Evaluar el Comportamiento Mecánico para el Método de Compactación Estático Variando la Velocidad de Carga en Especímenes Elaborados con Sub-Base Granular de 5 a 25 mm/min

Abstract

In this investigation the mechanical behavior having a specimen made of material granular subbase from the quarry the Guayuriba river Villavicencio, prepared by the method of static compaction called constant volume variable pressure was evaluated, in which a static force applied by the team Loader 5030 Master which controls the distance and speed of travel of the piston compaction. For carrying out the tests a metal mold galvanized steel A36 in which a total of 25 specimens of 50 mm diameter were produced by 100 mm high with loading rates of 5, it was made 10, 15, 20 and 25 mm/min and maximum compaction force of 36 kN.

The results of the team Loader Master indicated that the granular material being subjected to high compaction speed was 5 mm/min, achieved a greater compaction force by the piston, while the greater speed of 25 mm/min the compaction force was lower. In the Proctor dry density of 2.11 g/cm3 and the specimens manufactured by the method of static compaction is achieved higher densities they were found to this, being 2.32 g/cm3 maximum and indicating that the samples obtained density than 3% higher. Likewise, in the test wave velocity two factors homogeneity were analyzed specimens, the oscillation waves and the speed at which this takes to travel briquette start point to the end.

The results indicate that the method is practical and favorable to be used at slow compaction, but suggests that the static compaction method is not applied with granular materials but with materials containing greater amount of fines.
