Abstract
The main objective of this research is to evaluate the improvement of embankment
soil foundation soil using the fiber glass treatment. To accomplish the main objective,
laboratory tests, includes direct shear test and unconfined compression test are made to
evaluate the potential of acting the fiber glass as cementing agent in terms of strength
parameters (cohesion and angle of internal friction). The ANSYS program of version
(12.1) was employed for analyzing embankment foundation system. The results
showed that increasing the percent of fiber glass from (1 to 3%) reduce the vertical and
horizontal displacement about (75%) at 3%, and reduced the horizontal and vertical
strain about (75%, 85%) respectively at the same fiber glass content (3%). This means,
that the general role of adding the fiber glass works as a tender to soil mixture not as
fiber reinforcement. So it can be concluded that the fiber glass act as cementing agent
as shown in the obtained experimental results for strength parameters (cohesion and
angle of internal friction ) from the direct shear and the unconfined compression test
that carried out in this works.
