This document is a technical summary of the unpublished Federal Highway Administration (FHWA) report The Universal Simple Aging Test (USAT) and Low Temperature Performance Grading Using Small Plate Dynamic Shear Rheometry: An Alternative to Standard RTFO, PAV, and BBR for HMA and WMA. This TechBrief provides an overview of the Universal Simple Aging Test (USAT), which is an alternative to use of standard rolling thin-film oven (RTFO) and pressure aging vessel (PAV) testing for asphalt binders.
