弹性体改性沥青涂盖料的低温拉伸性能研究

Study on low temperature tension performances of elastomer modified asphalt coating

通过延度试验对弹性体改性沥青涂盖料的低温拉伸性能进行了测试分析,研究了SBS型号、基质沥青、相容剂含量、配合剂种类及含量、填充料种类及含量对改性沥青涂盖料延度性能的影响。结果表明,延度可以比较全面地反映弹性体改性沥青涂盖料的低温拉伸性能,是评价弹性体改性沥青涂盖料低温性能简单有效的方法。

The low temperature tension performances of elastomer modified asphalt coating were studied by force ductility tests. The effects of SBS type, asphalt properties, compatilizer content, additives and its content, filler and its content on force ductility performances of elastomer modified asphalt coating were investigated. Test results indicate the force ductility test is a simple and effective means showing low temperature tension performances of elastomer modified asphalt coating.
