§490.307. National performance management measures for assessing pavement condition. — Inbound Citations

(a) The performance measures identified in § 490.307 are to be computed using methods in § 490.313 from the four condition metrics and three inventory data elements contained within the HPMS that shall be collected and reported following the HPMS Field Manual, which is incorporated by reference into this subpart (see § 490.111). State DOTs shall report four condition metrics for each pavement section: IRI, rutting, faulting, and Cracking__Percent. State DOTs shall also report three inventory data elements as directed in the HPMS Field Manual: Through Lanes, Surface Type, and Structure Type. All pavement data collected after January 1, 2018 for Interstate highways and January 1, 2020 for non-Interstate National Highway System routes shall meet the requirements of this section.

(a) The pavement measures in § 490.307 shall be calculated in accordance with this section and used by State DOTs and MPOs to carry out the pavement condition related requirements of this part, and by FHWA to make the significant progress and minimum condition determinations specified in §§ 490.109 and 490.317, respectively.

(i) 490.303 for the condition of pavements on the Interstate System measures specified in § 490.307(a)(1) and (2);

(i) If significant progress is not made for either target established for the Interstate System pavement condition measures, § 490.307(a)(1) and (2), then the State DOT shall document the actions it will take to achieve Interstate Pavement condition targets;

(2) For § 490.307(a)(1) the measure for percentage of lane-miles of the Interstate System in Good condition shall be computed to the one tenth of a percent as follows:

(1) The pavement condition metrics specified in § 490.311 that are necessary to calculate the Interstate System condition measures identified in §§ 490.307(a)(1) and (a)(2) and;

(i) 490.303 for the condition of pavements on the Interstate System measures specified in § 490.307(a)(1) and (2);

(i) If significant progress is not made for either target established for the Interstate System pavement condition measures, § 490.307(a)(1) and (2), then the State DOT shall document the actions it will take to achieve Interstate Pavement condition targets;

(3) For § 490.307(a)(2) the measure for percentage of lane-miles of the Interstate System in Poor condition shall be computed to the one tenth of a percent as follows:

(1) The pavement condition metrics specified in § 490.311 that are necessary to calculate the Interstate System condition measures identified in §§ 490.307(a)(1) and (a)(2) and;

(ii) 490.303 for the condition of pavements on the NHS (excluding the Interstate) measures specified in § 490.307(a)(3) and (4);

(ii) If significant progress is not made for either target established for the Non-Interstate System pavement condition measures, § 490.307(a)(3) and (4), then the State DOT shall document the actions it will take to to achieve Non-Interstate Pavement condition target;

(4) For § 490.307(a)(3) the measure for percentage of lane-miles of the non-Interstate NHS in Good condition in § 490.307(a)(3) shall be computed to the one tenth of a percent as follows:

(b) In accordance with the HPMS Field Manual (incorporated by reference, see § 490.111), each State DOT shall report to the HPMS no later than June 15 each year the pavement condition metrics specified in § 490.311 that are necessary to calculate the non-Interstate NHS condition measures in §§ 490.307(a)(3) and (a)(4).

(ii) 490.303 for the condition of pavements on the NHS (excluding the Interstate) measures specified in § 490.307(a)(3) and (4);

(ii) If significant progress is not made for either target established for the Non-Interstate System pavement condition measures, § 490.307(a)(3) and (4), then the State DOT shall document the actions it will take to to achieve Non-Interstate Pavement condition target;

(5) For § 490.307(a)(4) the measure for percentage of lane-miles of the non-Interstate NHS in Poor condition in § 490.307(a)(4) shall be computed to the one tenth of a percent as follows:

(b) In accordance with the HPMS Field Manual (incorporated by reference, see § 490.111), each State DOT shall report to the HPMS no later than June 15 each year the pavement condition metrics specified in § 490.311 that are necessary to calculate the non-Interstate NHS condition measures in §§ 490.307(a)(3) and (a)(4).
