| 摘要： | In highway construction, loose embankment and subgrade soils must be compacted to increase their density. Compaction increases the strength characteristics of soils, and thus increases the bearing capacity of the pavement constructed above them. However, for a variety of reasons, road grades sometimes do not allow for much clearance between the pavement section and the groundwater table. When an adequate separation is not provided between the stabilized subgrade and the groundwater table, difficulties in compacting the stabilized subgrade often result. Research was conducted to determine the minimum separation required between the bottom of the stabilized subgrade and the groundwater table. |
