SYDNEY

METRO 2

This project involved the use of our CPT to cover 18km of paved tunnel to respond to the needs of Australia’s largest infrastructure proect, the Sydney Metro. The invert design allowed concrete to be supplied direct from the agitator and as such a 3 platform system was selected.
The machine improvements included hydraulic drives, telescopic axles, gantry frames and our significantly improved Screed. 18km of tunnel was paved, all well within the tight tolerance. As with Cross Rail, a high quality exposed aggregate finish was produced to accept the track slab. No re-work was performed.
