Frost penetrates under pavement much deeper than say, in your lawn. Loam and grass act as an insulator of sorts. In this case, however, even with the extreme cold of a couple of weeks ago, I would find it hard to believe the frost could penetrate 4 feet. You've got a problem with that pipe and I would suspect it might be a little too flat, meaning not enough pitch to keep the effluent flowing. Most septic systems today are constructed with schedule 40 pipe. It doesn't "sag" unless installed improperly.
