DF,
Fair enough for your "local airport", but the alleged damage at CB International was done in 2003. I am sure that the runway has not remained in use without repairs since then.
I still reckon that the damage more than likely occurred on the apron or turnoff point from the runway. Media reports often get it wrong.
Pavement concessions are generally only allowed within fairly tight parameters. IE if the stated limit PCN is exceeded by a factor of time or small magnitude in weight.
Can anyone from Canberra airport enlighten us?
