摘要
岩沥青作为一种重要的天然沥青改性剂，在国外得到了广泛的应用。随着我国交通运输事业的发展，岩沥青受到了道路界的关注。较为系统的介绍了岩沥青的成因、基本特点、重要产地及两类主要岩沥青的基本性能。进一步介绍了近年来国外的最新研究成果，系统的总结了国内在岩沥青应用与研究领域的进展。最后展望了岩沥青今后在我国北方地区研究的主要方向。
As an important modifier for natural asphalt,the rock asphalt has obtained widespread application abroad. With development of traffic transportation cause, the rock asphalt receives close attention from road circle. The paper systematically introduces the reasons for rock asphalt forming, basic features,impotant producing area along with elementary behavior of two sorts of principal rock asphalt, further introduces the newest fruits in the research, sums up in a systementic way the progress in application and research of rock asphalt at home. At last, it looks forward to major direction of research in Northern Area of our country hereafter.
