From page 5...
... Typically, fatigue data are analyzed by plotting the number of cycles to failure versus the maximum tensile strain or stress in the HMA specimens. It has been shown that plotting these data on a log-log (log of cycles to failure versus log of applied stress or strain)

From page 6...
... Beam fatigue testing was conducted at progressively lower strain levels until a fatigue life in excess of 50 million cycles was achieved. Data from the Long-Term Pavement Performance (LTPP)
