Given the following mean input values:

w$18=10,000,000$ ESAL,

R$=95\%,$

S$0=0\mathrm{.}35,$

roadbed MR$=10,000$ psi,

pi$=4\mathrm{.}5,$

pt$=2\mathrm{.}5.$

Determine the thicknesses of the asphalt and base layers assuming a minimum asphalt thickness of $4$ inches with a$=0\mathrm{.}44,$ and a single base course with a minimum thickness of $6$ inches with a$=0\mathrm{.}10,$ m$=1\mathrm{.}0,$ MR$=21,000$ psi.
