压实士在润湿作用后的表现如何,要看润湿作用的强烈程度和路基土的压实程度而定。在西北缺水地区,由于湿源不足,路基土可以在低于最佳含水量时压实。此时,压实土在润湿后的强度反较在最佳含小量值时压实的小。借助于增加压实工作量而获得的高密实度的土,在反复干湿的作用下,是能保持较高的水稳定性的。因此,在缺水地区我们可以在较低的天然湿度下进行压实;同时也可以用较重的来压实工具压实,此时可获得高强度的土。
The behavior of a compacter after the wetting effect depends on the degree of wetting and the degree of compaction of the subgrade soil. Sub-surface soil can be compacted below the optimal moisture content due to insufficient wet sources in the northwestern water-scarce regions. At this point, the strength of the compacted soil after wetting is compacted less than optimal with small values. High density soil, which is obtained by increasing the compaction workload, maintains high water stability under repeated wet and dry conditions. As a result, we can compact at low natural humidity in areas where water is scarce, and at the same time, we can compaction with heavier compaction tools where we get high-strength soils.
