Job:
The upgrade of the Ipswich motorway has been a landmark infrastructure project in Queensland during 2009 to 2010.

An Aran paste backfill plant (MODUMIX II-P) was used to produce mine fill paste and slurry for filling abandoned underground coal mine stopes and tunnels which lay under the new motorway alignment.

Backfill was delivered around the construction site in mixer trucks for pumping underground. The backfill product was based on flyash reclaimed from a local thermal power station, crusher dust, cement, and treated water.

Highly fluctuating moisture contents in the flyash were accommodated in Aran’s intuitive computer control system.
