and based on recommended value range of k value
then taken modulus of subgrade around 200 psi/in 2.4 SUBBASE based on AASHTO Design guide for design of pavement structure 1993, clause 1.6.2
since Total ESAL is

Since additional subbase doesn't needed refer to Code, then subbase layer will be provided with condition of CBR 20% below the Concrete pavement to achieve design strength requirement 2.5 LOAD TRANSFER COEFFICIENT
