ARRB Systems has developed the first fully integrated road surface and sub-surface condition assessment system, providing functional and structural data at highway speeds.

Road agencies across the globe have similar issues in relation to managing their networks with the major question being: How long will our pavements last and what is the optimal maintenance and rehabilitation strategy?  Determining a reliable remaining life of a pavement requires assessment of both the structural and functional condition.

Methods of measuring pavement deterioration have primarily focused on surface condition. For many decades structural condition assessment was based on stationary or slow-moving devices which could cause hazardous situations in normal traffic. Structural condition surveys using these devices, therefore, became less common, eliminating vital information about pavement structural life.  Combining the two assessment techniques have, until today, been impossible. ARRB Systems iPAVe technology changes this forever.

Having a complete dataset, incorporating information of the pavement above and below the surface, enables the road asset manager to better understand its condition. This dramatically improves decision making in managing the road network. Road agencies in North America, Europe, South Africa, China, Australia and New Zealand are now using iPAVe to collect millions of deflection basin results yearly, along with associated synchronized and simultaneous collected surface condition data.

The iPAVe collects all of the following information:

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