流态水泥土路用性能研究

Research on pavement performance of uncompacted flowpattern cement-soil

非压实流态水泥土很好地解决了特殊部位回填土难压实的问题。试验表明,流态水泥土对土源要求低,施工流动性好,无侧限抗压强度与土的种类、水泥用量有一定关系,CBR值随无侧限抗压强度的增加而增加,耐疲劳性能、抗冻性能均较好,适宜工程应用。

Uncompacted flow pattern cement-soil has well solved the problem that backfill is hard to compact in special part.The test of uncompacted flow pattern cement-soil shows that its demand of soil source is low,construction flowability is good,unconfined compression strength has a certain relationship with soil type and cement content,CBR value increases with the increase of the unconfined compression strength,and both fatigue and freezing resistance performance is ok.therefore it is suitable for engineering application.
