Dust suppression treatment involves the laying of profiling material and then a spray seal of emoleum. Whilst this may give the appearance of bitumen, it is only a temporary dust suppression measure (lasting up to 5 years) and not a bitumen finish. The road remains classed as an unsealed road.
Unfortunately, road profiling materials are no longer available and Council has discontinued the dust supression program.
Council is exploring alternative treatment options and will continue to grade unsealed roads in the meantime.
