| Abstract | A highly plastic soil, classified in the A-7-6 group, was selected
for this study; the stabilizer was fine sand. The swelling mechanism
and factors affecting the values of swell and swell pressure developed by
compacted clay upon access to water are discussed in detail. Swelling
characteristics were investigated by two types of tests, viz. swell
pressure and heave tests. For the heave tests a surcharge of 1 psi,
equivalent to the weight of an 11-in. Portland cement concrete slab, was
used. The results of tests on unstabilized clay showed that the final
values of swell and swell pressure were critical; with these values,
damage to a pavement overlying this soil could result. Upon stabilizing
with fine sand, the final values of swell and swell pressure decreased as
the percentage of sand increased. The effect of surcharge on volume
change was investigated by testing clay samples at optimum water content
under surcharge equivalent to 1, 2, and 3 psi. It was found that
volume changes of clay samples decreased with an increase in surcharge.
The effect of size of sample on volume change was investigated by using
two sizes of apparatus and was found to be not appreciable. |
