摘要
高等级公路,尤其是高速公路沥青路面产生早期损坏,除了设计施工方面的原因外,路用沥青的性能较差是重要原因之一,为进一步提高沥青混合料的路用性能,文章简要介绍了改性沥青的生产方法及基本工艺,并探讨了其应用前景。
The early damages often occur on the bituminous pavement of high-l ev el highway especially superhighway. Besides the reasons in aspects of design and construction, the poor performance of highway-used asphalt is one of the impor tant reasons. In order to further increase the highway-used performance of asph alt mixture, this paper briefly introduces the production methods and basic tech niques of highway-used modified asphalt, and probes into its application prospe ct.
