K$-$value can be empirically converted into the resilient modulus as described in

AASHTO $(1993)$

The diameter of loading plate is $30$ in and was determined from a simulation

under the modern heavy traffic.

The modulus $K($K$-$value$)$ is calculated from the ratio of unit load on the plate to

the deflection of plate.

Resilient modulus is based only on the recoverable strain under repeated loads.
