In this study the effect of using a biopolymer soil stabilizer on soil stiffness characteristics
was investigated. Chitosan is a bio-waste material that is obtained by chemical treatment of …

The strength of marl soils decreases drastically in the variation of the water content. This has
caused such soil to be introduced as problematic soil in geotechnical projects. In the present …

Chitosan is becoming increasingly applied in agriculture, mostly as a powder, however little
is known about its effect on soil mechanical properties. Uniaxial compression test was …

Due to the environmental impacts of conventional soil stabilization materials, such as
cement, ongoing efforts have been carried out by different researchers to find alternative …

Civil and geotechnical researchers are searching for economical alternatives to replace
traditional soil stabilizers such as cement, which have negative impacts on the environment …

Recently, chitosan biopolymer has attracted several research attentions in
geoenvironmental applications such as absorption of heavy metals in contaminated soils …

The small-strain shear modulus (G max) is also a key parameter in the dynamic analysis of
the soil behavior at the range of small strains. Unconfined compressive strength (qu) is one …

The current study evaluated the potential of crustacean polysaccharide and protein-based
biopolymers, namely, chitosan and casein, in ameliorating a low organic soil. The inclusion …

The performance of an environmentally friendly biopolymer synthesised from secondary
resources to overcome the wind erosion of sandy soil was investigated in this study. The …

ABSTRACT A Gypsum soil is an example of problematic soils and susceptible to large
volumetric deformations when they become saturated. Various structures for instance: roads …
