This techbrief provides information regarding the Federal Highway Administration's (FHWA's) issuuance of a Notice of Proposed Rulemaking (NPRM) to establish performance measures to assess the condition of the pavements on the National Highway System (NHS) and IHS in January 2015. And, in January 2017,  FHWA issued the Final Rule to implement the performance management requirements of MAP-21 and the Fixing America’s Surface Transportation Act. The performance measures established to assess pavement condition are the percentage of pavements on the IHS in good condition, IHS in poor condition, NHS (excluding IHS) in good condition, and NHS (excluding IHS) in poor condition. The condition of the pavements is to be determined based on the following condition metrics contained in the Highway Performance Monitoring System (HPMS): the International Roughness Index (IRI), cracking percent, rutting, and faulting.
