摘要
本文有针对性地阐述了国内外沥青改性的发展历程,分析了沥青混合料生产中使用直投式改性剂的技术优势和作用机理,以阿拉善地区高等级公路路面建设为例详细说明了直投式在路面施工中的相关优势。实践证明:直投式沥青混合料改性技术具有良好的经济效益和社会效益,值得大力推广。
The development course of asphalt modification at home and abroad is described in this article,the technical advantages and mechanism of applying in- place mixing of modifier in asphalt mixture production are analyzed,and road constructions of high grade highway in the area of Alashan are used as examples to explain the relevant advantages of in-place mixing technology in pavement construction. The practice has proved that the in- place mixing asphalt mixture modified technology has good economic and social benefits,and it is worth popularizing.
