Clay soil is a that causes lot of problems, has low permeability and difficult to handle in the field. The grains are very fine composed minerals can be affected by water. If water content high this expands its strength decreases significantly damage structure above it. To overcome problem, researchers tried use brick waste as mixing material, because material commonly found composition bricks 0%, 10%, 15% 20%, tests carried out include Atterberg test, grain size analysis, compaction test. For CBR test free compression at maximum solid condition. Tests were both on samples had been mixed with waste. results show reduce plasticity, it seen decrease liquid limit value (LL), plasticity index (PI) compressive (qu) soil. While density, (soaked, unsoaked) initially increases, percentage these values decrease. best achieved content.
