Resumen
Esta investigaciĆ³n tiene como objetivo principal dar a conocer el Cloruro de Calcio (CaCl2) en soluciĆ³n como estabilizador de suelos no pavimentados, introduciendo esta sal como aditivo en el agua de amasado para las carpetas de rodado.
El trabajo comienza con una investigaciĆ³n de los caminos de la regiĆ³n en estudio, validando las necesidades para la existencia de mejores caminos en la zona y una introducciĆ³n a la estabilizaciĆ³n de suelos.
Luego se presenta las propiedades del CaCl2 y la metodologĆa de aplicaciĆ³n del producto, en la estabilizaciĆ³n de carpetas de rodado. AsĆ tambiĆ©n se seƱalan los materiales y mĆ©todos utilizados para evaluar esta sal por intermedio de ensayes de laboratorio, estudiando los efectos sobre las propiedades fĆsicas y mecĆ”nicas del suelo.
Como conclusiĆ³n general no se puede validar el producto como una alternativa concreta para la estabilizaciĆ³n de suelos, en la regiĆ³n en estudio, ya que, debido a su capacidad de absorber la humedad ambiente, no aporta capacidad de soporte al suelo.
Sin embargo, el producto le aporta al suelo caracterĆsticas que son destacables, tales como la reducciĆ³n del Ćndice de Plasticidad y disminuciĆ³n de la Humedad Ć³ptima de compactaciĆ³n. El producto es eficaz para evitar la formaciĆ³n de polvo y reducir fuertemente la uniĆ³n hielo ā pavimento.
The main objective of this investigation is to present Calcium Chloride (CaCl2) as a solution for the stabilization of unpaved roads, introducing this salt as an additive in lake water surface mixes. The work begins with an investigation of the roads in the studied region, showing the need for the existence of better roads in the zone and an introduction to soil stabilization. The properties of Calcium Chloride and the methodology of application of the product in the stabilization of unpaved roads are introduced. Furthermore, the materials and methods used for evaluating this salt using laboratory tests, studying the effects on the physical properties and soil mechanics are presented in detail. As a general conclusion, the product cannot be validated as a concrete alternative for the stabilization of unpaved roads in the studied region, since it does not contribute additional strength to the existing soil, due to its capacity of absorb moisture from the surrounding environment. However, the product does contribute commendable properties to the soil, such as: lowering the Plasticity Index and diminishing the compaction's Optimal Humidity, by increasing the value of the Dry Compaction Maximum Density, effective in avoiding the formation of dust and strongly reducing the ice ā pavement union.
