We currently operate nine permanent and one mobile production plant.
Higgins has been manufacturing its own asphalt since the '70s. Today, our capacity ranges from 600 to 1,000 tonnes per day. Each plant utilises the latest technology to blend and mix aggregate, bitumen, modifiers, polymers, fillers, and pelletised fibre.
Higgins covers the complete spectrum of asphalt mixes – from hard-wearing rut resistant mixes like SMA (stone mastic asphalt) to open mixes designed for lower noise and better water dispersion.
Every plant is operated to ISO9001 and the Roading New Zealand-governed Asphalt Plant Accreditation Scheme (APAS). Higgins undertakes in-house quality control through its IANZ-registered laboratories, which design all formulas and test samples to ensure they meet quality and performance specification.
Higgins is also among the leaders in recycling of existing asphalt surfaces for further roading use as part of its sustainability program.
