P is the relative dynamic modulus of elasticity (%) in the cycle

N is the number of cycles at which P reaches a predetermined minimum value to interrupt the test or the number of cycles at the end of exposure to freeze-thawing

M is the number of cycles at the end of freeze-thaw exposure

On the other hand, the mass change rate of the specimen in n freeze-thaw cycles is calculated by the following equation for each cycle.

Rate of mass change = (w-w _n ) / w × 100 (%)
