ABSTRACT: The aim
of this research is to study the effect of compaction energy on Jerash cohesive
soil. Qualitative and quantitative analyses of soil compaction energy with
relation to unit weight and moisture content are conducted. These analyses spot
the light on energy savings performed for soil compaction. The study shows that
as the compaction energy increases; the unit weight of the Jerash cohesive soil
increases and the optimum water content decreases. Generally, a soil with low
moisture content is less vulnerable to compaction than a soil with high
moisture content. But when the moisture content is too high, all the soil pores
are filled with water, so that the soil becomes less compressible where the
unit weight and strength characteristics decrease. The optimum energy value and
optimum water content are thus of great concern. The effect of energy on soil
unit weight is very large as the energy increases from 400 to 1400 KJ/m3 and after that level; the effect of energy on soil unit weight is very small.
Consequently, optimal compaction energy ranges from 1200 up to value 1400 KJ/m3,
where 50 to 60 blows can be applied and the optimal correlated water content is
between 14% - 15%.
