5. Current Projects – Construction Cycle 7: Asphalt
Primary Objectives
Perpetual Pavement Tests. Develop “perpetual pavement” design criteria for airport pavements.
Overload Tests. Determine allowable aircraft overload criteria for flexible pavement.
Secondary Objectives
Study the structural performance of drainable bases.
Investigate changes in subgrade CBR with moisture movement in low strength subgrade.

6. CC7 Test Item Layout

7. CC7 Perpetual Pavement Test Fiber-Optic Strain Plate Responses
Fiber-Optic Strain Plates
White Light Polarization Interferometry
Software interprets and transforms the received signal into physical quantitative values.
Measurement of near-surface compressive & tensile strains, and tensile strains at the bottom of the AC, over an 18-inch width.
HMA strain measurements made during traffic tests (now in progress) will be used to validate the new HMA fatigue failure model in FAARFIELD.
