我国重交通道路沥青的发展

THE DEVELOPMENT OF PAVING ASPHALTS FOR HIGH TRAFFIC VOLUME

简要回顾了我国重交通道路沥青发展历程的三个阶段 :初始阶段 -中国1号沥青等的成功开发 ,结束了我国不能生产重交沥青的历史 ;拓展阶段 -随着中东、新疆等原油用于重交沥青的开发 ,拓宽了原料来源 ,缓解了供需矛盾 :提高阶段-通过技术攻关 ,一批企业重交沥青的质量迈上了新台阶 ,较之 ESSO沥青亦毫不逊色。最后 ,针对重交沥青市场仍不景气的现实 ,从原料来源、国际交流、沥青改性、市场开拓等方面提出了若干建议。

This paper reviews briefly three stages of the development course of paving asphalts for high traffic volume in China In the first stage,the successful producing China No 1 Asphalt finished the history,in which paving asphalts for high traffic volume couldn’t be produced In the second stage,with producing paving asphalts for high traffic volume by Middle Eastern and XinJiang Crude Oil etc ,the raw materials sources for paving asphalts were increased and the contradiction between supply and demand was mitigated In the third stage,by technological developing,the quality of paving asphalts for high traffic volume in many enterprises was raised to a new level Finally,to face the actual circumstances of the asphalt market slump,this paper makes some suggestions on raw materials sources,international exchange,asphalt modifying and opening up market etc
