摘要
由于胶粉含量大,橡胶沥青的稳定性和抗老化性能不足。引入橡胶沥青连接剂(TOR),通过TOR中的双键结构,增强橡胶沥青中废旧胶粉之间的交联,进而提升橡胶沥青的抗老化性能。结果显示,相比于普通橡胶沥青,TOR改性后橡胶沥青的抗老化性能得到了显著提升。
The high rubber powder content causes insufficient stability and anti-aging properties of the rubber asphalt.By introducing the trans-polyoctenamer rubber(TOR),its double bond structure ould strengthen the crosslinking between waste rubber powder in the rubber asphalt,to further improve the anti-aging properties.The results indicated that compared with ordinary rubber asphalt,the anti-aging properties of the TOR-modified rubber asphalt had significantly improved.
