iPAVe
An engineering masterpiece.
Intelligent Pavement Assessment Vehicles (iPAVE) are a prime mover and trailer equipped with a heavy weight over a single rear axle.
A series of lasers mounted in the trailer measures the deflection velocity of the pavement in the left-hand wheel path as the truck travels down the road at highway speeds.
This information is used to assess the bearing capacity of the pavement. It is predominately used for state road authorities but has been utilised on some local government networks too. iPAVE vehicles can also measure roughness, texture, rutting, digital imagery for visual rating and ACD cracking.

Next-generation radar technology.
It collects all data as it drives, including video imagery, to monitor the response of a pavement when placed under load. Several cameras are mounted to the iPAVE to collect asset and pavement imagery.
Data provided includes continuous pavement deflection profiles, from which bearing capacity indices can be derived and pavement fatigue estimated. The high accuracy and resolution of the iPAVE enables engineers to pin-point areas where the pavement may be subject to failure, allowing local government and road agencies the opportunity to decide where best to spend their valuable maintenance dollars.
ARRB has three iPAVE vehicles, which are available to local government and road agencies. Our third iPAVE vehicle joined the fleet in July 2022. You can find out more about our newest iPAVE, with ground penetrating radar, in the video below.

Benefits
- Collects pavement condition and structural parameters in one pass
- Ability to operate at traffic speed
- Increased operator and road user safety
- More data measurements than traditional methods (i.e. FWD)
- More cost efficient as no traffic control is required
- More flexibility in survey planning and network coverage
Hawkeye Integration
The Traffic Speed Deflectometer (TSD), manufactured by Danish company Greenwood Engineering, has been fully integrated into ARRB's Hawkeye platform.
Additional Hawkeye sensors are fitted to the iPAVE for measuring roughness, rutting, texture and automated cracking.
Several cameras can also be mounted to collect asset and pavement imagery.
The ARRB Hawkeye platform's unique acquisition and processing software fully synchronises all data streams ensuring structural and surface condition measurements are time-stamped and measured simultaneously.
