Assessment of the adhesive capacity of asphalt binders in the aggregate-binder bonds by means of new methodology

The main goal of this study is to present a new methodology to characterize the adhesive capacity (cohesion and adhesion capacity) of asphalt binders by means of new mechanical parameters. This methodology is based on the Fenix test, a test recently developed in Spain. This method assesses the crack...
