Posttraffic Testing at the National Airport Pavement Test Facility: Test Item MFC

The conventional flexible pavement test item on medium-strength subgrade (MFC) exhibited ruts 4 to 6 inches (100 to 150 mm) deep with upheaval outside the traffic lane and asphalt surface (AC) cracking in the wander pattern. A trench was dug to conduct posttraffic investigation into the failure mechanism of the pavement structure.
