Original Kurzfassung:
Bitumen-free asphalt mixtures are a well-known substitute for classical asphalt pavements. It was shown that they improve the life-time and also reduce the environmental impact of asphalt mixtures. Moreover, polymer-based mixtures enable adjustable properties based on specific requirements. In a previous study the influence of three different mineral filler on the stiffness and the load-bearing capacity of bitumen free asphalt mixtures were investigated.
The objective of this study is to derive material parameters for modeling the viscoelasticity and derive structure-property-relationship to gain insights of the influence of silica dust (SD), silica sand (SS), and basalt sand (BS).
