| Abstract | This thesis presents the results of using sand to stabilize a lateritic soil having high percentage of fines, high liquid
limit and plasticity index. Effect of sand on physical properties of the lateritic soil was first to be determined. After that compaction and CBR tests were performed and the effects of sand on moisture-density relationships and CBR of the lateritic soil-sand mixtures were evaluated. The compaction was performed on both fresh and re-used soil samples and the effects of re-using soil sample on compaction characteristics and CBR were also studied. Results showed that the response to sand stabilization of the lateritic soil studied is promising, and could be considered feasible. On the basis of the test data, it was indicated that the liquid limit and plasticity index decrease as the percentage of sand increases. The magnitude of decrease in plasticity index is proportional to the increase in percentage of sand. For the lateritic soil used, there is an optimum sand percent at which maximum density is attained. Each CBR test was performed after
compaction and the results show that the maximum unsoaked CBR and maximum soaked CBR occur at moisture content about 17, dry of the
optimum. The optimum sand contents for maximum unsoaked CBR are somewhat less than those indicated by the compaction tests, whereas
the optimum sand contents for maximum soaked CBR are about the same as those indicated by the compaction tests. The curves of unsoaked and soaked CBR performed on samples compacted at optimum
moisture contents are irregular on changing in the sand content.
Comparison of both compaction curves obtained from using
fresh soil samples and re-used soil samples shows that the
re-used soils give higher maximum densities and the optimum sand percent is somewhat greater. The effects of reusing soil sample on CBR are (1) decrease in the unsoaked CBR, and (2) very little difference in the soaked CBR. |
