Comprehensive Methodology for the Evaluation of Clay Expansiveness. A Case Study

Abstract

Although expansive soils have been widely studied by different authors, just a few have made methodological proposals to comprehensively evaluate this phenomenon. The aim of this paper is to suggest a methodology which will serve as guideline to evaluate soil expansiveness in a comprehensive way. This methodology comprises a series of tasks: identification and classification of potentially expansive soils, estimation of the active zone depth, quantification of the expansion, calculation of heave and choice of a solution.
