Stabilization of Nigerian Deltaic Laterites with Saw Dust Ash
Journal Title: International Journal of Scientific Research and Management - Year 2014, Vol 2, Issue 8
Abstract
Soil improvement potential of saw dust ash was studied with regards to compaction and CBR characteristics of a deltaic laterite. The physical properties and engineering characteristics studied include the moisture content, Atterberg limits, compaction characteristics, CBR and unconfined compressive strength (UCS). The values of CBR obtained in the tests are within the limits recommended by the Asphalt Institute for highway subbase and subgrade. It is concluded that saw dust ash, an industrial waste, is a cheap satisfactory stabilizing agent for sub base in lateritic fills; although its performance can be improved by combining it with other bonding materials such as lime, and becomes an alternatives use of industrial waste to reduce the construction cost of road particularly in the rural areas of the country.
