This paper presents the study of treatment of an expansive soil with vegetal fbres. The soil studied is swelling clay from the
region of Souk Ahras (Algeria). The use of fbres as reinforcement has shown a certain efciency which increases the bond
between the soil grains due to the friction between the soil particles and the fbre material. The vegetal fbres used are DISS
crushed fbres. The infuence of the vegetable fbre content on the global behaviour of the soil is studied; by highlighting
the role of the inclusion rate of fbre in the soil mass (1, 2 and 3% of content by weight), this will be studied by a series of
behaviour and mechanical performance tests. The DISS fbres have undergone chemical-thermal treatment to extract the
sugars and soluble substances contained in the vegetal to avoid the decomposition of the latter in the soil. The results will be
compared to those of unreinforced soil. Experimental results show that the swelling potentials are reduced by the addition
of vegetal fbres, the cohesion of the soil treated is increased, and the soil is more ductile. It has also been shown that 2% of
the DISS fbre content is a critical value for reducing the swelling potential of the clay soil.
