A master’s thesis was discussed in the Department of Civil Engineering at the College of Engineering at the University of Kerbala, titled (Experimental evaluations of mechanically-Stabilized soil). The study investigated certain sites of poor-quality soil from the city of Al-Husseiniyah in Karbala. The investigated soils’ ability to withstand the loads imposed on it was improved by reinforcing the upper layers with geogrid, as the upper layers consisted of crushed gravel, class C, and class B, in addition to using base course, to determine the extent of the effect that results from these differences in the layers.
The study aims to reduce the impact of loads placed on the road on weak soils with low bearing capacity by improving the properties of the upper layers of the road using geogrid meshes.
The thesis shows a clear improvement in the bearing capacity of the soil due to reducing the effect of the loads imposed on it through geogrid reinforcement for the upper layers of the road because geogrids have the ability to distribute loads in a regular manner and also have the ability to reduce the lateral displacement of the soil surrounding them. The study also concluded that it is possible to use Class C crushed gravel with reinforcement layers as an alternative to Class B crushed gravel.
The thesis was approved by the discussion committee, which consisted of Professor Dr. Shaker Faleh Shaker / College of Engineering – University of Kerbala (Chairman)
And Assistant Professor Dr. Ayman Jamil Kazem / College of Engineering – University of Kerbala (member), and Lecturer Dr. Saif Muhammad Jawad / Department of Construction and Projects – University of Baghdad (member), Assistant Professor Dr. Raed Rahman Adnan / University of Kerbala – College of Engineering (member and supervisor), and Assistant Professor Dr. Mahdi Abbas Mahdi / University of Kerbala – College of Engineering (member and supervisor).
