纳米添加剂量对沥青混合料性能的影响

Effects of Nano-Addition on the Performance of Asphalt Mixture

研究了不同剂量的纳米粉粒分别添加到基质沥青和沥青混合料中后对沥青混合料性能的影响.通过室内原样沥青常规试验和沥青混合料的马歇尔试验研究,分析了不同纳米剂量对沥青混合料马歇尔技术指标的影响曲线,得出纳米添加剂量为最佳沥青用量的5%左右时沥青混合料性能最优.

Different amount of nano-powders were added to the base asphalt and its mixture respectively to investigate the influence of the nano-additions on the performance of asphalt mixture. The influence of different nano-doses of asphalt mixture on the Marshall specifications was analyzed through conventional tests of original asphalt in laboratory and the Marshall test. The asphalt mixture exhibites best performance when the amount of nano-additives is about 5%.
