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