改性沥青路用性能浅析

针对公路工程尤其是高速公路工程的沥青路面出现的越来越多的病害,国内外早已开始广泛关注并研究改性沥青,并已取得了一系列重要科研成果并逐步在实际工程中应用、推广。本文结合国内外对改性沥青的研究及应用的基本情况分析探讨了几种改性沥青的相关性能并指出SBS改性沥青是今后我国路用改性沥青的发展方向。

For more and more asphalt pavement diseases in highway and freeway engineering,wide attention and study at home and abroad have already been done on modified asphalt and a series of important research results have been obtained.These results are being gradually applied and popularized in practical engineering.This paper analyzes and discusses related properties of several kinds of modified asphalt and pointed out that in our country SBS modified asphalt will be the development direction of the modified asphalt which is used in highway engineering combining with the basic research and application information of the modified asphalt at home and abroad.
