Robotic road flatness measurement, built with LTA Singapore.
IRIs is a smartphone-controlled robotic vehicle that performs automated road flatness measurement to the strictest authority standards. From trench reinstatement to new pavement acceptance, IRIs delivers flatness data without the wait, the rework, or the inspection bottlenecks. Winner of Singapore’s Minister’s Innovation Award for Robotic Technology.
Road Flatness Measurement
The acceptance test that decides whether the road reopens
Road flatness measurement evaluates the surface evenness of newly laid pavement against contractual or regulatory standards.
It’s the final gate between “construction complete” and “open to traffic” – and one of the most disputed phases of any road project.
mm-grade flatness proof
Standard flatness validation methods
3-meter straight edge
Manual, slow and inconsistent work
Rolling profilers
Equipment-heavy, expensive, requires trained operators
Third-party laboratory testing
Accurate but introduces multi-day delays
Each method creates the same problem: roads stay closed longer, contractors miss deadlines, and authorities deal with rework, disputes, and citizen complaints.
IRIs replaces all three with a single robotic system that delivers pass-or-fail results in real time.
The Problem
Every hour a road stays closed costs the city money
Utility trenching, resurfacing, and new construction all require flatness validation before traffic returns. Traditional inspection methods are slow, inconsistent, and create bottlenecks that push contractors past deadlines and authorities past patience.
The result: Rework, penalties, citizen complaints, and roads that fail inspection on the third or fourth try.
The Solution
One robot. One smartphone.
Millimeter-level precision
Captures pavement flatness data accurate enough for the world’s strictest acceptance criteria.
Smartphone
controlled
No proprietary controllers, no specialist operators. Any field engineer can run the test.
Real-time
pass/fail
Know on-site whether the section meets spec. No lab, no waiting, no surprise rejections after the road’s been laid.
Audit-ready
output
Reports formatted for direct submission to road authorities, with full data trails for dispute resolution.
Built With
Singapore’s Land Transport Authority
IRIs was developed under the guidance of LTA Singapore, one of the world’s most rigorous road infrastructure regulators.
The same standards that govern Singapore’s road network now govern every IRIs unit shipped, making it the only smartphone-controlled flatness measurement system validated by a Tier-1 transport authority.
Award: Minister’s Innovation Award for Robotic Technology Validated by: Land Transport Authority, Singapore
Deployment: Active across trench reinstatement and new construction projects in Singapore and beyond
Built For
Made for the people who decide when roads reopen
Utility contractors
Road construction firms
QA and audit consultants
Infrastructure project consultants
Road authorities and regulators
Key Features
Automated flatness measurement, end-to-end.
Automated robotic operation
IRIs drives itself across the test section. No manual measurement, no hand-rolled profilers.
Smartphone control
Any Android phone is the controller. No proprietary tablets, no licensed software dongles.
High-precision sensors
Millimeter-grade accuracy that meets or exceeds straight-edge and rolling profiler standards.
Real-time results
Compliance decisions on-site, before the inspection team leaves.
Configurable acceptance criteria
Set thresholds for any road authority’s standard — IRC, AASHTO, LTA, or custom regional specs.
Detailed reports
Full data logs, profile graphs, and compliance summaries exportable as PDF for direct submission.
Compact and portable
Fits in any service vehicle. Deployable on urban roads, expressways or trench sites.
Why IRIs
Outperforms Traditional Flatness Inspection
Faster project handover
Cut inspection time from days to hours. Roads reopen sooner, contractors meet deadlines, citizens stop complaining.
Eliminate rework
Real-time compliance results mean defects are caught before paving crews leave the site. No surprise rejections two weeks later.
Standardized accuracy
Robotic inspection eliminates the operator-to-operator variance that plagues manual methods. Every test is consistent.
Lower total cost
No senior inspector dispatch fees. No third-party lab charges. No multi-day shutdowns. The unit pays for itself within a handful of projects.
Audit-defensible
Every test produces a timestamped, geo-tagged data file. Disputes get resolved with data, not arguments.
Applications
One robotic flatness measurement system. Every paving scenario.
Utility trench reinstatement inspection
New pavement acceptance testing
Highway resurfacing quality control
Bridge approach slab validation
Airport runway and taxiway inspection
Industrial floor flatness measurement
Pre- and post-construction defect liability audits
Smart city infrastructure quality programs
