Correction of the granulometric curve of fine soil using ash from the burning of sugarcane bagasse

In road works, there are cases in which natural soils have inadequate characteristics for their intended use, especially clayey or fine ones, leads to the need find stabilization methods that allow soil present itself as a suitable material its application. Thus, ash, residue generated sugar and alcohol industry from burning of sugarcane bagasse often does not an adequate destination, becomes attractive due granulometry chemical composition. objective was study feasibility correcting granulometric curve Maringá-PR with addition seeking analyze influence this correction through analysis, particle density, limit liquidity plasticity, Unified Soil Classification System (USCS) Highway Research Board (HRB) compaction curve. The results showed incorporation ash remodeled curve, making it similar sandy soil. According HRB USCS classifications, shown A-7-5 high compressibility silt mixture A-6 sand. There also reduction group index, limits well optimal moisture. Therefore, resulted increase texture quality plasticity. Since, applications, correlation found between subgrade material.
