摘要： 通过对SMA改性沥青混合料抽提试验结果的分析发现,抽提后人工挑出的纤维包裹了部分细矿料,从而引 起油石比和纤维质量的偏差;对此偏差进行了试验分析并提出改进方案;同时对SMA改性沥青混合料油石比计算 做出了修正。

Abstract: Through analysis of the extracting test results of SMA modified asphalt mixture, it is discovered that the wooden fiber after the extraction selected out by manual work enwraps some fine aggregate, which leads to the quality deviation of asphah-aggregate ratio and wooden fiber. Aiming at this deviation, the test is carried out and some improvement projects are proposed. Finally, the calculation to asphalt-aggregate ratio of the SMA modified asphalt mixture is amended.

Key words: extraction method , Stone Matrix Asphalt（SMA） , wooden fiber , asphalt-aggregate ratio ;
