The improving of the pile surrounding soil still insufficiently studied. Many researchers treated with the surrounding soil to improve the pile capacity for resisting the lateral loads or liquefaction. Many methods of improvement are adopted to increase pile capacity .Compaction and replacing surrounding soil are adopted in this study as improvement method. Experimental work was executed on pile model using a compression machine. At first tests, were performed on soil to determine soil properties.

The rehabilitation of an existing cracked pavement made of asphalt can be simply done by the installation of new asphalt layers. Due to external forces from traffic and natural temperature variations, existing cracks or joints rapidly propagate out of the old pavement into the new asphalt overlay.

The design and evaluation of pavement structures require a significant amount of supporting data such as subgrade material properties density and cohesion. The present study is undertaken to prepare thematic maps in order to predict the important parameters used in highway pavement design, geometric design, feasibility and other construction projects taking advantage of the ability of GIS tools by using soil investigation reports as a database. Also, these maps are useful in determining the unsuitable soil materials’ position for subgrade in order to avoid or treat any problem.
