AIASSA, Gonzalo M  and  ARRIA, Pedro A.. DISEÑO DE MEZCLAS DE SUELO COMPACTADO PARA LA CONSTRUCCIÓN DE TERRAPLENES. Rev.EIA.Esc.Ing.Antioq [online]. 2007, n.7, pp.51-61. ISSN 1794-1237.

The highways or airfield pavement performance depends on the material behavior in different structural layers of embankment. Generally, economic limitations force to use of in situ available soil as material for pavement construction. The improvement of soil by compaction and mixture with granular or stabilizing material is an adequate strategy. In this work, a study of mechanical behavior of silty-sand soil has been made, and the aptitude of use it as sub-base material has been evaluated. The soil analyzed corresponds to superficial layers in the central region of Argentina (southern zone of Cordoba province). The mechanical characterization has been made in laboratory, with unconfined compression and CBR tests on compacted soil-cement and soil-granular material. The results has shown materials characterization and concluding of the use and performance on compacted soil sub-base pavements construction.

Keywords : flexible pavement; silty-sand; soil improvement; mechanical behavior.
