Engineered fills are enhanced by compaction to reduce compressibility and permeability. In-situ application of shallow densification methods involve static method with the use of compaction rollers. However, the compaction characteristics of soils are traditionally obtained in the laboratory using dynamic compaction method. Due to the difference in the mechanism of the two compaction methods, there is a variation in the soil fabric formed, quantification of which is scarce. In this research, influence of compaction effort and (dynamic and static) compaction methods on swell and compressibility of two soils of diverse geological formation are investigated. An indirect means of measuring microstructural changes in specimen characteristics using electrical resistivity is also investigated. Results indicate that the compaction effort and the method of compaction have a significant impact on the electrical resistivity and swelling potential. The yield stress of the compacted specimens is also influenced. However, the compressibility and rebound behaviour upon unloading, are obtained to be independent of both the compaction effort and the method of compaction.

通过压实来增强工程填料，以降低可压缩性和渗透性。浅层致密化方法的现场应用包括使用压实辊的静态方法。然而，土壤的压实特性传统上是在实验室中使用动态压实方法获得的。由于两种压实方法的机理不同，所形成的土壤织物存在差异，其量化是稀缺的。在这项研究中，研究了压实作用力和（动态和静态）压实方法对两种具有不同地质构造的土壤的膨胀和可压缩性的影响。还研究了使用电阻率测量样品特性的微结构变化的间接方法。结果表明，压实强度和压实方法对电阻率和溶胀势有显着影响。压实试样的屈服应力也会受到影响。然而，获得的可压缩性和卸载时的回弹行为与压实力和压实方法均无关。
