From page 91...
... • Considering a typical principal arterial traffic stream, the thickness of a perpetual pavement designed using PerRoad was similar to that determined using the 1993 AASHTO Pavement Design Guide or MEPDG (without the endurance limit) for a 20- or 40-year design life.

From page 92...
... Forensic investigations should be conducted on a stratified random sample of the thickest GPS-1, GPS-2, and SPS-1 pavements in the LTPP database that exhibit cracking, to determine the cause of that cracking. For pavements designed using equivalent annual or equivalent seasonal temperatures, the use of a single value for the endurance limit appears to be reasonable.
