Trying to check the Airbus A400M for an airport pavement, I could find no ACN/PCN guidance or charts anywhere. So I have prepared some.
The A400M has a tridem undercarriage - two main gear legs with 6 wheels each. Main gear tyres are 43 x 15.5-17, at 1012 kPa pressure. Current MTOW is 141,000kg and empty weight is 76,500kg.
I calculated and drew ACN charts for the A400M, and they can be found here:

These charts are preliminary. There is no official data from Airbus or any other source, so I had to estimate gear spacing and load on main gear. There might also be some additional variability because of the unique kneeling landing gear. But at least these can serve as an interim guide.
Checking the ACNs against those for another 140tonne-class aircraft, the Boeing 767-200, I find that 767-200 on a C subgrade at 141 tonnes is ACN 43, and the A400M is ACN 30. That seems about the right order of difference.
