An eco-friendly water based bitumen emulsion suitable for dust
suppression on roads and broad acre applications
DustBloc is an eco-friendly bitumen emulsion that can be readily
diluted with water - at a suggested minimum of 20:1 and a suggested
maximum of 40:1.
When applied in these dilutions, the DustBloc solution soaks
into the ground and when the water evaporates, the bitumen is
released in an amount that is suitable for dust suppression. The
bitumen film is left to adhere to the dust particles.
This adhesion binds the dust particles together, makes them
heavier, and less likely to become airborne when disturbed by
vehicle traffic or wind.
A dust control process involves multiple sprays of DustBloc
building up the bitumen film on the particles with maintenance
sprays as required.
Normal application is done using a water-truck or spray units.
After use, the spray unit can be flushed with water, with no
There are no leaching issues with DustBloc, so it is safe to use
in eco-sensitive areas like national parks, coastal fringes and
livestock or agricultural farms.
