msr with cement treated subgrade
(OP)
hello,
first post. i've been asked to investigate the generally accepted range of values of MSR using a cement treated subgrade, with 7% and 12 inches deep. we can assume soft subgrade below the CTB. any help would be appreciated.
thanks,
scott

If the unconfined compressive strength of the CTB is over about 250 psi, shear and bending should control the design parameters, not the modulus value.
