Title:

MDOT SHA Pavement Condition (NHS) [Maryland]

Description:

Esri ArcGIS Online (AGOL) Hosted Feature Layer which provides access to the MDOT SHA Pavement Condition NHS data product.MDOT SHA Pavement Condition (NHS) data consists of linear geometric features which represent roadway pavement conditions along the National Highway System (NHS) throughout the State of Maryland. This data product includes the national transportation performance measure infrastructure conditions, specifically the Good, Fair, & Poor condition ratings. These condition ratings, depending on surface type, are based on roughness, cracking, rutting & faulting.MDOT SHA Pavement Condition NHS data is owned & maintained by the MDOT SHA Office of Materials Technology (OMT). This data product is consistently updated on an annual basis for the prior year. This data product is for the year 2021. Though this data product as a whole is owned & maintained by MDOT SHA, the pavement conditions along roadways maintained by other Federal, State, County, and local government agencies are included within this data product. Roadway maintenance responsibility information can be further understood through the attribute values related to each linear segment.MDOT SHA Pavement Condition (NHS) data includes performance measures for pavements that are based on three condition ratings of Good, Fair, &Poor calculated for each pavement section, as described in Detailed in "National Performance Management Measures for Assessing Pavement Condition," 23 CFR 490 Subpart C (Code of Federal Regulations).The includedCondition Ratings are determined or calculated as follows:International Roughness Index (IRI) Condition Rating shall be determined / calculated for all pavement types using the following criteria. If an IRI value of a pavement section is: -- Less than 95, the IRI rating for the pavement section is Good;- Between 95 and 170, the IRI rating for the pavement section is Fair; and- Greater than 170, the IRI rating for the pavement section is Poor.Cracking Condition Ratingshall be determined/calculated using the following criteria:(i) For asphalt pavement sections -- If the Cracking_Percent value of a section is less than 5 percent, the cracking rating for the pavement section is Good;- 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- 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 -- If the Cracking_Percent value of a section is less than 5 percent, the cracking rating for the pavement section is Good;- 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- If the Cracking_Percent value of a section is greater than 15 percent the cracking rating for the pavement section is Poor.(iii) For CRCP sections:- If the Cracking_Percent value of a section is less than 5 percent, the cracking rating for the pavement section is Good;- 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- If the Cracking_Percent value of a section is greater than 10 percent, the cracking rating for the pavement section is Poor.Rutting or Faulting Condition Rating shall be determined / calculated using the following criteria.(i) For asphalt pavement:- If the rutting value of a section is less than 0.20 inches, the rutting rating for the pavement section is Good;- 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- If the rutting value of a section in is greater than 0.40 inches, the rutting rating for the pavement section is Poor.(ii) For jointed concrete pavement:- If the faulting value of a section is less than 0.10 inches, the faulting rating for the pavement section is Good;- 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 If the faulting value of a section is greater than 0.15 inches, the faulting rating for the pavement section is Poor.- The overall pavement condition to calculate good/poor metrics combines consideration of IRI, cracking and rutting/faulting, depending on surface type.Overall Pavement Condition Ratingis determined or calculated as follows:Good- For asphalt and jointed concrete pavements if all three metrics (IRI, cracking, and rutting/faulting) are good.- For continuous concrete pavements if both IRI and cracking are good.Poor- For asphalt and jointed concrete pavements if at least two metrics (IRI, cracking, and rutting/faulting) are poor.- For continuous concrete pavements if both IRI and cracking are poor.Fair- For all other combinationsFor additional information, contact the MDOT SHA OIT Enterprise Information Services:Email:GIS@mdot.maryland.gov
