大量研究成果和长期实践经验表明:粉煤灰石灰类道路基层,在一定温度、湿度下,强度随龄期增长,后期强度很高;具有良好的水稳性、板体性和较好的抗冻性能.虽然还存有早期强度较低和可能会发生一定程度收缩裂缝的欠缺,但仍不失为一种路用性质优良的半刚性基层.现将研究成果与应用意见,择要简介如下,以供参考.
A large number of research results and long-term practical experience show that: the fly ash lime road grassroots level, under certain temperature and humidity, the strength increases with age, the late strength is high; has good water stability, board and good resistance Frozen performance.Although there is still a lack of early strength and may be some degree of shrinkage cracks, but still be a kind of semi-rigid grassroots with excellent road properties.Research results and application of the views, the choice is as follows, with for reference.
