摘要
通过纳米粉粒(A、S)、燕山4303SBS和克拉玛依70#沥青相组合的14种沥青室内试验研究(针入度、软化点、延度、RTFOT和BBR试验等),分析了纳米种类和剂量对基质沥青和改性沥青性能的影响,讨论了纳米改性沥青的老化特性,初步结果表明纳米改性沥青是可行的。
Through the lab tests （ Penetration, R＆B softening point, ductility, RTFOT and BBR tests） of 14 type of asphalt,which were combined with nano-particles A and S, Yanshan 4303 SBS and a base asphalt KLMY AH-70^#,the performances were analyzed about the base and modified asphalts influenced by nanoparticle types and dosage,and the influence of aging stability was also discussed. The results manifested that the nano-particles modified asphalt was practicable, but there is a long way to go.
