Strength and Structure of Laterites and Lateritic Soils.

Abstract

Nine soils derived from basalt and five soils derived from volcanic ash, all from Hawaii, were subjected to shear strength tests, engineering index tests, pore size distribution measurements, slaking tests, scanning electron microscopy, x-ray analysis, and thermo-gravimetric analyses. Relationships are established between the quantitative mineral contents and the engineering behavior of the soils according to the relative degree of weathering that the soils have experienced. These relationships suggest a classification for basalt derived soils based upon the specific gravity of the solids and the void ratio of the soil. No classification system is proposed for ash derived soils but the limited data suggest a system similar to that for the basalt soils might apply. (Author)
