Asphalt Resurfacing & Overlays. Central Coast NSW
When sealcoat won't save it, resurfacing will. We mill the worn top off, lay 25-50mm of fresh AC10 or AC14 hot-mix, and roll it to spec. Smooth black surface, 10-15 year life on residential, 15-20 on commercial. Driveways, carparks, council roads.

What Is Asphalt Resurfacing
Resurfacing means laying a new wearing course of hot-mix asphalt over the existing pavement. Two methods: overlay (lay 25-50mm of AC10 or AC14 straight on top) or mill-and-overlay (cold planer grinds off the worn top first, then overlay). Bigger fix than sealcoat. Restores surface fully. 10-15 year life on residential, 15-20 on commercial.
Mill-and-overlay
Cold planer removes worn top 25-50mm. Fresh AC10 or AC14 paved + rolled in its place. Keeps levels so doors and kerbs still meet. Used on carparks and roads.
Overlay only
Lay new asphalt straight over existing. Quick, cheap, fine when levels can rise 25-40mm. Good for driveways where the base is sound.
AC10 / AC14 hot-mix
AC10 dense-grade for driveways and light traffic. AC14 for carparks and heavier traffic. Rolled to spec density. Smooth black surface.
10-15 year life
Residential driveway 10-15 years on a fresh overlay. Commercial carparks 15-20 with a maintenance program. Council roads designed to spec.
Drainage fix
Resurfacing is the chance to re-grade and fix pooling. We adjust falls to drain water away from buildings before laying.
ITP signed off
Compaction densities, levels, falls and finished thickness all recorded against the spec. Paperwork supplied for council, strata and developer jobs.
When to Resurface Instead of Reseal
Resurfacing costs more than sealcoat but lasts 3-4x longer. If any of these match, it's a resurface job.
Alligator cracking
Network of cracks looking like crocodile skin. Base layer has failed. Sealcoat won't help. Mill-and-overlay needed.
Cracks wider than 6mm
Beyond sealable. Hot-pour sealant won't bond properly. Time for a new wearing course.
Pooling water
Surface no longer drains. Re-grading needs a fresh overlay to set new falls.
Aggregate raveling
Loose stone coming off the surface. Binder has fully oxidised. Sealcoat too late.
Worn through to base
Carparks with visible road-base showing through. Need fresh wearing course before vehicles damage the structure.
Rutting on roads
Wheel-track grooves. Indicates pavement deformation under load. Mill-and-overlay fixes the levels.
The BWB Resurfacing Process
Same crew does the quote, the prep, the paving and the roll. No subbies on the critical path.
Site assessment
Walk the pavement. Check base condition, drainage, levels. Decide overlay-only or mill-and-overlay. Written scope and price within 48 hours.
Mill or prep
Cold planer grinds off worn top course where needed. Sweep, blow clean, tack coat the prepared surface so the new layer bonds properly.
Pave AC10 or AC14
Hot-mix delivered straight to site. Paver lays to thickness in one pass where possible. Joints rolled in while mix is hot.
Roll to spec
Multi-tyre and steel-drum rollers compact the mix to target density. NATA-tested cores on commercial and council jobs.
ITP + sign-off
Inspection and test plan covers compaction, thickness, levels and falls. Documented for strata, developer and council clients.
Drive in 24 hours
Walk on immediately. Light vehicles 24 hours. Heavy trucks 48-72 depending on mix temperature on the day.
Cost & Timeline
Resurfacing is roughly 3-5x the cost of a sealcoat but lasts 3-4x longer. Exact written quote after site visit.
Residential driveway
Average Central Coast driveway. Overlay-only typically a 1-2 day job. Mill-and-overlay 2-3 days. Back in service 24 hours after final roll.
Strata / small carpark
20-40 bay carpark. Two to four days on site. Programmed by zones to keep half the carpark open. Weekend or overnight available.
Council road / large commercial
Lane-by-lane traffic management. Documented to RMS or council spec. NATA compaction results supplied. Defects liability 12 months.

Resurfacing questions, answered
When should I resurface vs reseal my driveway?
Reseal every 3-5 years when surface is still sound. Resurface when cracks are wider than 6mm, you can see stone aggregate, or sections are alligator-cracked. Resurfacing lays a new 25-50mm wearing course of AC10 or AC14 hot-mix and lasts 10-15 years.
What is mill-and-overlay?
A cold planer machine grinds off the top 25-50mm of worn asphalt. The fresh AC10 or AC14 hot-mix is then paved and rolled over the prepared base. Keeps existing surface levels so doors and kerbs still meet. Used on carparks, roads and large driveways.
How long before I can drive on it?
24 hours minimum, 48 hours preferred for full cure. We program around your access needs.
How thick is a resurfacing overlay?
Residential driveway 25mm typically. Commercial carpark 40mm. Council road 50mm or more with a regulating layer below. Thickness is set by traffic load and existing pavement condition.
How long before I can drive on a fresh overlay?
Walk on immediately. Light vehicles 24 hours after final roll. Heavy trucks 48-72 hours depending on mix temperature and ambient conditions on the day.
