Dear Azam Khan,
Although the
Marshall Mix Design method
has been used for many years, many engineers believe that the impact compaction used with the
Marshall method
does not simulate
mixture
densification as it occurs in real
pavement
.
Marshall
stability does not adequately estimate the shear strength of HMA.
Best wishes,
Poloju

There are also many advantages to using Marshall, particularly the relative simplicity of the equipment needed for design & testing. The FAA in the US still actively uses the Marshall method and has only recently moved to allow the Superpave method. If you require enhanced design testing, you can add Hamburg wheel tracking tests (rutting and stripping) and various cracking susceptibility tests to provide a more comprehensive design review to traditional Marshall designs. This complicates and increases the costs of the design phase, but are widely becoming the norm in the US.
