A study on engineering properties of compacted lateritic gravels

Abstract

This study aims to apply modified and parallel models to the study of the engineering properties of lateritic gravels. These two models; using the reduction in the maximum grain sizes, are based on the investigation of the in situ grain size distribution of lateritic gravels. The elastic moduli are also estimated by the differential scheme of composite materials in different proportions of laterite to gravels.

The experimental results show that the modified model has a better prediction on both one‐dimensional compressibility and shear strength properties, whereas the parallel one is an effective model for the permeability characteristics. The elastic moduli predicted by the differential scheme are in good agreement with the experimental observations.
