HomeWelcome to the IRI Explorer. This website is for exploring and analyzing IRI data in the FHWA Long Term Pavement Performance (LTPP) database to gain insights into the factors that have historically governed and/or influenced the change in pavement IRI over time. The tools listed to the left can be used to explore the conditions and contexts under which different pavement designs and rehabilitation interventions have led to smoother pavements.
