USAF uses what curves for pavement evaluation reports?
Extended Life(Shattered Slab Criteria)
Type A Traffic Area is?
− First 1,000 feet at each end of the runway
− Primary taxiways
− Other sections of runway, if required for back-taxi operations
− All operational surfaces of semi-prepared or unsurfaced airfields
− All operational surfaces during an expedient airfield pavement
evaluation
Type B Traffic Area is?
-Aprons
Type C Traffic Area is?
Evaluate for nonchannelized traffic and 75% of design weight of aircraft.
− Center section of runway, if not required for back-taxi operations
− Secondary taxiways
− Overruns
Air Force evaluations are based upon extended-life criteria where Blank percent of the slabs are cracked into approximately six pieces at the end of traffic.
50%
A Blank inch(s) rut, measured on the surface, including both the permanent deformation and surface upheaval, but may be caused by failure of any layer within the pavement structure.

Primary function of asphalt
Wear/water resistance
larger load of A/C will do what to how many passes?
decrease passes
Traffic A has how many inches of wander on
