岩沥青常被用作为沥青路面的添加剂,已在国内外一些工程中得到应用。本研究用韩国SK基质沥青和台湾CPC基质沥青分别对不同掺量岩沥青胶结料性能进行了比较分析。采用AC-25沥青混合料,基质沥青为韩国SK-70号沥青,分别对不同掺量岩沥青改性沥青混合料性能进行了比较分析,推荐了岩沥青的适宜掺量。
Rock asphalt is often used as an additive to asphalt pavement and has been applied in some projects at home and abroad. In this study, the performance of rock cement with different content of rock asphalt was compared with SK matrix asphalt in Korea and CPC CPC asphalt in Taiwan respectively. AC-25 asphalt mixture was used as base asphalt for SK-70 asphalt in Korea. The performance of asphalt mixture with different content of rock asphalt was comparatively analyzed respectively, and the appropriate dosage of rock asphalt was recommended.
