关于Superpave沥青混合料设计方法的评述

Review of superpave asphalt mixture design method

美国Superpave沥青混合料设计方法在试件成型、技术指标和标准等方面,与马歇尔试验方法相比较有了很多的进步,但同时也还发现存在所设计沥青用量偏少、难以压实而渗水等问题,需要继续研究与改进。因此学习借鉴其合理的部分是必要的,但不可盲目照搬。

The America superpave asphalt mixture design method made great progress in specimen making,performance index and standard compared with Marshell method.But asphalt content designed by it is lean to lower than needed,and cause compaction difficulty and leakage,so it need more research.Hence it is necessary to learn from its positive part but more important to avoid eyeless copy.
