Abstract:

The article presents test results of the correlation of zero shear viscosity (Șo) and the G*/sinį parameter with rutting parameters
WTSAIR and PRDAIR. The tests were conducted on asphalt concrete AC11S containing synthetic wax in the range 1.5% to 4.0%
with a step of 0.5%, compacted at 115°C to 145°C with a step of 10°C. Zero Shear Viscosity was determined using the
Cross/Sybilski rheological model. The results of WTSAIR and PRDAIR showed better agreement with the Șo parameter (R2> 95%)
than with the G*/sinį parameter, which reached the test convergence of R2
= 73%. The ZVS parameter exhibited a higher sensitivity
to rutting resistance and stiffness results of asphalt concrete. Moreover, the increase in the amount of synthetic wax F-T used
increased the rutting resistance of the asphalt mixture. Parameters ZSV and G*/sinį did not correlate. The ZSV parameter showed
higher sensitivity and correlation with the results obtained for the rutting resistance of asphalt concrete. Therefore, G*/sinį should
be used more carefully in the prediction of the resistance to rutting of asphalt mixtures with synthetic wax. The ZSV parameter
should be used as a major indicator characterizing the susceptibility of asphalt mixtures rutting. This is particularly warranted when
new asphalt mix modifiers are applied.
