通过对壳牌 SBS改性沥青 (Caribit)、壳牌宽域沥青 (Multiphalte)和壳牌重交 AH - 70等 3种沥青进行原样及 RTFOT后的 DSR试验 ,以及 3种沥青拌制的 AC- 13型沥青混合料小梁弯曲疲劳试验 (应力控制模式 ) ,探讨了 3种沥青在疲劳性能方面的差异 ;验证了 DSR试验结果与沥青混合料小梁弯曲疲劳试验 (应力控制模式 )结果的相关性
Through the DSR tests of three kinds of asphalt, including Shell SBS modified asphalt (Caribit), Shell Shell asphalt (Multiphalte) and Shell AH - 70, and DSR test after RTFOT, three types of asphalt blended with AC - 13 asphalt The bending fatigue test (stress control mode) of the mixture trabeculae, the differences in the fatigue properties of the three kinds of asphalt are discussed, and the correlation between the DSR test results and the bending fatigue test (stress control mode) of the asphalt mixture is validated
