Compaction Characteristics of Crushed Solidified Soil
Since soil material produced at construction sites is soft, it is mixed with a stabilizer (e.g., cement, lime) as a way to use it more effectively if it cannot be used for earthworks as such. By mixing soft soil with a stabilizer that enhances strength, this method improves the soft soil. However, as solidification continues to progress after construction, the material may become stronger than is necessary, complicating re-excavation. If constructed on soft ground, it may also cause cracking of an earth structure because it cannot follow ground subsidence. Therefore, the authors focused on crushed solidified soil as a material with low strength development even when mixed with a solidifier and conducted studies on its use as a civil engineering material. Crushed solidified soil is prepared by mixing the target soil with a solidifier and crushing it after a certain period of time to make it compactable. If an embankment is constructed using crushed solidified soil, it is considered appropriate to use a quality management method based on the degree of compaction as with construction using ordinary soil. Therefore, we conducted a compaction test on crushed solidified soils prepared using several different soil materials as well as different conditions. As a result, it was found that the compaction curve of crushed solidified soil was influenced by the original soil, solidifier, time mixing with a solidifier to crushing and time from crushing to the compaction test.
