Dimensionamiento de estructuras de pavimento en función del contenido de cal o cemento en la subrasante

Abstract

La ganancia de resistencia incide en el dimensionamiento de las estructuras de pavimento y los espesores de las capas asfáltica, base y subbase en su costo final. De acuerdo a lo anterior se realiza el análisis de las ganancias de resistencia obtenidas por medio de pruebas CBR, datos extraídos del documento “ Variación de las propiedades mecánicas de suelos arcillosos compresibles estabilizados con material cementante” (Luis Gómez, 2016) en el cual se realizaron unos análisis de un suelo de material limo-arcilloso con arenas de color marrón naranja de alta plas¬ticidad (MH) según el S.U.C.S, A-7-5(20) según la AASHTO, al cual se le adicionaron porcentajes de Cal y Cemento que para este estudio nos centramos en los valores del 3%, 4%, 5% y 6% para cada material cementante. Los valores de CBR obtenidos del estudio consultado en la literatura, se manejaron como base para obtener el Módulo de Resiliencia que de aquí en adelante será Mr de las subrasantes por medio de las correlaciones recomendadas por el “Manual de diseño de Pavimentos Flexibles para Bajos Volúmenes” (INVIAS, 2007), y estimaron volúmenes de transito de 2´000.000 de ejes equivalentes con el fin de observar el comportamiento de los datos de diseño para este caso. De acuerdo con estos volúmenes de transito se determinaron los valores de Deformación de tracción admisible sobre la capa asfáltica y de Deformación vertical admisible; sobre las capas granulares y se procedió a realizar la modelación de las estructuras de pavimento en el software Kenpave, de acuerdo con cada uno de los valores de Mr obtenidos de las subrasantes tratadas, para después realizar el análisis económico basado en los resultados de diseño The gain in resistance affects the dimensioning of the pavement structures and the thickness of the asphalt, base and sub-base layers in their final cost. According to the above, the analysis of the resistance gains obtained by means of CBR tests is carried out, data extracted from the document "Variation of the mechanical properties of compressible clayey soils stabilized with cementing material" (Luis Gómez, 2016) in which carried out some analyzes of a soil of silt-clayey material with orange-brown sands of high plasticity (MH) according to the SUCS, A-7-5(20) according to the AASHTO, to which percentages of Cal and Cement that for this study we focus on the values ​​of 3%, 4%, 5% and 6% for each cementitious material. The CBR values ​​obtained from the study consulted in the literature were used as the basis for obtaining the Resilience Modulus, which from now on will be Mr, of the subgrades through the correlations recommended by the "Design Manual for Flexible Pavements for Low Volumes". ” (INVIAS, 2007), and estimated traffic volumes of 2,000,000 equivalent axles in order to observe the behavior of the design data for this case. According to these traffic volumes, the values ​​of allowable tensile strain on the asphalt layer and allowable vertical strain were determined; on the granular layers and proceeded to model the pavement structures in the Kenpave software, according to each of the Mr values ​​obtained from the treated subgrades, to then carry out the economic analysis based on the design results.
