Innovative Ground Improvement with Chemical Grouts: Potential and Limits of Partial Saturation with Polymers

Abstract Nowadays, polymers are well-established in geotechnical applications, for example as grouting material soil and rock stabilization, or anchorages. Concerning ground improvement, the act a binder that, if cured, holds grains together by adhesive cohesive forces. This special characteristic enables use of less therefore saves costs but requires detailed knowledge behavior to avoid application errors. The subject this research work two different polymers, which used partial saturation ground. For investigation mechanical hydraulic properties testing program on composite gravel is extended tests, such rheometer chemical grouts. If correctly, can achieve load-bearing capacity comparable that concrete while remaining permeable. highlighted strength tests material. Finally, numerical calculation track ballast using PFC-FLAC3D coupling, demonstrates potential practical even difficult conditions be handled with it.
