Abstract: First developed a contrastive study on Troxler furnace and centrifugal separation method，then introduced the correl ative experiments contents and conclusion of asphalt content testing with the Troxler furnace organized by National Center for Asphalt Technology(NCAT)．Two experiments showed that Troxler furnace could be used tO exactly measure asphalt content of HMA and didn’t alter aggregate gradation remarkably．

Key words: asphalt content, Troxler furnace, asphalt mixture

摘要： 首先通过室内试验对Troxler燃烧炉与离心分离法测定沥青含量做了对比研究；然后介绍了美国国家沥青技术 中心(NCAT)组织的用Troxler燃烧炉测定沥青含量比对试验的试验内容和结论．两个试验都表明Tmxler燃烧炉法 能比较准确地确定沥青混合料的沥青含量，而且对石料的级配组成影响不大．
