Engineering properties of improved fibrous peat

Depending on the soil type, different types of binder have been used to stabilize soft soils nowadays. An essential criterion in the selection of suitable binder is its capability of achieving the desirable soil stabilizing function. For peat soil, it was evident that the engineering properties of t...
