National performance management measures for assessing pavement condition.

(a) To carry out the NHPP, the performance measures for State DOTs to assess pavement condition are: (1) Percentage of pavements of the Interstate System in Good condition; (2) Percentage of pavements of the Interstate System in Poor condition; (3) Percentage of pavements of the non-Interstate NHS in Good condition; and (4) Percentage of pavements of the non-Interstate NHS in Poor condition. (b) State DOTs will collect data using the methods described in § 490.309 and will process this data to calculate individual pavement metrics for each section of pavement that will be reported to FHWA as described in § 490.311. State DOTs and FHWA will use the reported pavement metrics to compute an overall performance of Good, Fair, or Poor, for each section of pavement as described in § 490.313.
