Abstract
The strength and effectiveness of stabilization for subgrade will determine quality of pavement. In order to achieve the required standard of bearing capacity value for soil, some method to increase bearing capacity need to be propose either using chemical or mechanical method. This research focus on chemical stabilization using fine demolished concrete waste (DCW) with the aim to assess concrete waste mix with residual soil to improve bearing capacity of soil as subgrade layer. The proportion of soil to DCW was 4%, 8%, 12% and 16% and being tested using California Bearing Ratio (CBR) at soaked and unsoaked condition to propose optimum percentage mix of the concrete waste to achieve the maximum bearing capacity. Based on this study the optimum percentage for concrete waste particle added is at 8% for both condition which is soaked and unsoaked. Overall the use of DCW considered to be a good soil improvement technique.
