TxDOT Roadbed Surface

The Roadbed Surface describes the type of pavement on the surface of the roadway. Surface Type (i.e. Roadbed Surface) is a required asset for reporting to FHWA as part of the HPMS submittal. Principal factors in considering the selection of surface types are traffic, soil characteristics, weather, construction considerations, recycling opportunities, and cost comparison. See TxDOT's Pavement Manual for more information.
