为了提高灰土类基层的路用性能,提高其早期强度与水稳性、抗冻性,更有效地利用石灰、粉煤灰资源,以及延长工程施工期限的要求。由我院和河南省交通厅公路局协作进行的“石灰、粉煤灰加固土性能研究”课题于1986年6月通过了河南交通厅主持的鉴定。该项研究从1985年12月开始,以磨细生石灰的应用为主,结合粉煤灰的利用开展试验研
In order to improve the road performance of the soil-based grassroots, improve its early strength and water stability, frost resistance, more effective use of lime, fly ash resources, as well as to extend the construction period requirements. The project “Study on the Properties of Lime and Fly Ash Reinforced Earth” conducted by our institute and the Highway Bureau of Henan Provincial Communications Department passed the appraisal conducted by Henan Communications Department in June 1986. The study from December 1985 onwards, mainly to the application of ground lime, combined with the use of fly ash to carry out experimental research
