改善沥青使用性能添加剂的应用研究

APPLICATION RESEARCH OF ADDITIVES FOR IMPROVING ROAD ASPHALT PROPERTY

针对交通部2004年修订的《公路沥青路面施工技术规范》JTGF40—2004对沥青性质的要求,开发了两种沥青添加剂FR1和FN1,将二者添加到多种基础沥青中,进行了实验室评价、中型试验和工业化试验,结果表明,这两种添加剂可改善沥青性质,使产品指标符合上述规范中几种主要牌号的A级沥青技术要求。

Revised specifications for paving asphalt were announced by the Ministry of Communications of China as JTG F40-2004 in 2004. Two asphalt additives,FR1 and FN1 ,were developed to improve the asphalt properties for meeting the requirements of JTG F40-2004. Test results of laboratory,pilot plant and commercial unit showed that adding proper amount of FR1 and/or FN1 into various base asphalts could improve the asphalt performance, such as penetration index, ductility and viscosity; as a result,the product qualities met the revised requirements of several grade A products .
