Asphalt Contractor
Auckland

The service life of an asphalt pavement depends on the pavement design, ground conditions, drainage, vehicle loading, asphalt thickness and ongoing maintenance. A residential driveway and a heavily trafficked commercial car park have very different requirements, so we do not apply one expected lifespan to every pavement.

Asphalt should not be placed when surface or weather conditions prevent proper preparation, bonding and compaction. Rain, a wet pavement surface or unsuitable temperatures may require paving to be postponed. We assess conditions before paving and adjust the programme where required.

Basecourse is part of the aggregate pavement beneath the asphalt surface. Its material quality, depth, compaction and drainage contribute to how the pavement carries traffic loads and maintains its shape. Premature pavement distress can result from a range of factors, including inadequate pavement depth, weak subgrade, poor compaction, drainage problems or loading beyond the original design.

The repair method depends on the extent of the failure and the condition of the pavement underneath. Localised failures are typically cut back to sound pavement, failed material is removed, the underlying base is repaired where required and the area is reinstated with asphalt. Wider cracking, deformation or recurring failures may indicate that resurfacing or reconstruction is more appropriate.

Yes. Where line marking forms part of the project, we can coordinate a specialist line-marking contractor so the surfacing and marking sequence is managed within the wider programme.

Sometimes. The existing pavement needs to be assessed for structural condition, levels, drainage, cracking and available finished height. Where the underlying pavement is suitable, milling and resurfacing or an asphalt overlay may be appropriate. Where failures extend into the basecourse or subgrade, those areas need to be repaired before resurfacing.

Asphalt thickness depends on the mix type, pavement design, intended loading and supporting pavement structure. A residential driveway, commercial car park and heavy-vehicle pavement may all require different asphalt layers and aggregate build-ups. We work from the project specification where one is provided, or confirm the proposed build-up as part of the pricing scope.

We inspect before recommending an approach. Patching suits localised damage over a sound base, and an overlay suits a worn or cracked surface over a stable base where levels allow the extra thickness at kerbs, garage doors and drains. Where the base has failed or drainage is the cause, replacement or a rebuild is usually needed.

It can work over a sound, stable slab, so we inspect the concrete before recommending it. Cracks and joints can reflect through the asphalt, and a moving or failing slab needs assessment first.

Where the layout allows, yes. We coordinate with all residents through the owner or body corporate, confirm which sections close and when, and stage the work so access is kept. Where that is not possible, closures are kept short and agreed with notice.

When traffic can return depends on conditions, the thickness laid and the loads involved. We advise on the day, based on those conditions.

Where the site allows, we can stage asphalt and associated civil works around the agreed access and operating requirements. We review work areas, traffic movements, deliveries and closure periods before confirming the programme. Some parts of the site may still need to close while work is carried out and until the surface is ready for use.
