Abstract

This study explored the effects of lead (II) nitrate on the geotechnical properties of two soil samples. The geotechnical properties of the natural soil samples were determined prior to their contamination with lead nitrate. The samples were then contaminated with 500 ppm, 1000 ppm and 2000 ppm of lead (II) nitrate and cured for 1, 14 and 28 days. The geotechnical properties of contaminated soil samples were determined after each of the curing periods. Results show that the maximum dry unit weights of the samples generally reduced with increasing concentration of lead nitrate and with increasing curing period. The optimum moisture contents of the samples increased with increasing curing period but reduced with increasing concentration of lead nitrate. However, an increase in the CBR after 28 days curing period was noticed for the samples as the concentration of the lead nitrate increased. The contaminated soil samples are suitable for use as subgrade and subbase materials for road pavement construction.
