摘要
通过室内针入度、软化点、延度、RTFOT和BBR等试验,分析了纳米SiO2、纳米TiO2加入到基质沥青和SBS改性沥青中后,对沥青的针入度、软化点、延度、复数剪切模量、车辙因子及疲劳因子等性能的影响。初步结果表明,纳米改性沥青的方法是可行的,为改性沥青的发展提供一种新思路。
Analysis is made on influence of adding nano SiO2 and nano TiO2 into matrix asphalt and into SBS modified asphalt upon the performance of asphalt such as penetration,softening point,ductility,plural shear modulus,rut factor and fatigue factor through indoor experiment on penetration, softening point, ductility, RIFOT and BBR. The primary result shows that the method of nano modifing asphalt is feasible that offers a new thought for the development of modified asphalt.
