Use of Wicking Fabric to Help Prevent Differential Settlements in Expansive Soil Embankments
Publication: Geo-Frontiers 2011: Advances in Geotechnical Engineering
Abstract
Expansive soils cover one-fourth of the U.S., and damage to infrastructure from expansive clays is huge every year. A new type of Wicking Fabric (MNWF) has high specific surface area (consequently high wettability and high capillary action) and high permeability. It shows great promise as a cost-effective means of controlling moisture migration and subsequent differential settlement in expansive soils. This paper is intended to investigate the performance of the MNWF as a capillary barrier in expansive soil embankments through numerical simulations. Eight different combinations were considered and the simulation results were discussed.
