  1. “QUALITY MANAGEMENT” THE EARLY YEARS 1986-1992 TIMES – THEY ARE A CHANGIN’ - BOB DYLAN Asphalt Conference December 2, 2003 Doug Schwartz PE Concrete Engineer

  2. Design TOTAL QUALITY MANAGEMENT CONTINUOUS IMPROVEMENT Products Performance Placement

  3. IMPLEMENTING A QM PROGRAM • FORM A TASK FORCE • VISIT OTHER STATES • EXECUTIVE SEMINARS

  4. QUALITY MANAGEMENT WORK PLAN • DEVELOP TEST PROCEDURES • TRAIN PERSONNEL • DEVELOP SPECIFICATIONS

  5. LONG RANGE GOALS • DEVELOP AND IMPLEMENT QUALITY MANAGEMENT PROGRAM TO ASSURE CONSTRUCTION OF QUALITY ASPHALT PAVEMENTS

  6. 1986 OHIO TRIP – LOOK TO OTHER STATES FOR HELP

  7. Mn/DOT DISTRICT BITUMINOUS MIXTURE TESTING LABORATORIES

  8. DR. DICK SMITH - CONSULTANT TECHNICAL ADVISOR ASSIST IN: - SPECIFICATIONS - DATA ANALYSIS - TRAINING

  9. EXECUTIVE MIX DESIGN SEMINARS

  10. SPECS, SPECS AND MORE SPECS

  11. VISIT IOWA TO REVIEW THEIR TECHNICAL CERTIFICATION PROGRAM

  12. CERTIFIED TECHNICIANS • THE NEED FOR CERTIFIED TECHNICIANS GREW AS A RESULT OF THE Mn/DOT QUALITY MANAGEMENT ASPHALT PROGRAM

  13. CERTIFIED TECHNICIANS • THE PROGRAM WAS EXPANDED TO INCLUDE OTHERCONSTRUCTION AREAS IN 1989

  14. CERTIFIED TECHNICIANS BY THE EARLY 90’S , 2000 TECHNICIANS HAD GONE THROUGH VARIOUS BITUMINOUS CLASSES TECHNICIANS FROM: Mn/DOT CITIES/COUNTIES CONTRACTORS CONSULTANTS PRIVATE TESTING FIRMS

  15. CERTIFIED TECHNICIANS PROGRAM EXPANDED TO OTHER AREAS: CONCRETE BRIDGE CONSTRUCTION GRADING AND BASE SIGNAL & LIGHTING

  16. BEFORE QM PROGRAM ACCEPTANCE BASED ON AGENCY TESTS ONLY QA + IAST QM PROGRAM CONTRACTOR TESTS USED AS PART OF THE AGENCY ACCEPTANCE PROCESS QM = QC + QA + IAST QM – A SHIFT IN AGENCY ACCEPTANCE PARADIGMS

  17. QUALITY MANAGEMENT PROGRAM CONTRACTOR DESIGNS BITUMINOUS MIXES AT 4 % AIR VOIDS Mn/DOT VERIFIES CONTRACTOR’S MIX DESIGN

  18. CONCEPT OF QM CONTRACTOR TESTING BENEFITS • Allows Contractor Ingenuity • Reduces Litigation • Use of Materials and Resources • Contractor Control of Operations • Incentive for Timely Test Results • Tests More Closely Measure Quality • Reduce Extraction Tests

  19. CONCEPT OF QM CONTRACTOR TESTING BENEFITS (Con’d) • Evaluate All Mixtures • Everyone Involved in Production and Placement Process QC • Improves Asphalt Mix Design • Reduce Construction Time – Less Delay • Reduce Need for Seasonal Workers • Reduce Duplication of Testing • Improves Pavement Performance

  20. CONTRACTOR TESTING

  21. QM CONTRACTOR’S TESTS • AC CONTENT BY SPOT CHECK • GRADATION OF VIRGIN AGGREGATE • MIXTURE PROPERTY TESTS: • Marshall Gravity • Maximum Gravity • Calculate % Air Voids • EXTRACTION AND GRADATION FOR TYPE 32 & 42 • % AIR VOIDS IN CORES FOR SPECIFIED DENSITY

  22. CONTROL CHARTS

  23. 2 PILOT PROJECTS

  24. 5 PROJECTS

  25. 12 PROJECTS

  26. 33 PROJECTS

  27. BITUMINOUS QUALITY MANAGEMENT PROGRAM 1990 – 77 PROJECTS (APPROX. 90% OF BITUMINOUS PROGRAM) 1991 – APPROXIMATELY 90%

  28. PHASE II QUALITY MANAGEMENT • DENSITY • RIDE • SUPERPAVE
