Ermittlung der dynamischen Werkstoffkonstanten von bituminös gebundenen Baustoffen

The evaluation of the dynamical properties of bituminous mixtures An experimental method for the evaluation of the dynamical properties of bituminous mixtures is presented. Because of their viscoelastic behaviour the design of a special testing device was necessary. In this paper the guiding ideas for this testing machine are developed. Moreover, some experimental results and experiences, which could be valuable for calculating the stresses in road constructions, are given.
