Putting AM2 on a road surface rather defeats the object, I would have thought. I imagine that those strips would fairly rapidly be identified by the bad guys and taken out. There is also the support train to consider. This was established and exercised continuously in RAF(G) with the Harrier Force and worked very well BUT it was expensive in both manpower and logistics, requiring extensive Royal Engineer, Tac Supply and Royal Signals support.
The Germany exercise sites were mainly grass, although PSA1 matting was also used over plough or soft ground. The war sites were exclusively hard surface and mainly 32’ wide roads, with provision of a 60’ square VL pad close to the aircraft hides. These hides and the admin/support areas were normally located in an industrial or residential setting, which would be tricky on a motorway.
Methinks it is someone’s “good idea” (rather like the Jaguar episode) and not a serious concept.
