Validation of the Polygon-Of-Voids Tool for Asphalt Mixtures with RAP

Durability of an asphalt mixture is directly related to the optimum asphalt binder content, which guarantees coverage of the aggregate particles and suitable volumetric properties to ensure a good performance in service, producing an asphalt mixture that is less susceptible to aging and moisture dam...
