Use of Adhesion Promoters in Asphalt Mixtures

Popis výsledku v původním jazyce

The purpose of asphalt as a significant binder in road constructions is to permanently bind aggregates of different compositions and grain sizes. The asphalt binder itself does not have suitable adhesiveness, so after a period of time, bare grains can appear. This results in a gradual separation of the grains from an asphalt layer and the presence of potholes in a pavement. Adhesion promoters or adhesive agents are important and proven promoters in practice. They are substances mainly based of fatty acids of polyamides which should increase the reliability of the asphalt&apos;s adhesion to the aggregates, thus increasing the lifetime period of the asphalt mixture as well as its resistance to mechanical strain. The amount of a promoter or agent added to the asphalt mixture is negligible, and constitutes about 0.3% of the asphalt&apos;s weight. Nevertheless, even this quantity significantly increases the adhesive qualities of an asphalt binder. The article was created in coopertation with the Slovak University of Technology, in Bratislava, Slovakia, and focuses on proving the new AD2 adhesive additive and compares it with Addibit and Wetfix BE promoters used on aggregates from the Skuteč - Litická and Bystřec quarries.
