For a standard case with h = 8 inch and k = 100 psi, the corner deflection is 0.0353 inch under 18-kip single axle load and 0.0459 inch under a 36-kip tandem axle load. If predicted number of load repetition is 5x10⁶, determine the percent erosion damage under single- and tandem-axle load, respectively.

<Equations>
p = k×w
Rate of work, P = 268.7 ́(p²/hk^0.73)

Log N = 14.524-6.777(C1P-9.0)^0.103

where C1 = 1 for untreated and 0.9 for treated subbase
Percent erosion damage = 100 ́sum of (0.06ni/Ni) for all vehicle groups
