Thank you 

Using the AASHTO design the procedure, determine the minimum depth of concrete pavement required for the design period of 20 years. (Assume Total ESAL =
31.91*10^6)
R=95%, So -0.3,
Cd = 1.0
J=3.2,
k- 130,
Ec = 5*10 lb/in.2
Sic =650 lb/in^2,
Pt -2.5
Pi 4.5
Select one:
a. Around 12 in
b. around 9 in
C. around 13in
d. around 7 in
