Effect of Waterborne Emulsion on Performance of Polymer-modified Fog Seal Materials

Abstract:

The traditional indexes test， multiple stress creep and recovery （MSCR） test， amplitude sweep and frequency sweep test were conducted to study the rejuvenation effect of fog seal material on aging asphalt. Then， the freeze-thaw splitting test and Cantanbro stripping test of Marshall specimens soaked in fog seal materials were also conducted to explore the effect of fog seal materials on the durability of asphalt mixture， respectively. It is shown that the waterborne acrylate and waterborne polyurethane play a synergistic enhanced effect and improve the elastic properties of asphalt. The fog seal materials with carbamate and carboxyl polar groups enhance water stability and anti-loosening performance of asphalt mixture significantly. According to the significance testing and grey relational analysis， the regeneration indexes of the fog seal materials present a strong consistency.
