Conversion Factors: Degrees C = degrees F - 32/1.8, Megapascals = 0.006894 PSI
given in Table 11-15. The plot of the subgrade damage factor versus thickness is given in Figure 11-20.
From the plot, it is determined that a 345-millimeter (13.5-inch) ABC pavement would satisfy the
subgrade criteria. The asphalt fatigue damage factor for a 330-millimeter (13-inch) pavement was
computed to be 0.24, thus determining that the 345-millimeter (13.5-inch) pavement satisfies both
criteria.
