iPAVe

Full product specifications

The need for speed (and data). The intelligent Pavement Assessment Vehicle is the first and only comprehensive pavement measurement system in the world, providing structural and surface condition data at highway speeds.

Key benefits

  • Powerful tool to manage the condition, maintenance and lifecycle of road networks
  • Collects all pavement surface and structural parameters with high accuracy in one pass
  • Ability to operate at traffic speeds, improving production, safety and efficiency
  • Cost efficient, rapid data collection without the need for traffic control
  • Continuous measurements at higher resolution than traditional means (e.g. FWD)
  • Provides comprehensive data to make truly informed decisions on the type of rehabilitation and surfacing treatments required

Product applications

The iPAVe collects the following information:

  • Continuous pavement deflection 
  • Pavement surface condition, including:
    • Cracking
    • Roughness (IRI)
    • Texture (MPD and SMTD)
    • Rutting
  • Geometry (slope, crossfall, gradients)
  • Spatial location (GNSS)
  • Asset inventory imaging

Product features

  • Powerful tool to manage the condition, maintenance and life-cycle of road networks
  • High resolution detail and accuracy enables both project and network level analysis 
  • Fully synchronized structural and surface condition and imagery measurements enable comprehensive forensic analysis of pavement failures 
  • Assists in identifying the cause of a pavement failure, and what treatment is (or is not) required
  • Ability to determine the structural properties of the pavement including subgrade modulus, pavement modulus, and effective structural number 
  • Capable of collecting structural capacity of entire networks in just weeks, that would take decades via traditional means 
  • Interchangeable, scalable and identical Hawkeye outputs enables flexibility and optimization in network survey coverage 
  • Safety is significantly increased for operator and the road user

iPAVe data in action

The iPAVe provides continuous pavement deflection profiles, from which bearing capacity indices can be derived and pavement fatigue can be estimated. The high accuracy and resolution of the iPAVe data enable engineers to pinpoint areas where the pavement structure may be subject to failure, providing an additional dimension for pavement evaluation.

The below image shows a newly paved surface on a 16 mile sample of road. A thin overlay was completed along the first 12 miles, due to high levels of roughness, rutting and cracking. However, the iPAVe data shows there are two underlying pavement structural problem areas which will lead to premature failure of the road. Had this pavement been structurally evaluated before the overlay, full rehabilitation could have been performed in these areas to provide a more effective treatment solution.
