Abstract
En el Perú, uno de los problemas principales para promover el desarrollo de muchas localidades alejadas y pobres, es no contar con vías asfaltadas ya que en la mayoría de los suelos no cuentan con las propiedades mecánicas adecuadas de la subrasante.
En la presente tesis es la mejora de la carretera Pilluana – Paraíso, el cual se
ha investigado el efecto sobre las propiedades físico- mecánicas del suelo con dos estabilizadores químicos más utilizados por diferentes empresas en el rubro de la construcción de carreteras.
Los aditivos que se van a estudiar son PROES y CONAID, producidas por las empresas PROES PERU SAC y TDM Grupo, respectivamente. Estos
productos son estabilizantes a base de aceites sulfanados, lo cual es su
principal propiedad para incrementar la resistencia de los suelos arcillosos.
Los estabilizadores son componentes químicos que ayudan a mejorar las propiedades de resistencia del suelo, como propuesta para la mejora de la
subrasante de la carretera en mención, Se realizó las comparaciones de suelo
natural y suelo mejorado a partir de los resultados del ensayo de CBR,
mediante datos recolectados de investigaciones realizadas.
El objetivo de esta investigación es determinar el efecto de la aplicación de
estos aditivos a través de sus dosificaciones dadas en su ficha técnica para
mejorar la capacidad portante (CBR) de la subrasante de la carretera Pilluana -
Paraíso. Asimismo, compararlas para determinar cuál de los dos presenta un
mayor incremento en las propiedades mecánicas del suelo. Para las muestras
obtenidas se realizaron calicatas a lo largo de la vía no asfaltada, se realizaron
los ensayos físicos y mecánicos para el suelo natural, en el suelo con los
aditivos líquidos (PROES y CONAID) y en el suelo con los aditivos sólidos
(PROES + CEMENTO y CONAID + CEMENTO). Todos los ensayos fueron
llevados a cabo en el Laboratorio de Mecánica de Suelos particular, en base a
las normas técnica peruanas. Nuestros resultados demuestran que el suelo es
limo - arcilloso, según la clasificación SUCS y AASHTO. Por otro lado, el porcentaje de CBR máximo para el suelo natural fue de 3%, lo cual, según el
MTC, es una subrasante inadecuada. En el caso del suelo modificado con los
aditivos líquidos PROES y CONAID, el porcentaje de CBR máximo es de 13%
y 10%, lo cual corresponde a una subrasante buena.
Finalmente, para los aditivos sólidos PROES y CONAID, el porcentaje de CBR
máximo es de 70% y 58%, lo cual corresponde a una subrasante excelente, se
concluye que ambos aditivos sólidos PROES y CONAID mejoran las
propiedades mecánicas, lo cual teniendo en cuenta que se usara el aditivo
CONAID por aplicarse menos dosificación y resulta más barato para estabilizar
los suelos de la carretera Pilluana – Paraiso, provincia de Picota, San Martín.
In Peru, one of the main problems to promote the development of many remote and poor localities is not having asphalt roads since in most soils they do not have the adequate mechanical properties of the subgrade. In the present thesis it is the improvement of the Pilluana - Paraíso highway, which has investigated the effect on the physical-mechanical properties of the soil with two chemical stabilizers most used by different companies in the field of road construction. The additives to be studied are PROES and CONAID, produced by the companies PROES PERU SAC and TDM Grupo, respectively. These products are stabilizers based on sulphated oils, which is their main property to increase the resistance of clay soils. Stabilizers are chemical components that help to improve the resistance properties of the soil, as a proposal for the improvement of the subgrade of the road in question, Comparisons of natural soil and improved soil were made from the results of the CBR test, using data collected from research carried out. The objective of this research is to determine the effect of the application of these additives through their dosages given in their technical sheet to improve the bearing capacity (CBR) of the subgrade of the Pilluana - Paraíso highway. Likewise, compare them to determine which of the two presents a greater increase in the mechanical properties of the soil. For the samples obtained, pits were made along the unpaved road, physical and mechanical tests were carried out for the natural soil, in the soil with the liquid additives (PROES and CONAID) and in the soil with the solid additives (PROES + CEMENTO and CONAID + CEMENTO). All tests were carried out in the particular Soil Mechanics Laboratory, based on Peruvian technical standards. Our results show that the soil is silty - clayey, according to the SUCS and AASHTO classification. On the other hand, the maximum CBR percentage for the natural soil was 3%, which, according to the MTC, is an inadequate subgrade. In the case of soil modified with PROES and CONAID liquid additives, the maximum CBR percentage is 13% and 10%, which corresponds to a good subgrade. Finally, for the solid additives PROES and CONAID, the maximum CBR percentage is 70% and 58%, which corresponds to an excellent subgrade, it is concluded that both solid additives PROES and CONAID improve the mechanical properties, which taking into account that the CONAID additive was used because less dosage was applied and it is cheaper to stabilize the soils of the Pilluana - Paraiso highway, Picota province, San Martín.
