Project Title:
  Validation Of Extended Life HMA Pavement Design Concepts
Start Date: 7/1/2002
End Date: 12/31/2006
Summary of Project:
  Twenty one IDOT mixtures have been sampled and tested for dynamic modulus and fatigue. Nine binder mixes have been tested for Rich bottom Binder fatigue characterization. Full Depth HMA sections have been constructed, instrumented, and response tested with the FWD and ATLAS machine. Fatigue testing of a thin section to failure has begun.
Objective of Project:
  This research will provide test data for dynamic modulus and fatigue for current IDOT mixes in accordance with the AASHTO 2002 data requirements for pavement design. The fatigue testing will validate fatigue algorithms and illustrate the existence and magnitude of a fatigue endurance limit. Constructed pavements will be tested for responses and fatigue behavior.
Expected Outcome:
  Background information will be generated that will allow an improved design procedure for Extended Life HMA pavements, with consideration of fatigue endurance limits to be developed.
