Abstract:

Accurate determination of asphalt content is critical to ensuring the quality of asphalt mixes used in Wisconsin’s road projects. The two most-common methods for determining asphalt content are the American Association of State Highway and Transportation Officials (AASHTO) solvent extraction and ignition tests. These procedures are well established; however, their accuracies are sensitive to variations in materials and high recycled binder content mixes commonly used in Wisconsin. Therefore, an evaluation is needed to assess within-lab and between-lab testing variability. The main objectives of this research were to evaluate solvent extraction, ignition and asphalt analyzer test procedures; determine tolerances between methods; and modify WisDOT material and mix standards. The research team also evaluated the variability of the performance grade (PG) properties of extracted binder after recovery.
