—Nowadays, strength characteristics of soils have
more importance due to increasing building loads. In some
projects, geotechnical properties of the soils should be improved.
Geotechnical engineers generally use waste materials to
improve soil properties but most of these materials have toxic
substances such as heavy metal slags, fly ash, silica fume and
In this study, the effects of the addition of a plant gum,
named as astragalus, grown commonly in Central and East
Anatolia, Iran, Iraq, Turkmenistan and Transcaucasia, on the
stability and strength parameters of cohessionless soil were
investigated. Astragalus is a pure natural and environmental
friendly material. Ground water directly affected by soil
additives which used for soil improvement.
In this investigation, properties of a cohessionless soil were
stabilized by using astragalus. In order to find out which rate of
the additive caused maximum strength parameters of the soil
samples which prepared by using four different replacement
amounts of 0%, 3%, 5% and 10% by weight of soil. Maximum
dry densities and optimum moisture contents were determined
for each mixture. Strength parameters of each mixture were
also determined. According to experimental study, adding 1%
of astragalus content is convenient for sandy soil when
considered strength parameters and economical respect of
