Quality Based Road Program

  1. 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. 2. Sustainable Pavement Management Practices <ul><li>Recycling </li></ul><ul><li>Warm Mix Asphalt </li></ul><ul><li>Porous Pavement </li></ul><ul><li>Pavement Preservation </li></ul><ul><li>Smooth Pavements </li></ul><ul><li>Longer Lasting Pavements </li></ul>
  3. 3. Pavement Management Theory <ul><li>Do the right thing at </li></ul><ul><li>the right time in the right place </li></ul><ul><ul><li>Make timely maintenance repairs </li></ul></ul><ul><ul><li>Avoid more expensive, extensive repairs </li></ul></ul>Avoid “Worst First”
  4. 4. <ul><li>Do the right thing : correct preservation maintenance application, HMA mix, rehabilitation alternative </li></ul><ul><li>At the right time : pavement management system analysis </li></ul><ul><li>In the right place : pavement management in consort with a master plan, combining pavement sections, plus the human factor </li></ul>And then… Do it the right WAY !

  15. 15. 2. Pavement Materials Evaluation <ul><li>Preferred approach for pavements in need of capital repair </li></ul><ul><li>Provide owners/managers with the most cost effective and reliable rehabilitation alternatives for their pavements </li></ul>
  16. 16. Typical Pavement Performance Curve Do Nothing Routine Maintenance Preventive Maintenance Structural Improvement Base Rehabilitation
  17. 17. Project Level Evaluation <ul><li>Obtain available project information </li></ul><ul><li>Establish existing condition of pavement </li></ul><ul><li>Determine the cause of distress </li></ul><ul><li>Identify feasible alternatives </li></ul><ul><li>Make recommendations </li></ul>
  18. 18. Pavement Materials Evaluation <ul><li>Obtain samples of subgrade/subbase, base and surface materials via test pits and cores </li></ul>
  19. 19. Pavement Materials Evaluation <ul><li>Field samples are tested and evaluated in AASHTO accredited materials testing laboratory by certified technicians </li></ul>
  20. 20. Field Sampling and Testing For Pavements in Need of Capital Repair <ul><li>Diagnose most probable causes of distress </li></ul><ul><li>Identify structural characteristics and layer material properties in existing pavement for sustainable selection incorporating: </li></ul><ul><ul><li>Economics and Green Assessments </li></ul></ul><ul><ul><li>Recycling </li></ul></ul><ul><ul><li>Emphasis on rehabilitation, not reconstruction </li></ul></ul><ul><li>Place materials engineer in the best possible position to make correct choice of pavement rehabilitation </li></ul>
  21. 21. Causes of Pavement Failure Base related Age related Mix/Construction related
  22. 22. Pavement Materials Evaluation <ul><li>Base/subbase materials are often recommended for reuse or alternative pavement solutions are suggested, saving money. </li></ul>
  23. 23. Pavement Materials Evaluation <ul><li>Provides 5, 10, 20, 25+ year action plans for maintenance and rehabilitation of roadways and parking lots </li></ul><ul><li>If applicable, provide Life Cycle Cost Analysis (LCCA) of pavement alternatives to determine both initial and life-cycle construction and maintenance costs </li></ul><ul><li>If applicable, provide Life-Cycle </li></ul><ul><li>Sustainability Assessments </li></ul><ul><li>Cost to benefit ratio </li></ul>

  33. 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. 34. NE Local Road Pavement Performance Study 2002 Quality Based Road Program $15/s.y. $2.75/s.y.
  35. 35. The Payoff: <ul><li>For every $1.00 invested in QBRP, one can save a NET $6.00 in capital road dollars over the life of the roadway </li></ul><ul><li>Performance life increase of 40% using pavement management, materials evaluations and quality assurance </li></ul><ul><li>Extending the life of the “good” roads, frees up extra funding for the “worst” roads </li></ul>
  36. 36. Sustainable Quality Based Roads Program <ul><li>Improve infrastructure asset value </li></ul><ul><li>Improve pavement condition system-wide </li></ul><ul><li>Make informed budgeting decisions </li></ul><ul><li>Better plan for upcoming work </li></ul><ul><li>Factual responses to the money managers and politics </li></ul><ul><li>Savings in long-term road capital improvement dollars, natural resources, greenhouse gases and emissions. </li></ul>
  37. 37. Conclusion: <ul><li>Sustainable QBRP pavements do not necessarily require “new technologies” – good old fashioned well built roads contribute to sustainability! </li></ul>
