Assessment of behavior of warm mix asphalts in the low-temperature range

Popis výsledku v původním jazyce

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 binders 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 binders. Several additives have been usedand experimentally tested with respect to their performance characteristics of bituminous binders and asphalt mixes. The influence of the additives on behaviour of the binder and asphalt mix in low-temperature range (0 to -5°C) has been assessed by different test methods ? flexural strength on beam specimens and resistance to crack propagation on semicylidrical specimens. For bituminous binders performance has been assessed by bending stiffness using bending beam rheometer. Gained resul
