The first slag asphalt road has been laid in the City of Port Phillip, South Melbourne (Australia), as part of Victoria state’s environmental policy to use more recycled materials in building and infrastructure projects. It is expected further sections will be laid in coming weeks in the City Area, with plans to install sections in some major freeway and infrastructure projects, such as the M80 ring road upgrade.

The project involved significant testing of materials and liaison with key stakeholders such as the State Highways authority (VicRoads) and the steel mill. Dan Cartwright, Harsco Metals Business Development and Technical Manager said: “The key to the project has been doing the hard work of testing the materials to prove the benefits of EAF slag in asphalt. Initial performance tests in Victoria provided excellent results, giving confidence to the local councils and approval bodies, backed by a major ANZ infrastructure group. We could also call on the group knowledge of Harsco in developing slag roadmaking projects in other countries. Going forwards, we hope other opportunities will come to fruition in Australia, when further trial sections and comprehensive utilisation projects planned in the coming months”.
