Road rehabilitation
Road rehabilitation is the term councils and Transport for NSW put in a tender.
What it is
It means restoring a pavement that has failed, structurally rather than just at the surface, to a condition that will carry its design traffic for another design life.
Accurate delivers it as one contract: assessment, stabilisation of the base, surfacing, and everything in between. That full scope is what makes it a rehabilitation rather than a patch.
How Accurate scopes it
Assessment to handover
Test pits or cores, a look at the drainage, and a read of the failure pattern. Where the client has a pavement design we work to it. Where they don't, we recommend one (binder, depth, surfacing) sized to the traffic and the budget.
Usually in-situ stabilisation of the base to 200–350mm, with a slag/lime or cement binder. Lime pre-treatment of the subgrade where it's wet or reactive. Deep-lift patching of any section too far gone to recycle.
A two-coat spray seal on a rural or lower-traffic road; an asphalt wearing course where the traffic or the client's standard requires it. Asphalt by Accurate's own crew; spray seal by Accurate's sealing partner, both under the one contract.
Compaction and strength test results, as-built depths and binder rates, and the documentation a council's asset register or a TfNSW QA system needs.

How we work with you
Full-service and part-service
Flexible ways to engage Accurate, depending on your project requirements.
Part-service
Plant and crew for the stabilisation step itself, working to your programme with your own resources alongside.
- Stabiliser, spreader truck and water cart
- Operators who know the plant
- Your compaction, trimming and surfacing
- The specialist step, on your dates
Cost efficiency
Same ground. Lower costs.
In-situ stabilisation reuses the material already in the ground, so there is no new material to import and no spoil to cart away. Less transport, less handling and a single mobilisation of plant make it a faster, more cost-effective way to rebuild a road.
Traditional approach
More transport. Higher costs. Longer program.
Import material
New gravel carted in from the quarry, load by load.
Export waste
The old pavement dug out and trucked away as spoil.
More plant and labour
Extra trucks, excavators and crew on site for longer.
Increased costs
Haulage, tipping and program time all add to the price.
In-situ stabilisation
Less movement. A smarter solution.
Reuse existing material
Stabilise on site, with nothing imported and nothing carted away.
Lower transport costs
Fewer truck movements, less haulage and less disruption to traffic.
Faster delivery
One pass of the recycler, compacted and back under traffic sooner.
What "rehabilitation" actually involves
A pavement fails from the bottom up. By the time a road is rutting, cracking in a crocodile pattern, or potholing repeatedly in the same place, the base has usually lost strength, often because water has got in and the subgrade has softened. A reseal or a thin asphalt overlay on top of that is a patch. It'll look fine for a season.
Rehabilitation means fixing the base. On most NSW council and state roads, that's in-situ stabilisation: recycling the existing base with a binder to a strength that carries the traffic, then surfacing it properly. Where the subgrade itself is the problem, it's lime treatment first, then the base. Where a section has failed completely, it's deep-lift patching or localised reconstruction.
The right answer depends on what's actually in the ground. So a rehabilitation job starts with finding out.
Why one contractor
Accurate self-delivers the scope
A rehabilitation job that's split between an assessment consultant, a stabilisation subcontractor, a surfacing contractor and a traffic management company has four places to slip and four people to call when it does.
One contractor
Assessment, stabilisation and surfacing under one contract.
Prequalified for the whole scope
Transport for NSW R2 road construction, alongside Z1 stabilisation and A2 asphalt.
Decisions on site
If the subgrade turns out wetter than expected, the decision is made on site, that day, by the site supervisor.

FAQs
Common questions.
01How does it help a council with a backlog?
Most NSW councils are carrying a rehabilitation backlog far larger than any single year's budget. The question isn't so much which roads need work as how much network can be treated per dollar. In-situ stabilisation is the answer to that question. At roughly half the cost of reconstruction and a fraction of the disruption, it lets a council rehabilitate two or three times the length of road for the same spend. That's why it's the method Roads to Recovery and disaster betterment funding increasingly favours, and why Accurate's Local Government Procurement approval and panel positions across the Hunter, Central Coast and Mid North Coast get used.
