The International Roughness Index (IRI) is an essential parameter for assessing pavement quality on roads. This indicator provides information about the surface irregularity, directly affecting travel comfort and pavement durability. Precise measurement of the IRI is carried out using specialized equipment such as Fiona I, Fiona V, and a Profiler.
Fiona I and Fiona V are advanced tools that employ technologies such as laser scanning and high-resolution cameras to assess pavement texture and roughness. These devices collect detailed data that contributes to the accurate determination of the IRI. Additionally, the Profiler is another valuable tool that measures the road's elevation along its length, allowing a comprehensive evaluation of its profile and the generation of the IRI.
The combination of these tools provides highway authorities with a complete insight into pavement quality and its impact on the driving experience. The information obtained through IRI measurement with Fiona I, Fiona V, and a Profiler is essential for planning maintenance and rehabilitation interventions, ensuring safer and more durable roads.
