Albany Highway Upgrade

Client: Main Roads WA & WA Stabilising
Location: Albany Highway, Western Australia
GCM mobilised a Wirtgen 2200 Surface Miner (2200SM) to progressively lower the crest of the existing Highway, directly adjacent to the open highway, in layers of 300mm. This enabled the work to be carried out with minimal disruption to traffic.

In addition the 2200SM was able to selectively separate spoil material from material that was suitable for use in the pavement layers in the widening areas. This resulted in significant cost saving to MRWA due to a large reduction in haulage costs, both to the spoil area, some 30km away and the basecourse borrow pit area, some 57km away.
