§ 490.301 - Purpose.

The purpose of this subpart is to implement the following statutory requirements of 23 U.S.C. 150(c)(3) to:

(a) Establish measures for State DOTs and MPOs to assess the condition of pavements on the Interstate System;

(b) Establish measures for State DOTs and MPOs to assess the condition of pavements on the NHS (excluding the Interstate);

(c) Establish minimum levels for pavement condition on the Interstate System, only for purposes of carrying out 23 U.S.C. 119(f)(1);

(d) Establish data elements that are necessary to collect and maintain standardized data to carry out a performance-based approach; and

(e) Consider regional differences in establishing the minimum levels for pavement conditions on the Interstate System.

§ 490.303 - Applicability.

The performance measures in this subpart are applicable to the mainline highways on the Interstate System and on the non-Interstate NHS.

§ 490.305 - Definitions.

The following definitions are only applicable to this subpart, unless otherwise provided:

Asphalt pavements means pavements where the top-most surface is constructed with asphalt materials. These pavements are coded in the HPMS as having any one of the following Surface Types:

Code Surface__type
2Bituminous.
6Asphalt-Concrete (AC) Overlay over Existing AC Pavement.
7AC Overlay over Existing Jointed Concrete Pavement.
8AC (Bituminous Overlay over Existing CRCP).

Continuously Reinforced Concrete Pavements (CRCP) means pavements where the top-most surface is constructed of reinforced Portland cement concrete with no joints. These pavements are coded in the HPMS as having the following Surface Type:

Code Surface__type
5CRCP—Continuously Reinforced Concrete Pavement.

Cracking means an unintentional break in the continuous surface of a pavement.

Cracking Percent means the percentage of pavement surface exhibiting cracking as follows:

(1) For asphalt pavements, Cracking Percent is the percentage of the area of the pavement section, exhibiting visible cracking.

(2) For jointed concrete pavements, Cracking Percent is the percentage of concrete slabs exhibiting cracking.

(3) For CRCP, the Cracking Percent is the percentage of pavement surface with longitudinal cracking and/or punchouts, spalling or other visible defects.

Faulting means a vertical misalignment of pavement joints in Portland Cement Concrete Pavements.

International Roughness Index (IRI) means a statistic used to estimate the amount of roughness in a measured longitudinal profile. The IRI is computed from a single longitudinal profile using a quarter-car simulation, as described in the report: “On the Calculation of IRI from Longitudinal Road Profile” (Sayers, M.W., Transportation Research Board 1501, Transportation Research Board, Washington, DC 1995).

Jointed concrete pavements means pavements where the top-most surface is constructed of Portland cement concrete with joints. It may be constructed of either reinforced or unreinforced (plain) concrete. It is coded in the HPMS as having any one of the following Surface Types:

Code Surface__type
3Jointed Plain Concrete Pavement (includes whitetopping).
4Jointed Reinforced Concrete Pavement (includes whitetopping).
9Unbonded Jointed Concrete Overlay on PCC Pavement.
10Bonded PCC Overlay on PCC Pavement.

Pavement means any hard surfaced travel lanes of any highway.

Pavement section means a nominally 0.1 mile-long reported segment that defines the limits of pavement condition metrics required by FHWA.

Present Serviceability Rating (PSR) means an observation based system used to rate pavements.

Punchout means a distress specific to CRCP described as the area between two closely spaced transverse cracks and between a short longitudinal crack and the edge of the pavement (or a longitudinal joint) that is breaking up, spalling, or faulting.

Rutting means longitudinal surface depressions in the pavement derived from measurements of a profile transverse to the path of travel on a highway lane. It may have associated transverse displacement.

Sampling as applied to pavements, means measuring pavement conditions on a short section of pavement as a statistical representation for the entire section. Sampling is not to be used to measure or rate NHS pavement conditions.

§ 490.307 - 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.

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

(iii) Greater than 170, the IRI rating for the pavement section is Poor.

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

(i) For asphalt pavement sections—

(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.

(ii) For jointed concrete pavement sections—

(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.

(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.

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.

(c) The Overall condition for asphalt and jointed concrete pavement sections shall be determined based on the ratings for IRI, Cracking__Percent, rutting and faulting, as described in paragraphs (b)(1), (b)(2), (b)(3) and (b)(4) of this section, respectively, for each section as follows:

(2) A pavement section shall be rated an overall condition of Poor if two or more of the three conditions are exhibiting Poor ratings (at least two ratings of Poor for IRI, Cracking__Percent, and rutting or faulting).

(3) A pavement section shall be rated an overall condition of Fair if it does not meet the criteria in paragraphs (c)(1) or (c)(2) of this section.

(4) For sections on roadways where the posted speed limit is less than 40 MPH and where the State DOT has reported PSR in lieu of the IRI, Cracking__Percent, rutting, and faulting metrics the PSR condition level shall be determined using the following criteria:

(i) If the PSR of a section is equal to or greater than 4.0 the PSR rating for the pavement section is Good;

(ii) If the PSR of a section is less than 4.0 and greater than 2.0 the PSR rating for the pavement section is Fair; and

(d) The Overall condition for CRCP sections shall be determined based on two ratings of IRI and Cracking__Percent, as described in paragraphs (b)(1) and (b)(2) of this section or based on PSR where appropriate as described in paragraph (c)(4) of this section, respectively, for each section as follows:

(1) A pavement section shall be rated an overall condition of Good only if the section is exhibiting Good ratings for both conditions (IRI and Cracking__Percent);

(2) A pavement section shall be rated an overall condition of Poor if it exhibits Poor ratings for both conditions (IRI and Cracking__Percent);

(3) A pavement section shall be rated an overall condition of Fair if it does not meet the criteria in paragraphs (d)(1) or (d)(2) of this section.
