Impact of selected WMA additives on normal PMB used for a standardized SMA

Original language description

WMA techniques are well known for many years, even if still not increasingly popular in Europe. In the Czech Republic so far these techniques – mainly different types of wax based additives and surfactants – were used for asphalt concrete and usually in combination with a normal pen grade (70/100 or 50/70). As part of an ongoing research the focus was laid on SMA mixes which are as in any other country used mainly as a top wearing course for pavements with highest loadings and life-time expectations. Even if it is still allowed to use normal distilled bitumen, the best effect is achieved if PMBs are applied. For this reason a typical mix design for SMA11 mix was selected and more than 15 different binders have been used divided in three groups – two where effect of different WMA additives was analysed on PMB 25/55-55 of two selected origins and last group containing a more modified binder (not for WMA) and a 50/70 binder modified by PPA. As WMA additives different waxes have been used, selected surfactants and a nano-based additive. Firstly all bituminous binders were analysed by empirical tests, dynamic viscosity, MSCR and frequency sweep test. Then the mixes were prepared with a temperature reduced by 20-25°C in comparison to reference mix, For all mixes voids content, stiffness, ITSR, rutting and crack propagation was analysed and will be summarized in the paper.
