摘要
目前我国建筑沥青的质量还不能满足建筑业日益发展的需要。为了提高其质量，大量的研究工作和工业生产都说明，目前国内外主要从以下３个方面进行改进：在工艺上采用催化氧化法，选用合适的催化剂；原料组成采用２种或多种适当的原料进行调合；在原沥青的基础上掺配不同的添加剂。本文对国内这３方面的一些工作做了介绍。
The quality of current domestic building asphalt is unable to meet the requirements for continuous development. There are three main routes to improve its quality as ihdicated by research works and commercial production conducted both domestically and in abroad I namely, the adoption of catalytic oxidation process with proper catalysts, the use of two or more feed stocks blended together, and the additionof various quality improvers. This paper presents some works that have been done domestically in this aspect.
