摘要
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 )
According to the DSR test result of original asphalt and the bitumen after RTFOT among Shell SBS modified bitumen (caribit),Shell Mutiphalte and Shell heavy-traffic asphalt(AH-70) and the test of crooked fatigue(stress controlling mode) by the asphalt mixture consist of AC-13 and the three types bitumen above respectively,the difference of the three types bitumen in the aspect of fatigue at the same time are studied,the relation between the test result of the asphalt DSR and crooked fatigue (stress controlling mode) is validated.
