  • Applied Research Using a Transparent Material with ...

    An innovative material, transparent soil, was used to study flow from a prefabricated vertical drain (PVD). Transparent soil is a mixture of mineral oil, solvent, and amorphous silica. Before using the material to study PVD flow patterns, testing was completed to verify previously published values for hydraulic conductivity and porosity.

  • Soil Investigation for Construction of Bridges and Culverts

    In the case of culverts and minor bridges, there is only the need for a qualitative idea of the various soil layers. If there is no rock present, the representative samples are taken. These are obtained from the borings at 1 to 1.5m intervals. This interval decision depends on the continuity of the soil type or a change in the type of soil.
