Just in case...
Maybe helpful for those gentlemen wanting to replicate self-made concrete hex slab airfield pavement:
(dimensions in red = 1/32nd scale)
The earliest precast hex slabs (r=1200mm, thickness 100-140mm) date back as far as 1931/1932.
As operational aircraft grew heavier, the edge length was increased to 1500mm, accordingly. Slab thickness icreased up to 220mm.
Also commonly found were hex slab sizes of 1800mm.
As previously stated in an earlier post, the concrete hex slabs started to be superseded by the rectangular PAG-type prestressed concrete slabs during the very late 1960s/early 1970s.
Time hack...Soviet style:
