Abstract
Bituminous Stabilization of S1lty Sand is one method
of improving the engineering properties of the Soil so
that it can be used as fill. Sub-base and base
materials for construction. In order to improve these
properties, the following tests were carried out in the
laboratory, liquid limit, moisture content, specific
gravity, relationship between dry density and moisture
content, C.B.R, Triaxial, Absorption, Marshall Stability
flow and volume stability, using various percentages of
bitumen, lime and cement.
Different methods of obtaining bituminous
stabilization strength were used to compare with those
of other stabilization methods (Lime and Cement).
The results obtained show that under soaked
condition, 4% bitumen was economically suitable for fill
material, while 2% cement was good for fill, Sub-base
and base materials for light and medium traffic roads.
The lime stabilized Soil easily disintegrated into a
loose granular mass on touching. For the air cured
condition, 4% bitumen was adequate for use in fill, Subbase
and base material while 2% cement were equally
adequate.
The project will throw more light on the use of
bituminous stabilization for pavement construction.
