New Bitumen Tank for South Island

New Bitumen Tank for South Island

12 April 2022

Today we would like to celebrate the commission of large bitumen tank at the Port of Lyttleton - Road Science has invested in this tank to bolster onshore storage and enable a secure supply chain.
The bitumen tank is a repurposed oil tank, and took the team 18 months to convert. It has five million litres of storage for the substance that shapes New Zealand’s roads and pavements.
“The new tank increases onshore storage space significantly for the South Island, building resilience for our business and ensuring supply certainty for the entire roading industry,” Doug Carrasco
