The laterite gravel found all over Kenya does not meet the engineering requirements to be used
as flexible paving materials in road construction due to its high plasticity and gradation as well
as other requirements like Los Angeles Abrasion (LAA), Soundness and ACV (Aggregate
Crushing Value).
As a result of this difficulty, high-quality aggregates with suitable engineering attributes must
be transported from their regions of origin to the building site. These vast amounts of material
must be transported can cause environment pollution and may raise project costs and durationsince the chosen resources must be produced and transported. In addition, using such high-
quality aggregate can cause a natural resource to run out.

Thus, in order to reduce or eliminate environmental risk, additional project costs, and the time
needed to transport the chosen materials, we must explore for acceptable and economical soil
stabilizing procedures for the existing material on site, due to the high expense of lime and
cement, which is used stabilize to laterite gravel, other materials must be utilized as a partial
replacement for both cement and lime. One such resource is a mixture of waste bagasse ash
and molasses.
