Abstract

The interaction parameter K.Ziegel-B was used as an evaluation index to characterize asphalt-aggregate filler interactions. In this study of asphalt-aggregate filler interactions, the rheological properties of asphalt mastics using two kinds of asphalts and four kinds of aggregate powder under different filler concentrations were measured by a dynamic shear rheometer, the internal influence factors of asphalt-aggregate filler interactions were analyzed, and the significance of influence factors were sorted by using the variance analysis method. The research shows that filler concentration, asphalt components, silica content, and particle size of aggregate powder all have a certain regularity effect on asphalt-aggregate filler interactions. The variance analysis method reveals the contribution order of various influence factors on interactions, the contribution order from high to low are colloid and asphaltene, particle size of aggregate, silica content and filler concentration.
