Application of Microbial Facilitated Stabilization for Sustainable Improvement of Expansive Pavement Subgrades
Expansive soils, also known as swell-shrink soils, have been a problem for civil infrastructure such as roads and foundations since ancient times. These soils swell and shrink with changes in moisture content, causing buildings and pavements to crack. The reason for this behavior is the presence of the heaving/swelling mineral that expands when exposed to water.
