Study in laboratory of treatment with cement of silty material: improvement of the mechanical properties

摘要: The addition of the agent treatment allows to obtain a better traficability and improves capacity soil compaction while assuring correct implementation. Besides, binder provides direct, maintained, or increasing lift at same time. choice its dosage is determined by type soil, moisture content time treatment, aimed characteristics. technique in place hydraulic binders consists valuing natural (existing site construction) mixing them with some water. It avoid transport implies their stabilization very interesting costs before implementation superficial layers. In this context, paper presents results shear strength parameters study laboratory aim using fine particular an Algerian western resulting silt, after cement dry method. Our goal realize pavement structures (base layer subgrade layer) material. This requires know well material which we wish treat. A geotechnical complete characterization approached on samples compacted different water content, followed influence 2, 4, 6 % characteristics portance shearing. Shear test was performed curing for 24 h evaluate parameters. obtained highlight clearly marked improvement such as
