I have a vague recollection that when the USAF resurfaced Pease Air
Force Base in Newington NH (just a few years before it was closed down
the surface mentioned was 36 inches of concrete.

That's the thickness of the resurface layer? I worked as a tunnel rat on the
expansion of Hartsfield in the 70's. The ramps were three layers of concrete, each
two feet thick.

As I say, the memory is ten or twelve years old. What a peaceful
summer it was! The KC-135s all flew off to New York state.

all the best -- Dan Ford
