燃烧法测定沥青混合料中沥青含量应用的探讨

Research on Application of Burning Method to Determine Asphalt Content of Bituminous Mixtures

燃烧法是一种快速和准确测定沥青含量的方法。影响沥青含量测定结果的因素主要为集料的烧失量 ,这是一个已定系统误差 ,可以用设定修正系数的方法加以消除 ,使测定结果接近约定真值 ,从而达到精确测定沥青含量的目的。

The burning method is a quick and accurate way to determine asphalt content of bituminous mixtures. The mass loss of aggregate after burning is a main factor which affects the results of asphalt content determination.It is a fixed system error.It can be eliminated by using given amendatory coefficientto make the results of determination approach truth values,and the goal to determine accurately asphalt content is achieved.
