Pavement Condition
- The Federal Government uses the International Roughness Index (IRI) to measure pavement condition
- States are required to annually report IRI data to the FHWA for select road types
- An IRI score of <95 is good
- An IRI score between 95 & 170 is fair
- An IRI score >170 is poor
