receiving is enough? 3. Think you could be doing more with what you have to maintain you roads than you are currently doing?
Did You Know… 1. Your infrastructure is most likely your single largest asset. 2. You roadways are one of the few assets that near 100% of your tax contributors use on a daily basis. 3. Most of our roadway systems are under funded.
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… 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 right Do it the right WAY !
Failure Is Not an Option
1. Pavement Management 2. Pavement Materials Evaluations 3. Construction Quality Assurance Quality Based Roads Program
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 specifications 3. QA testing at the production facility and QA testing/inspection of in-place materials
Quality Based Roads Program Benefits 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
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

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
2. Pavement 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 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
Base related Age related Mix/Construction related Causes of Pavement Failure
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 Diagnose most probable causes of distress Identify structural characteristics and layer material properties in existing pavement Identify structural characteristics and layer material properties in existing pavement Economics Economics Recycling Recycling Emphasis on rehabilitation Emphasis on rehabilitation Place materials engineer in the best possible position to make correct choice of pavement rehabilitation Place materials engineer in the best possible position to make correct choice of pavement rehabilitation
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, provides Life Cycle Cost Analysis (LCCA) of pavement alternatives to determine both initial and life-cycle construction and maintenance costs Cost to benefit ratio (The Human Factor)
Project Specifications Develop specifications for quality enforcement, provisions for production quality and field placement quality specific to the owner’s needs Include Superpave hot mix asphalt, mat and joint density with incentive/disincentive
“…doing it the right way” 3. Construction Quality Assurance “…doing it the right way” Assure pavement preparation Assure production plant testing/inspection Assure field application through testing/inspection
Preservation Maintenance 100 93 85 72- 78 60- 65 Preservation Maintenance 0 Pavement Materials Evaluations have saved 10-40% in rehabilitation capital costs
Why Do All This? Do Nothing Routine Maintenance Preventive Maintenance Structural Improvement Reconstruction 100 93 85 72- 78 60- 65 Preservation Maintenance 0 Pavement Materials Evaluations have saved 10-40% in rehabilitation capital costs
$15/s.y. $2.75/s.y. 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 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
