本文采用三种不同的天然沥青（特立尼达湖沥青、伊朗沥青和美国沥青）和苯乙烯-丁二烯-苯乙烯（SBS）作为改性剂对沥青进行改性。结合料试验结果表明，在PG 58-34纯沥青中加入10.0%的美国硬沥青（MB10%AG）、9.5%的伊朗硬沥青（MB9.5%IG）、60%的特立尼达湖沥青（TLA）（MB60%TLA）和3.8%的SBS（MB3.8%SBS）可达到预期的性能水平（PG 70-34）。混合料试验表明，用MB60%TLA配制的混合料具有最高的刚度、稳定性、抗拉强度、抗疲劳和永久变形能力。另一方面，观察到用MB9.5%IG和MB3.8%SBS制备的混合物具有最高的抗水分诱导的损伤性。(C)2013爱思唯尔有限公司保留所有权利。
In this study, three different natural asphalts (Trinidad Lake Asphalt, Iranian gilsonite and American gilsonite) and styrene-butadiene-styrene (SBS) were used as additive in bitumen modification. Results of binder tests showed that addition of 10.0% American gilsonite (MB10%AG), 9.5% Iranian gilsonite (MB9.5%IG), 60% Trinidad Lake Asphalt (TLA) (MB60%TLA)and 3.8% SBS (MB3.8%SBS) to pure bitumen (PG 58-34) achieved the desired performance level (PG 70-34). Experiments conducted on mixtures showed that mixtures prepared with MB60%TLA had the highest stiffness, stability, tensile strength and resistance to fatigue and permanent deformation. On the other hand, mixtures prepared with MB9.5%IG and MB3.8%SBS were observed to have highest resistance to moisture induced damage. (C) 2013 Elsevier Ltd. All rights reserved.
