低活性粉煤灰路用可行性评价

Evaluation on the Possibility for Low activity Fly ash Used in Road Base Courses

低活性粉煤灰需要在碱性外掺剂的激发条件下才可用作道路基层材料。从材料的含水量、压实度、碾压成型时间以及低温影响等几个方面论证了这种低活性粉煤灰的应用无需考虑特殊措施，与普通粉煤灰一样有相同的路用可行性。

Fly ash with poor activity can be used in road base courses only blended with alkaline admixture. The possibility for the low activity fly ash used in road is evaluated in this paper according to the research results on the moisture content of the material mixture, the degree of compaction, the delayed compaction process and the effect of low temperature etc., which indicates the fly ash with poor activity is same as the normal fly ash used in highway engineering without special treatments.
