  1. Welcome to the Eastern Region LaboratoryProcedures ManualERLPM Guillermo Felix FAA – Eastern Region Paving Engineer March 17-19, 2008

  2. Workshop Objectives • Present concept for pavement design and the structural function of various layers • Present an understanding of material characteristics and principles for mix design to satisfy loading and environmental conditions. Marshall design and Superpave • Discuss purpose and principles to measure the quality of mixing and placing asphaltic materials (Quality Assurance)

  3. Workshop objectives • Discuss principles and practices for sampling and testing bituminous mixes • Explain statistical methods to determine quality of materials and pay factors • Present Contractor testing to control the quality of the mixes (Quality Control) • What happen after this workshop?

  4. Criteria for Pavement Design • Loads: Expressed in aircraft weight and • Aircraft annual departures (passes) • Soil strength: expressed as a relation to a standard soil for flexible pavement design. California Bearing Ratio (CBR)

  5. Surface course, P-401 Base course –stabilized or not Sub base course Sub grade – prepared support

  6. Aircraft weight for P-401 • Less than 12,500 (Highway Spec) • 12,500 lbs. but less than 60,000 Lbs. • 60,000 Lbs or more

  7. WHAT IS P-401? Surface course and defined by AC 150-5320-6 Specification that details de quality of the surface course

  8. What is P-403? • Specification for Stabilized Bituminous Base Course • Binder Course • Truing and Leveling Courses • Testing requirement has been reduced

  9. What is the ERLPM • Eastern Region Laboratory procedures Manual • Born in the Eastern Region to use statistical methods to determine quality vs range or media (average) • Origen – Military specs, now MS-2 • Document to be used in combination with P-401. required in Eastern region • Provide forms for project submittal - Appendices

  10. AGENDA • Mix Design – Jim Smith/Chris Brower/Rodney Joel • Random Sampling- Guillermo Felix • Quality Acceptance (Marshall) – Ken Rowbotham • Statistical Analysis – Carl Steinhauer • Computer Software – Guillermo Felix • Contractor’s Quality Control – Cindy LeFleur • ERLPM Test and List - Guillermo

  11. How many of you are • Consultants? • Testing laboratories? • Contractors? • Material supplier? • Government?

  12. Questions? Let’s welcome Jim and Chris
