Hiway Group is proud to have worked on an impressive range of unique projects over the past three decades, including highways, airports and foamed bitumen pavements.
Since 1986, through our expanding group of operational business units, our teams have collaboratively worked alongside Government departments, commercial organisations, land developers and main contractors.
The 6m wide existing pavement required a safety upgrade to enable the safe passage of tourism and logging traffic. Tenterfield Shire Council was seeking a best value for money alternative to maximise length of upgrade for the funds available.
Hiway Stabilizers was engaged by the client to provide a wide range of materials stabilisation and modification across a 27km greenfields four-lane motorway project including four new interchanges and two new link roads.
Pūhoi to Warkworth is the first of two stages for Ara Tūhono, an extension of Auckland’s Northern Motorway on State Highway 1. Hiway Stabilizers are working alongside NX2 to deliver both the stabilised Subgrade and Subgrade Improvement Layer for the 18.5km project.
Plant Mixed Foam Bitumen was produced and stockpiled at a nearby quarry, then hauled to the paving sites. The production target at the plant was to be a consistent 1500 tonnes per day with sufficient road haulage vehicles to ensure continuous operation of the paving operations.
