水泥（石灰）粉煤灰混合料路面基层成型延迟时间研究

Study on the Compacting Delay Time of Cement(Lime)Pfa Mixture Base Course

本文通过室内试验和试验路施工、测试，研究了水泥（石灰）粉煤灰混合料路面基层的最长成型延迟时间，得出了这种混合料基层的成型延迟时间宜控制在２４小时内的结论，并用Ｘ衍射方法对其进行了分析证明。

The compacting delay time of cement(lime)pfa mixture is studied in this paper,It is concludedthat the longest compacting delay time of cement(lime)pfa mixture had better be limited within twen-ty four hours.
