Preliminary Evaluation of Field Aging Characteristic of Warm Mix Asphalt
This study is aimed at evaluating the rate of long-term aging of WMA compared to conventional hot-mix-asphalt (HMA). A test section with recorded traffic and weather information was designated in this study. Field cores of two WMAs and one conventional HMA were taken from the field periodically. Both mix and binder properties of retrieved were measured in the laboratory. The resilient modulus and indirect tensile test were performed to characterize mixture properties. The rheological properties of extracted binder were measured by the dynamic shear rheometer (DSR) in order to obtain the complex shear modulus (G*) as well as the phase angle (δ) of binder with and without the WMA additives.
