摘　　要：基于水煮法,采用剥落率对沥青/集料粘附性进行定量评价。通过冻融劈裂试验、浸水马歇尔试验及汉堡车辙试验等,对热拌再生橡胶沥青混合料水稳定性进行了系统的试验研究。结果表明:剥落率R能有效评价沥青/集料粘附性;沥青再生剂能恢复橡胶沥青混合料的水稳定性;和浸水马歇尔试验相比,冻融劈裂试验对SMA-13粗级配的水损害更为严重;在汉堡车辙试验中,高温稳定性和水稳定性呈相反关系。Ratio of asphalt stripping was presented to quantificationally evaluate the adhesivity of asphalt and makings based on boiling water method in this study. The freeze-thaw splitting test, immersion Marshall test and Hamburg rut test were operated to estimate the water stability of hot mix reclaimed rubber asphalt mixture. It indicated that it is effec- tive to evaluate the adhesivity of asphalt and makings by asphalt stripping ratio. The water stability of reclaimed rubber asphalt mixture like that of before ageing. Compared with immersion Marshall test, freeze-thaw splitting test has more damages in coarse grading SMA-13. It has an inverse relationship between high temperature stability and water stability during Hamburg rut test.
