硅藻土在改性沥青中的应用及产品性能研究

摘要

The raw material, quality requirement, preparation methods, modification effect and product performance of diatomite used for pitch modification were studied. The results showed that the modification effect of diatomite which dominant species was melosira was better than others. And the pyro - purification of diatomite had the advantage over the hydro - purification.%对改性沥青所用的硅藻土原料、质量要求、制备方法、改性效果和产品性能进行了系统而全面地研究,结果表明,直链藻为优势种的硅藻土改性效果好于其它硅藻土；硅藻土“火法”提纯改性效果略优于“水法”.
