Engineering approaches for road construction projects and determination of geotechnical design parameters : Road network improvement of northern Iraq

Abstract EN

Transport in northern Iraq becomes an important issue in terms of trading due to its geographical position.

Road construction between Darbandikhan and Kalar villages in the northern part of Iraq is crucial for the connection of Erbil and Suleymaniye to northeast.

The planned road construction requires a detailed environmental and geotechnical study in order to determine geo-engineering parameters of ground conditions.

For this purpose, this study is carried out to highlight the engineering geological and geotechnical features considering the groundwater conditions of the Darbandikhan-Kalar road route section.

In this context, field and laboratory works were performed along the projected route.

Within the scope of field studies, an engineering geology map was generated, a suitable routing was specified, and drilling and in-situ testing was completed.

Seven boreholes and total of 196,5 m geotechnical purposed drilling works were performed along the planned route section.

The core samples obtained from drilling works are utilized for laboratory testing.

As a result of this study information about the bearing capacity, slope stability and basic soil parameters were determined and no problems were encountered.
