Abstract The flow curves are plotted and analyzed for bitumen composites modified with tire rubber vulcanizates obtained via high-temperature shear-induced grinding and with butadiene styrene thermoelastoplastics of domestic and foreign manufacture. The efficiency of ground vulcanizates and thermoelastoplastics manifests itself at their various ratios in a bitumen/modifier system, which is due to the different mechanisms of their modifying effect. Two ranges in the flow curves of modified bitumen composites have been distinguished that are associated with peculiar regularities of the structural formation at various bitumen/modifier ratios and the modifier nature. Thus, the modifier content leading to the appearance of two pronounced ranges in the viscosity curves can be considered as an efficient concentration serving as an indicator of the beginning of the modifying effect of thermoelastoplastics and ground vulcanizates.

改性沥青复合材料流动曲线分析

摘要 绘制并分析了轮胎橡胶硫化胶经高温剪切诱导研磨和国内外生产的丁苯苯乙烯热塑性弹性体改性沥青复合材料的流动曲线。研磨硫化橡胶和热弹塑性材料的效率在沥青/改性剂体系中以不同的比例表现出来，这是由于它们改性作用的不同机制。改性沥青复合材料的流动曲线中的两个范围已被区分，它们与在各种沥青/改性剂比率和改性剂性质下结构形成的特殊规律有关。因此，
