摘要
考察了改性剂(LDPE、SBS)对改性沥青的改性效果的影响,包括改性剂(LDPE、SBS)的添加量对改性沥青的针入度、软化点、延伸度的影响,以及改性剂(SBS)的结构对改性沥青的针入度、软化点、延伸度的影响。相容性是彩色改性沥青混合料技术关键,研究了改性剂(LDPE、SBS)与基础油的相容性对改性沥青改性效果的影响,并制备了最佳条件的彩色改性沥青试样。
The influence of modifier(LDPE,SBS)on the modification effect of modified asphalt was investigated,including the influence of dosage of modifier(LDPE,SBS)on the degree of penetration,softening point and elongation of modified asphalt,and the influence of structure of modifier(SBS)on the degree of penetration,softening point and elongation of modified asphalt.Compatibility is the key technology of color modified asphalt mixture.The influence of compatibility between LDPE,SBS and base oil on modification effect of modified asphalt was studied.Qualified color asphalt can obtained at last.
