The PCN value for 06/24 at EDI is 74/R/C/W/T.
The ACN value for a 777-300ER for a Rigid pavement with subgrade C at maximum mass is 109. For mimimum mass the corresponding value is 34.
Therefore, as the ACN value is greater than the PCN value a 777-300ER could not operate at maximum all up mass. To get an ACN value of 74 on that runway would restrict the take-off mass to 610,000 lbs - 167,000 lbs less than the certified maximum mass for a 777-300ER!
So the anwer to your question is YES.
But then again, even if the runway was stronger - it is not long enough! For sea level at ISA a 777-300ER at maximum take-off mass requires a "take-off field length" of just over 3000 metres. 06/24 only has an ASDA of 2614 metres. This would restrict the take-off mass to about 710,000 lbs.
But the runway strength remains the limiting factor!
