Evaluating laboratory experiments used to find the characteristics of the expansive soil in the new administrative capital.
Expansive soils are globally problematic geomaterials known for their high swell properties and low strength behavior. Precise determination of the swell parameters is required for the proper design of structures on expansive soils. The presented lab-based experimental study assesses fundamental swell properties of undisturbed and remolded samples of the expansive soil taken from the new administrative capital city of Egypt. The laboratory investigation is completed by estimating the swell characteristics of the tested soil using empirical swell prediction models based on laboratory index properties, including water content, density, moisture, clay minerals content, and non-expansive materials content. Interpretation of the results obtained reveals a significant difference between the swell characteristics of the undisturbed and remolded soil samples. The study shows that prediction models tested yielded swell characteristics that are acceptable within the standard error limits.
