Suppose that, by using the asphalt layer design equation for Na and the appropriate

design chart, you find that the number of load cycles that will produce fatigue cracking

in the asphalt $($Na$),$ is $10,000,000.$ You found this using a design chart for a static vertical

wheel load of $39,000$ pounds. Further assume that a pressure transducer indicated that

there was near total unloading on the asphalt layer between axles loads. Find the

amount of cumulative loading from traffic $($in MGT$)$ that corresponds to this $10$ million

load cycles on the asphalt. $($Hint: use the equation you use to find, for example, N $=$

T$/(4*$Ps$)$ to solve for T in units of MGT$.$
