Influence of the Load and Time Conditions on the Results of the Static Plate Load Test

CODEN: JTEVAB

Abstract

In this article, the authors analyzed the influence of the loading time, magnitude, and loading approach (loading device type and weight) on the vertical displacements registered in the pavement subgrade static plate load test. The three-dimensional finite element method computational model was developed. Conducted numerical analyses were verified in field tests. Three layer systems of different stiffnesses were examined. The visco-plastic behavior of the subgrade was taken into account in the numerical computations as well as the reach and superposition of the deflection (displacements) basins at different loading configurations (loading device type and weight). Essential discrepancies in both the field measurement results and computation results were observed for different loading times and approaches at the same loading level of the plate. The ambiguity of the pavement subgrade static plate load test results interpretation due to different load-time test conditions was explained.
