为了合理地评价抗剥落剂对含盐高湿环境下沥青混合料水稳定性的影响，文章以抗剥落剂 PA-1、A M R和T J-066为研究对象，通过沥青与集料的黏附性试验确定抗剥落剂的最佳掺量，在不同温度下对掺有抗剥落剂的沥青混合料进行浸水汉堡车辙试验，并讨论了浸水汉堡车辙试验的试验条件和评价指标。结果表明：在含盐高湿环境中抗剥落剂 P、A、T 的最佳掺量略大于淡水环境，分别为沥青用量的0.4％、0.5％和0.5％；采用50℃时浸水汉堡车辙试验可以很好地评价不同抗剥落剂对沥青混合料水稳定性的影响。针对浸水汉堡车辙试验评价指标的不足，提出车辙深度变化率指标；掺有抗剥落剂A的沥青混合料车辙深度变化率最小，剥落次数最大，建议含盐高湿地区采用抗剥落剂A来提高沥青路面的水稳定性。
為瞭閤理地評價抗剝落劑對含鹽高濕環境下瀝青混閤料水穩定性的影響，文章以抗剝落劑 PA-1、A M R和T J-066為研究對象，通過瀝青與集料的黏附性試驗確定抗剝落劑的最佳摻量，在不同溫度下對摻有抗剝落劑的瀝青混閤料進行浸水漢堡車轍試驗，併討論瞭浸水漢堡車轍試驗的試驗條件和評價指標。結果錶明：在含鹽高濕環境中抗剝落劑 P、A、T 的最佳摻量略大于淡水環境，分彆為瀝青用量的0.4％、0.5％和0.5％；採用50℃時浸水漢堡車轍試驗可以很好地評價不同抗剝落劑對瀝青混閤料水穩定性的影響。針對浸水漢堡車轍試驗評價指標的不足，提齣車轍深度變化率指標；摻有抗剝落劑A的瀝青混閤料車轍深度變化率最小，剝落次數最大，建議含鹽高濕地區採用抗剝落劑A來提高瀝青路麵的水穩定性。

In order to evaluate the influence of anti-stripping agents on water stability of asphalt mix-ture in salty and humid environment reasonably ,anti-stripping agent PA-1(P) ,AMR(A) and TJ-066 (T) were selected ,and the optimum mixing amount of anti-stripping agents were determined by adhe-sion test of asphalt and aggregate .The Hamburg wheel tracking test in water at different tempera-tures on asphalt mixtures mixed with anti-stripping agents was carried out ,and the test condition and evaluation index were also discussed .The results show that the optimum mixing amount of anti-strip-ping agent P ,A or T in salty and humid environment are slightly larger than in conventional environ-ment ,the optimum mixing amount of anti-stripping agent P ,A and T are 0.4% ,0.5% and 0.5% of asphalt content respectively .The Hamburg wheel tracking test in water at 50 ℃ is a good way to e-valuate the influence of different anti-stripping agents on water stability of asphalt mixture .The index of rutting depth rate is put forward in view of the deficiency of the evaluation index of the Hamburg wheel tracking test in water .The rutting depth rate of asphalt mixture mixed with anti-stripping a-gent A is the smallest ,and stripping number is the biggest .Anti-stripping agent A is recommended to improve the water stability of asphalt mixture in salty and humid area .
