Auckland Airport Runway Project
Auckland Airport Runway
IN late April and early May Firth Concrete supplied around 10,000 cubic metres of concrete for the replacement of sections of the main runway at Auckland Airport.
The project was undertaken for Auckland International
Airport Limited by Brian Perry Civil and Kaipara Ltd. Kaipara
Ltd excavated the existing 305mm runway pavement, while
Brian Perry Civil laid the new 500mm pavement with a 28
day compressive strength of 52mpa. The concrete requires a
flexual strength of 5.3mpa and a compressive strength of
50mpa at seven days.
Over a two week period the 10,000 cubic metres of
concrete was supplied around the clock from an onsite
batching plant with product from Golden Bay Cement and
Winstone Aggregates.
Maintenance is ongoing on the Auckland International Airport runway.
The ends of the runway are replaced while the runway remains in use.
However, replacement of the midsections requires the main runway to be
closed. The alternative runway, 05L/23R, which is usually used for the
planes to taxi before take-off, becomes the runway when the main runway
05R/23L is closed.
Another midsection of the main runway was replaced approximately two
years ago. The entire runway replacement programme takes over six
years.
