The following figure is a flexible pavement system with the resilient
moduli layer coefficients and drainage coefficients as shown. If the predicted ESAL
= 6x106, Reliability, R = 99%, Standard Deviation (So) = 0.45, and APSI = 2.5,
select thicknesses D1, D2, and D3 in accordance with the AASHTO Guide for
Design of Pavement Structures.
E₁ = 400, 000 psi; a₁ = 0.42, Thickness = D₁
E₂=30,000 psi; a₂= 0.14, m₂ = 1.2; Thickness = Dz
E=11,000 psi; a=0.08, m3 = 1.2; Thickness = D3
MR= 5,700 psi
(read image) (Answer: M motor = 0.836 Ib-ft, Mf = 0.1045 Ib-ft)
Please find the torsional yield strength, the yield strength, the spring index, and the mean diameter.
