摘要
探讨了不同掺量的有机添加剂Leadcap对沥青性能指标的影响,试验结果表明加入Leadcap添加剂后基质沥青针入度稍微下降,软化点变化不大,但10℃延度显著提高,同时leadcap能使沥青低温粘度增加,高温时粘度减小,并且出现使沥青粘度大幅度下降的温度区间。
The performance analysis of asphalt with Leadcap is discussed, The result showed that the penetration of asphalt with Leadcap decreased, softening point had no obvious change, but ductility at 10℃C increased. Also, the viscosity increased at low temperature and decreased at high temperature , and the viscosity decreased obviously at a certain temperature range.
