摘要
近年来国家基础建设蓬勃发展,以高铁、高速公路为代表的运输线路增幅较往年有质的飞跃,而改性沥青在其中发挥着至关重要的作用。如何将改性沥青效能发挥至最优,稳定剂的使用及用量非常关键,因此本论文旨在探讨改性沥青中三种稳定剂的最佳添加量,并横向对比三种稳定剂对改性沥青针入度、软化点、延度、TFOT延度、离析的影响。结果证明,稳定剂Y与Z都能使改性沥青各项指标达到合格,稳定剂S的TFOT延度相对较差。
In recent years,with the vigorous development of national infrastructure,the growth of transportation lines such as high-speed railway and highway has made a qualitative leap over previous years,in which modified asphalt plays a vital role.In order to optimize the performance of modified asphalt,the type and dosage of stabilizer is very important.Therefore,the best dosage of three stabilizers in modified asphalt was explored,and the effects of three stabilizers on penetration,softening point,ductility,TFOT ductility and segregation of modified asphalt were compared.The results showed that both stabilizers Y and Z could meet the requirements of modified asphalt,and the TFOT ductility of stabilizer S was relatively poor.
