During the use of asphalt pavement, the water in the pavement produced a freeze-thaw cycle due to the change of temperature, which caused a large number of early diseases on the pavement. In this paper, the water stability of the asphalt mixture of three kinds of asphalt were tested after multiple freeze-thaw cycles. The results show that under the same number of freeze-thaw cycles, the asphalt mixture’s cracking strength, freezing-thawing splitting test strength ratio (TSR), and water stability were, from large to small: SBS modified asphalt > asphalt with anti-stripping agent > base asphalt.
