Abstract: Bituminous binder in asphalt mixture is exposed to the influence of aging, which is intensified during mixing and paving, as high temperature strongly accelerates the aging of bituminous binders. The aging of the binder is generally divided into short-term and long-term aging. The work focuses on comparing the properties of bitumen binders that differ in penetration value and aging level. All binders in the study are divided into these aging categories, and their properties are compared with the properties of unaged binders. The comparison of properties is carried out using basic empirical tests (penetration and softening point) as well as rheological tests (complex shear modulus and phase angle).
Keywords: aged binders; Bitumen; complex shear modulus; dynamic shear rheometer; phase angle
