SMA改性沥青性能及在公路施工中的应用

The Application of SMA Modified Asphalt in Highway Construction

与普通的热拌混合料路面施工相比较，公路改性沥青路面在特别多的高等级公路路面在建成通车之后，就出现了早期破坏等情况，根本达不到15年的正常使用年限。所以，本文对改性沥青与路面施工的问题进行了简要分析。

Compared with the ordinary hot mix pavement construction, much of high grade road of modified asphalt pavement tend to be damaged in the early period after opened, never even normal use 15 years. So, the modified asphalt and the problem of pavement construction are briefly analyzed in this paper.
