Evaluation of Aging of Hot Mix Asphalt Using Wave ...

Abstract. A methodology for determining the degree of aging of hot-mix asphalt (HMA) is presented. The evaluation of aging involves relating the wave propagation velocities to the elastic modulus of the mixture, before and after aging. The nondestructive nature of the methodology and its high degree of repeatability make it attractive to ...
