Abstract
This thesis deals with the study of the relative
effectiveness of common stabilizers i.e. cement and
lime and a by-product of our Steel Rolling Mills i.e.
billet-scales on a natural lateritic soil from the
site of Ahrradu Bello University Zaria still under
construction. It involves the determination of
liquid limit, plastic limit, grading analysis, maximum
dry density and CBR values. A tabular and graphical
representations were made. From the results of the
analysis some conclusions and recommendations were
made, which enhance the overall understanding of the
physical and engineering behaviour of the group of
soil as a highway materials.
It was found out that, with 2% of lime, 2% cement
and 2% billet-scales the A-2-4 subgroup of soil can be
upgraded to a fill material. Again with 4% lime,
2% cement and 6% billet-scales the lateritic soil
will meet the CBR requirement as a sub-base material.
But only 4% of cement is required to effectively
stabilize the A-2-4 sub-group of soil as a base
material. And that lime is not an effective means
of stabilizing silty-sand and billet-scales cannot
be commented as a base material with certainty until
higher percentages and/or compactive efforts are
tested.
