Stabilization Clayey Subgrade Soil Using Waste Materials

Keywords: cement dust, fly ash, compaction properties, waste materials, clay subgrade.Abstract
In the traditional construction of roads, the source materials from borrow-pits are the very common for the roadbed-layers. The construction “total cost” of the roads is affected by important factors such as the source's materials. Enhancing the compaction properties of the local soils for roadbed application with the assistance of selected industry waste materials is found to help reduce the cost of the roads. This work shows the finding of the laboratory compaction study of the local clay subgrade. The compaction was conducted with standard and modified methods on soil mixed with two waste materials (fly ash and cement dust). The influence of waste materials on the clay subgrade compaction behavior was investigated to determine the optimum content of fly ash and cement dust. Finally, the result indicated that the studied parameters were highly influenced by the type of waste materials mixed with it.
