Formatted abstract
Damage to sealed flexible pavements due to heaving of the heavy clay subgrade, investigated at Julia Creek, Richmond and Winton Aerodromes in North West Queensland, is shown to be primarily a function of the geometric design, which makes run off water available to the moisture deficient subgrade.

The extent of the lateral transfer of water in the subgrade from the pavement edge, and the associated vertical swelling has been determined in the field, while laboratory tests have shown the subgrade swelling which may be expected if free water is available.

As the result of these experiments, suggestions are made for modifications to the present aerodrome design standards in their application to aerodrome pavements in the "black.soil" areas of Australia, and the need is stressed for the continuance of research into the swelling properties of these soils.
