| Abstract | This research was conducted, to investigate the physical behavior
of clay soil stabilized with marl, as compared to stabilization with
lime. The clay and marl used were analyzed for chemical composition.
Clay was mixed with lime or marl in separate tests at 0, 2, 5» 7> 10, and
12 percent by weight. Atterberg limits, specific gravity, classification,
and compaction characteristics of the clay and the marl and lime stabilized
samples were determined. Unconfined compressive strength and CBR tests
were utilized to determine the strength properties of the stabilized soil
samples.
The results of laboratory testing indicate a reduction in plasticity
index when lime is added to clay. The strength properties of the mixture
were found to vary directly with the amount of lime added. The cementing
process in lime stabilization was found to develop gradually as time in¬
creases. The reductions in density and swell which occur when lime is
added to clay are significant.
Physical properties of clay-marl mixtures improved to a smaller
degree than observed for clay-lime samples. The density of the soil mass
increased with the amount of marl used; an expected reduction in the plastic
range of clay-marl mixes did not occur. The strength properties of clay,
as measured by the CBR value, decreased rapidly at high percentages of
marl. The swell of submerged clay-marl specimens was undesirably great. |
