20-1 Evaluation of Stripping Potential Tests for Bituminous Concrete

Project Dates: Jul 31, 2021 - Mar 31, 2022
Project Description:

One of the prevalent failure modes of Hot Mix Asphalt (HMA) is disintegration of aggregates over times due to loss of adhesion/binding between asphalt binder and aggregate. This phenomenon is referred to as "stripping" and in broader terms  addresses moisture-induced damage in HMA. The moisture damage starts simply by presence of water and can lead to acceleration of other pavement distress modes such as permanent deformation, fatigue and thermal cracking in the asphalt concrete. This project will perform laboratory tests on mix designs with and without anti-stripping additives to determine any required updated to the current VTrans testing procedure.
