    <description descriptionType="Abstract">&lt;p&gt;One very important issue is the need for significant improvement of flexible pavement structure&lt;br&gt;
passing over areas of poor soil conditions due to continuous deformation and a low bearing&lt;br&gt;
capacity from the pavement structure foundation. One of the general problem happened on&lt;br&gt;
pavement structure are vertical settlement and lateral displacement of the soil layers. In order to&lt;br&gt;
minimize these problems enhancing the bearing capacity of the subgrade soils can be the major&lt;br&gt;
solution. Mostly, the subgrade soil is known by poor bearing capacity, high plasticity and high&lt;br&gt;
swelling factor. So, the bearing capacity of the soils can be improved by geotechnical ground&lt;br&gt;
improvement. In this study, reinforced subgrade performance with geogrid was numerically&lt;br&gt;
analyzed. Two pavement structure with geogrid reinforced subgrade and unreinforced subgrade&lt;br&gt;
were analyzed under the same traffic load and pavement thickness using finite element model.&lt;br&gt;
ABAQUS software package was used as a tool in analyzing the finite element models of a&lt;br&gt;
quarter of pavement structures&lt;/p&gt;</description>
