使用炭黑作为石油沥青的加固剂的研究,国外自1962年以来一直进展着,但是直到现在仍是一个研究课题。 以前的若干调查研究曾表明,使用炭黑添料能增加路面的耐磨性和耐久性、降低石油沥青的温度感应性等等。介绍这类调查研究是本文的重要目的。 与此同时,笔者对国产沥青和渣油提出可供考虑的研究内容。 Research using carbon black as a reinforcing agent for petroleum asphalt has been progressing abroad since 1962, but it is still a research topic until now. Several previous studies have shown that the use of carbon black additives can increase the wear resistance and durability of pavement, reduce the temperature sensitivity of petroleum bitumen and so on. Introducing such research is an important purpose of this article. At the same time, the author put forward the research content that can be considered for domestic asphalt and residue.
