通过一系列室内试验研究,分析了不同固化剂及水泥掺量的砂土混合料在不同龄期时对无侧限抗压强度和劈裂强度的影响,得到了无侧限抗压强度和劈裂强度的主要影响因素及变化规律,并研究了不同延迟时间对混合料7d无侧限抗压强度的影响,给出了固化剂稳定砂土作为高速公路路床、底基层和下基层材料的最佳配合比及其相关的路用性能指标,为实现粉砂土的资源化利用提供了一定的技术基础.
Experimental Study of Performance of Sandy Soil Stabilized by Soil Stabilizer
Through a series of experiments, the influence on unconfined compressive strength and splitting strength of different dosage of soil stabilizer and cement after different days of curing were studied in this paper. The main influence factors of compressive strength and splitting strength and change laws were obtained. And the influence of different delay time on the compressive strength. Optimum proportion and the main road performance indexes of the sandy soil treated by soil stabilizer which was used as highways bed, sub-base and base materials were recommended which provided certain technical basis for utilization of sandy soil.
