Preparation of SBS Modified Emulsified Asphalt in High Cold Region
College of Civil Engineering, Nanjing Forestry University, Nanjing, Jiangsu 210037, China
A kind of SBS modified emulsified asphalt for highly cold area was studied by experiments. The research includes two aspects: the first is preparation of SBS modified asphalt. The influence of temperature, time, shear rate and development time on asphalt modification are determined, so as to determine the process of SBS modified asphalt. On this basis, the blending ratio of SBS modified emulsified asphalt was determined by experiments. The results show that the emulsified asphalt produced by the equipment is of good quality and good ductility.4%SBS latex content can make emulsified asphalt meet the standard requirements, but only 6%SBS latex content can obtain better road performance. Although the softening point of SBS modified emulsified asphalt prepared by this method is still low, it can meet the requirements of high cold area.
