This final report presents the findings of the Ground Improvement for Khulna Soft Clay Soil research project in Bangladesh. This study collates the relevant findings from existing research, field observations and ground investigation to understand the effectiveness and limitations of existing ground improvement techniques implemented in Khulna region, and to develop appropriate recommendations to overcome the typical construction challenges for road embankments and structures in the region. Using the results gained observational ground models have been developed for to help better understand the deformation mechanisms and assess the likely contributory causes. Ground improvement techniques are presented that are considered either (a) technically feasible and (b) within the likely budget for rural road construction together with guidance for implementation to deal with specific construction issues. Topics for further research are presented that will improve the ability to apply ground improvement techniques in Khulna Region.
