Selected performance-based characteristics of viscosity improved bituminous binders

Warm mix asphalts present a trend of last decade with a focus on reduced energy demand and released emissions and bituminous vapours. One of the used techniques is application of suitable organic or chemical additives or surfactants which are used as dopes for bituminous hinders or are added during mix production directly to the asphalt production. Research done on the Czech Technical University focused on the use of such additives in combination with bituminous hinders. Several additives have been used together with 50/70 and 70/100 bitumen and experimentally tested with respect to their performance characteristics. The influence on viscosity (dynamic viscosity), deformation behavior (complex shear modulus, master curves) and performance in low-temperature range (bending stiffness by Bending Beam Rheometer) has been assessed. Gained results and influence of selected and tested additives is presented in this paper.
