Auckland Road Maintenance Alliance – West
New product innovations, recycling pavements to create emulsion treated basecourse and design alterations are all part of a new way of managing road maintenance.
Fiji International Airport
Tailoring a mix design to work with local aggregates (yet meet FAA standards for an emergency landing of an Airbus A380 at Fiji International airport) was critical to finding a solution for a cracking and delaminating runway.
Hampton Downs Race Track
Creating a single-layer asphalt paving solution for Hampton Downs race track, that had a high grip surface, was durable, yet flexible enough (due to the expected sub-grade settlement) lead to an international first - a single-layer asphalt track mix design.
Mercer Longswamp
Delays with the Mercer Longswamp section of the Waikato Expressway, meaning sealing had to take place in winter and the need for structural asphalt to tie in the old and new highway, demanded specific design parameters.
Milford Aerodrome Resurfacing
Resurfacing a highly trafficked airport runway at Milford Sound at a remote site in Fiordland National Park required the design of a new seal specifically developed for these climatic conditions.
Newmarket Viaduct
The development of ‘blonde asphalt’ as a solution for the Newmarket Viaduct mitigated temperature stresses allowing for an extended design life for the Viaduct.
West Waikato
High traffic counts and peaty Waikato soil were challenges with the West Waikato Roading Maintenance Contract. Bitumen and Pavement Limited developed a number of innovative asphalt designs using different types of binders, multi-coat seals, larger sized aggregate for chipsealing, to create more flexible and durable pavement designs in the West Waikato Roading Maintenance Contract.
