Abstract: With AC-16 salt SBS modified asphalt mixture for an object, relying specification water stability evaluation, based on existing research data, analyzing influence of different salinization matter, different salinization contents and soak time for water stability of the salt asphalt mixture. The results showed that two typical Salt was the impact of water stability of Asphalt, although the difference, but the difference is not great； different dosage effect water stability of the Salt asphalt mixture is particularly significant； the soaking time was affecting water stability of Salt asphalt mixture another major factor.
