NTRO’s Infrastructure Measurement delivers services that provide the insight needed to plan, prioritise and manage your network with confidence.

Structural Assessment

See what's happening beneath the surface.

Surface condition only tells part of the story. Our structural assessment services reveal how pavements are performing beneath the surface, helping asset owners identify hidden weaknesses, predict deterioration and make more confident maintenance and renewal decisions before failures occur.

Does this sound familiar?
Roads are deteriorating sooner than expected, despite appearing to be in good condition.
Limited budgets mean every investment decision needs to be supported by reliable evidence.
Surface inspections alone don't provide enough confidence to prioritise maintenance and renewal.
Hidden structural issues can remain undetected until costly failures occur.
Reduce risk
Identify weak layers and emerging structural issues before they become visible failures or require major intervention.
Maximise every investment
Target funding where it will have the greatest impact, extending asset life and reducing whole-of-life costs.
Plan with confidence
Use trusted structural data and expert analysis to prioritise maintenance, renewal and long-term investment.
Understand pavement strength
Gain a clearer picture on how the pavement is carrying load and where weaknesses may be developing.
Dilapidation Surveys

Protect your assets before, during and after construction.

Independent dilapidation surveys provide an accurate record of infrastructure condition throughout the project lifecycle. By documenting asset condition before, during and after works, we help reduce disputes, protect stakeholders and provide confidence that infrastructure is being managed responsibly.

Does this sound familiar?
Construction activities are impacting surrounding roads and assets.
Independent evidence is needed to establish pre-construction condition.
Multiple stakeholders require confidence in condition reporting.
Post-construction outcomes need to be verified.
Establish a baseline
Document asset condition before works begin.
Validate outcomes
Compare conditions before and after construction.
Reduce disputes
Support transparent, evidence-based decisions.
Monitor with confidence
Track changes throughout the construction lifecycle.
Line Marking Reflectivity

Know when your line markings are performing.

Line marking reflectivity assessments measure how effectively road markings remain visible to drivers, particularly at night and in wet conditions. Our high-speed assessments help identify where remarking is needed, supporting safer roads and more effective maintenance planning.

Does this sound familiar?
You're unsure which line markings need remarking.
Night-time visibility is becoming a safety concern.
Manual inspections are time-consuming and inconsistent.
You need evidence to prioritise remarking programs.
Improve visibility
Identify markings that no longer meet performance expectations.
Survey efficiently
Assess large networks at normal traffic speed.
Support safer roads
Provide trusted data for safety-focused decisions.
Prioritise maintenance
Focus remarking where it is needed most.
Ride Quality

Keep your network running smoothly.

Ride quality assessments measure pavement smoothness to understand how roads are performing for users. The results support maintenance planning, network monitoring and construction quality, helping asset owners improve performance across the road network.

Does this sound familiar?
Road users are reporting poor ride comfort.
You're planning resurfacing or rehabilitation works.
Construction quality needs to be verified.
You want to monitor network performance over time.
Measure performance
Assess pavement smoothness consistently across the network.
Track change over time
Compare performance over time or after construction.
Support better journeys
Improve comfort and long-term network performance.
Prioritise improvements
Target resurfacing where it will have the greatest benefit.
Skid Resistance

Understand where grip matters most.

Skid resistance testing measures how well road surfaces perform in wet conditions, helping identify locations where reduced friction may increase risk. The insights support proactive maintenance and targeted safety improvements across the network.

Does this sound familiar?
High-risk locations require closer monitoring.
Surface friction may be contributing to safety concerns.
You need to prioritise treatments across the network.
Reliable evidence is required to support safety programs.
Identify higher-risk locations
Pinpoint areas where friction performance is reduced.
Plan proactively
Address issues before they become larger problems.
Maximise safety investment
Focus resources where they deliver the greatest benefit.
Support safer decisions
Target treatments using trusted evidence.
Unsealed Road Condition

Gain a clearer picture of your unsealed road network.

Understanding the condition of unsealed roads is essential for effective maintenance and long-term planning. Our assessments provide reliable condition data to help prioritise grading, identify deterioration and make better investment decisions across regional and rural networks.

Does this sound familiar?
Maintenance demands are increasing across the network.
You're unsure which roads should be graded first.
Funding decisions need stronger evidence.
Road conditions vary significantly across rural networks.
Understand network condition
Capture consistent condition data across unsealed roads.
Plan with confidence
Support long-term investment using trusted evidence.
Improve resilience
Make informed decisions for safer, longer-lasting roads.
Prioritise maintenance
Target grading and repairs where they're needed most.
