(1) Highway Performance Monitoring System (HPMS) Field Manual, IBR approved for §§ 490.103, 490.309, 490.311, and 490.319.

(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.

(b) The performance measure for pavements shall be calculated based on the data collected in § 490.309 and pavement condition metrics computed in § 490.311. The performance measure for pavements shall be based on three condition ratings of Good, Fair, and Poor calculated for each pavement section. The ratings are determined as follows:

(1) IRI rating shall be determined for all pavement types using the following criteria. If an IRI value of a pavement section is:—

(i) Less than 95, the IRI rating for the pavement section is Good;

(ii) Between 95 and 170, the IRI rating for the pavement section is Fair; and

(2) Cracking condition shall be determined using the following criteria:

(A) If the Cracking__Percent value of a section is less than 5 percent, the cracking rating for the pavement section is Good;

(B) If the Cracking__Percent value of a section is equal to or greater than 5 percent and less than or equal to 20 percent the cracking rating for the pavement section is Fair; and

(C) If the Cracking__Percent value of a section is greater than 20 percent the cracking rating for the pavement section is Poor.

(A) If the Cracking__Percent value of a section is less than 5 percent, the cracking rating for the pavement section is Good;

(B) If the Cracking__Percent value of a section is equal to or greater than 5 percent and less than or equal to 15 percent the cracking rating for the pavement section is Fair; and

(C) If the Cracking__Percent value of a section is greater than 15 percent the cracking rating for the pavement section is Poor.

(A) If the Cracking__Percent value of a section is less than 5 percent, the cracking rating for the pavement section is Good;

(B) If the Cracking__Percent value of a section is equal to or greater than 5 percent and less than or equal to 10 percent, the cracking rating for the pavement section is Fair; and

(C) If the Cracking__Percent value of a section is greater than 10 percent, the cracking rating for the pavement section is Poor.

(3) Rutting or faulting rating shall be determined using the following criteria.

(A) If the rutting value of a section is less than 0.20 inches, the rutting rating for the pavement section is Good;

(B) If the rutting value of a section is equal to or greater than 0.20 inches and less than or equal to 0.40 inches, the rutting rating for the pavement section is Fair; and

(C) If the rutting value of a section in is greater than 0.40 inches, the rutting rating for the pavement section is Poor.

(A) If the faulting value of a section is less than 0.10 inches, the faulting rating for the pavement section is Good;

(B) If the faulting value of a section is equal to or greater than 0.10 inches and less than or equal to 0.15 inches, the faulting rating for the pavement section is Fair; and

(C) If the faulting value of a section is greater than 0.15 inches, the faulting rating for the pavement section is Poor.

(4) The FHWA will determine that a reported section in HPMS has a missing, invalid or unresolved data on the dates specified in § 490.317(b) for Interstate System and § 490.109(d)(2) and (d)(4) for non-Interstate NHS, if a reported section does not meet any one of the data requirements specified in §§ 490.309 and 490.311(c) or that reported section does not provide sufficient data to determine its Overall Condition specified in paragraphs (c) through (f) of this section:

(i) Total mainline lane-miles of missing, invalid, or unresolved sections for Interstate System and non-Interstate NHS shall be limited to no more than 5 percent of the total lane miles less the sections excluded in § 490.313(f)(1). For each pavement section without collected its condition metrics and inventory data, State DOTs shall note in the HPMS submittal with a specific code identified in the HPMS Field Manual (incorporated by reference, see § 490.111) noting the reason it was not collected.

(ii) Calculation of overall pavement conditions in any State meeting the requirements of § 490.309(b) shall be based only on sections containing data reported in the HPMS Submittal as of the submission dates required in § 490.311(c)(4) and (5). State DOTs not meeting the requirements of § 490.309(b) will be considered as not in compliance with § 420.105(b) requiring State DOTs to submit data to the HPMS and not in compliance with § 490.107 requiring reporting on performance targets. Failure to report data meeting the requirements of § 490.309(b) by the submission dates for the Interstate System will be considered as not meeting the minimum requirements for pavement conditions on the Interstate System and that State DOT is subject to the penalties in § 490.315.

(2) Not later than 1 year after the effective date of this regulation, State DOTs shall submit their Data Quality Management Program to FHWA for approval. Once FHWA approves a State DOT's Data Quality Management Program, the State DOT shall use that Program to collect and report data required by §§ 490.309 to 490.311. State DOTs also shall submit any proposed significant change to the Data Quality Management Program to FHWA for approval prior to implementing the change.

(c) State DOTs shall report the four pavement metrics listed in § 490.309(a) as calculated following the requirements in paragraphs (a) and (b) of this section in accordance with the following relevant HPMS requirements:

(1) Pavement condition metrics shall be reported to the HPMS in uniform section lengths of 0.1 mile (528 feet); shorter sections are permitted only at the beginning of a route, the end of a route, at bridges, or other locations where a section length of 0.1 mile is not achievable; and the maximum length of sections shall not exceed 0.11 mile (580.8 feet)

(2) Each measured section shall have a single value for each of the relevant condition metrics. Sections where condition is estimated from PSR will have one value for the overall condition.

(3) The time and location reference shall be reported for each section as follows:

(i) The State__Code, Route__ID, Begin__Point, and End__Point shall be reported as specified in the HPMS field manual (incorporated by reference, see § 490.111) for each of the four condition metrics.

(ii) The Year__Record shall be reported as the four digit year for which the data represents for each of the four condition metrics; and

(iii) The Value__Date shall be reported as the month and year of data collection for each of the four condition metrics.

(4) Sections for the four condition metrics shall be reported to the HPMS for the Interstate System by April 15 of each year for the data collected during the previous calendar year.

(5) Sections for the four condition metrics shall be reported to the HPMS for the non-Interstate NHS by June 15 of each year for the data collected during the previous calendar year(s).

(ii) Calculation of overall pavement conditions in any State meeting the requirements of § 490.309(b) shall be based only on sections containing data reported in the HPMS Submittal as of the submission dates required in § 490.311(c)(4) and (5). State DOTs not meeting the requirements of § 490.309(b) will be considered as not in compliance with § 420.105(b) requiring State DOTs to submit data to the HPMS and not in compliance with § 490.107 requiring reporting on performance targets. Failure to report data meeting the requirements of § 490.309(b) by the submission dates for the Interstate System will be considered as not meeting the minimum requirements for pavement conditions on the Interstate System and that State DOT is subject to the penalties in § 490.315.

(iii) For highways with a posted speed limit less than 40 miles per hour, an alternate method for estimation of IRI is permitted as described in § 490.309(b)(1)(iv) or § 490.309(b)(2)(iii) may be used in lieu of measuring IRI, cracking, rutting and faulting.

(iii) For highways with a posted speed limit less than 40 miles per hour, an alternate method for estimation of IRI is permitted as described in § 490.309(b)(1)(iv) or § 490.309(b)(2)(iii) may be used in lieu of measuring IRI, cracking, rutting and faulting.

(iii) Shall not be estimated from a PSR or other observation-based method except where permitted in § 490.309(b)(3)(iii).
