本文利用废旧胶粉、SBS两种改性剂,70#基质沥青为初始沥青,进行改性沥青的制备,基于基础性能指标与流变性能指标对比研究不同掺量胶粉对基质及SBS改性沥青性能的影响。试验结果表明:随着胶粉掺量的增加,沥青的高温稳定性、低...展开更多 本文利用废旧胶粉、SBS两种改性剂,70#基质沥青为初始沥青,进行改性沥青的制备,基于基础性能指标与流变性能指标对比研究不同掺量胶粉对基质及SBS改性沥青性能的影响。试验结果表明:随着胶粉掺量的增加,沥青的高温稳定性、低温抗裂性能逐渐提升,但是对延度指标产生不利影响。胶粉对SBS改性沥青的软化点、延度的提升具有显著的作用,但会导致改性沥青的针入度降低...

In this paper,modified asphalt was prepared using the initial asphalt as the 70#base asphalt,and waste crumb rubber powder(CR)and Styrene-butadiene-styrene(SBS)as the modifier.The effects of different proportion of waste crumb rubber powder on properties of base asphalt...MORE In this paper,modified asphalt was prepared using the initial asphalt as the 70#base asphalt,and waste crumb rubber powder(CR)and Styrene-butadiene-styrene(SBS)as the modifier.The effects of different proportion of waste crumb rubber powder on properties of base asphalt and SBS modified asphalt were studied based on the ...
