Name: Base_2024

Display Field:

Type: Feature Layer

Geometry Type: esriGeometryPolyline

Description:

Identifies the material type (e.g. asphalt, concrete) and thickness of the base layer that is between the subgrade (soil) and the bottom of the surface pavement. This layer is important for pavement analysis and modeling.

Reported Extent: All paved sample panel sections. Sample panel sections are any roadways, or parts of roadways, that were identified by the Federal Highway Administration (FHWA) as requiring additional data to be reported in the 2024 HPMS report. Values may be available for other roads but are not actively maintained.
