INTRODUCTION 1.1. Background Roads and Highways Department is responsible for the construction and maintenance of the major road network of Bangladesh. The mission of the Roads and Highways Department is to provide safe, cost effective roads and bridges. To construct safe, cost effective roads and bridges, Engineering Soil Map may play important role as planning tool. If we have appropriate information regarding soils of Bangladesh, we can plan design and construct roads and bridges economically and provide safety during construction. To prepare an Engineering Soil Map of Bangladesh, it needs both time and manpower. Thus the Engineering Soil Map of whole Bangladesh cannot be made all at once. It is a continuous process and has to be made in phase. BRRL has prepared Engineering soil map of 49 districts of Bangladesh. As a part of the continuous process in financial year 2016-2017, an initiative has been taken to complete mapping
