Asphalt binder may travel through multiple blending terminals along the supply chain depending on the properties required for the final use. After blending, suppliers transfer binder to asphalt mix plants where it is stored on site for use in asphalt mix production.

A.3 ABQT Background In most states, inspectors periodically visit supplier and contractor sites to collect samples of binder for QC testing and acceptance testing. However, most states do not have sufficient testing capacity, which has two important effects.

The ANN model incorporates test data from known binders meeting the Superpave PGs and uses the deflection and recovery curve measured over the 90-second test period to predict the PG of the asphalt binder sample. Furthermore, the ABQT was tested to compare the percentage recovery of the sample to the percentage recovery of the Multi-Stress Creep-Recover (MSCR)
